2. Introducon

When starng an implementaon of the Anybus CompactCom 30 or the Anybus CompactCom 40, host

applicaon example code is available to speed up the development process. The host applicaon example

code includes a driver, which acts as glue between the Anybus CompactCom module and the host applicaon.

The driver has an API (Applicaon Programming Interface), which denes a common interface to the driver. Also

included in the example code is an example applicaon which makes use of the API to form an applicaon that

can be used as a base for the nal product.

NOTE

This guide is developed to describe a step-by-step implementaon of the Anybus CompactCom

driver and example applicaon. The programmer is requested to have basic knowledge in

the Anybus CompactCom object model and the communicaon protocol before starng the

implementaon.

This document is based on the contents of version 3.08 of the host applicaon example code.

The guide is divided into two steps:

1. The adaptaons needed for the target hardware are done here and a simple applicaon is

developed. The goal with this step is to make sure that the hardware specic code is working

and that it is possible to connect to the network and exchange a limited amount of data.

2. The code is adapted to the target product. The goal with this step is to customize the code and

add to it, to congure the data that will be sent on the network. Aer this, the applicaon can

be further extended and improved.

The driver is fully OS independent and it can even be used without an operang system, if required.

Furthermore, it can be used for Anybus CompactCom 30 modules as well as Anybus CompactCom 40 modules.

The driver supports mulple operang modes, where selecon of one of the implemented modes can be made

at runme.

It is possible to use modules from the 30- and the 40-series in the same applicaon, see

30- and 40-series Modules in the Same Applicaon, p. 51 (page 51).

The host applicaon example code is available in dierent versions for dierent plaorms. At this me, the

plaorms depicted below are available.

Each folder contains all les for a specic plaorm/development environment.

2.1. Overview

Parts of the driver code need to be adapted to the host applicaon plaorm. This generally includes funcons

which access the Anybus host interface, or funcons which need to be adapted to integrate the driver into the

host system. The gure below shows the dierent parts of the host applicaon example code.

Figure 1. Soware Overview

The host applicaon example code is divided into ve dierent folders depending on the funconality and

whether or not the les need to be adapted by the user.

Table 1. Folder Structure

/abcc_abp (part of the driver - read only) Contains all Anybus object and communicaon protocol denions.

Files may be updated when new Anybus CompactCom releases are

available.

These les are read only and must not be changed in any way by the

user.

/abcc_drv (part of the driver - read only) Contains source and header les for the driver. Files may be updated

when new Anybus CompactCom releases are available.

These les are read only and must not be changed in any way by the

user.

/abcc_adapt Contains conguraon les. These les must be modied by the user to

adapt the driver and the example code to the system environment.

NOTE

If using example code adjusted to a specic plaorm,

most of the adaptaons needed in this folder are

already completed.

/abcc_obj Includes all Anybus host applicaon object implementaons. These les

can be modied if needed, for opmizaon and/or addional features.

/example_app Example applicaon including:

• Main state machine to handle inializaon, restart, normal and error

states.

• State machine paerns to show how to send Anybus CompactCom

messages.

•Implementaon of callbacks required by the driver.

•Denion of ADIs, Applicaon Data Instances, and default process

data mapping setup.

These les have to be adapted to the applicaon by the programmer.

Addionally they may be modied for opmizaon and/or addional

features.

Overview Anybus® CompactCom™ 40

2.2. Preparaons

Before connuing, try to answer as many of the quesons below as possible. This will make decisions during

implementaon easier. It is also good to have access to the hardware schemacs of the target hardware during

the implementaon.

Step One

Consider the following quesons:

• What operang mode, or modes, shall be used in the design?

• What communicaon interfaces shall be used to communicate with the CompactCom in the design?

• Which networks shall be used in the design?

• Are the networks available in the CompactCom 40 series or is there also a need to use CompactCom 30 series

modules?

• Are the Module Idencaon pins connected to the host processor?

• Are the Module Detecon pins connected to the host processor?

Step Two

Consider the following quesons:

• Is the interrupt signal implemented in the hardware?

• Which parameters/data shall be communicated on the network in the nal product?

– Name

– Data type

– Number of elements

– Read/Write access

– Acyclic access, Cyclic access

– Max/Min/Default values

• Which events (diagnoscs) shall be reported on the network?

• What network idencaon parameters are available? E.g. Vendor ID, Product Code, ID number etc.

Anybus® CompactCom™ 40 Preparaons

Page 6 of 54 HMSI-27-334 Version 1.8

3. Step One

3.1. System Adaptaon and Applicaon Development

When this step is completed you will have...

• ...implemented the system specic funcons needed to communicate with the Anybus CompactCom.

• ...compiled the host applicaon example code with default sengs.

• ...exchanged data between the host applicaon and the network master/scanner.

3.2. System Set-up

These denes can be found in abcc_adapt/abcc_td.h.

General sengs for the system environment, to be used in the driver, are congured here.

3.2.1. Big- or Lile Endian

Congure if the host applicaon is a big endian system or a lile endian system. Dene

ABCC_SYS_BIG_ENDIAN if it is a big endian system. Do not dene (leave as default) if the host applicaon is a

lile endian system.

#define ABCC_SYS_BIG_ENDIAN /* Big endian host application */

/* #define ABCC_SYS_BIG_ENDIAN */ /* Little endian host application */

3.2.2. 16-bit Char System

Congure if the host applicaon is a 16-bit char system or an 8-bit char system (i.e. if the smallest addressable

type is 8-bit or 16-bit). Dene ABCC_SYS_16BIT_CHAR if it is a 16-bit char system. Do not dene (leave as

default) if it is an 8-bit char system. Conguring 16-bit char on an 8-bit char system is not recommended.

#define ABCC_SYS_16_BIT_CHAR /* 16 bit char system */

/* #define ABCC_SYS_16_BIT_CHAR */ /* 8 bit char system */

3.2.3. Extended Bus Endian Dierence

If the endianness for the external parallel data bus diers from the internal data bus endianness, enable this

dene. If parallel 16-bit operang mode is not used, this dene is ignored.

#define ABCC_CFG_PAR_EXT_BUS_ENDIAN_DIFF (FALSE)

Step One Anybus® CompactCom™ 40

HMSI-27-334 Version 1.8 Page 7 of 54

3.2.4. Data Types

Dene the Data Types for the current system. For 16-bit char systems, all 8-bit types shall be typed to 16-bit

types. The following data types must be dened:

BOOL Standard boolean data type.

BOOL8 Standard boolean data type, 8-bit.

INT8 Standard signed 8-bit data type.

INT16 Standard singed 16-bit data type.

INT32 Standard signed 32-bit data type.

UINT8 Standard unsigned 8-bit data type.

UINT16 Standard unsigned 16-bit data type.

UINT32 Standard unsigned 32-bit data type.

FLOAT32 Float (according to IEC 60559).

3.3. Anybus CompactCom Set-up

These denes and funcons are found in abcc_adapt/abcc_drv_cfg.h. Detailed descripons are

available in abcc_drv/inc/abcc_cfg.h.

Sengs for how to use and communicate with the Anybus CompactCom. For example, Operang mode,

interrupt handling, and memory handling, are congured here.

3.3.1. Communicaon Interfaces and Operang Modes

Dene the communicaon interfaces and the operang mode between the host applicaon and the

CompactCom (Parallel, SPI, Serial), that will be used in the implementaon. There are several possibilies to

set the operang mode depending on how the host applicaon is intended to communicate with the Anybus and

also depending on how the operang mode is selected by the user.

• First, dene all communicaon interfaces that will be supported by the implementaon. All interfaces that will

be used must be dened here, otherwise an error will be reported later on. Only dene the interfaces that will

really be used, since every enabled interface will increase the compiled code size.

Only for 40-series.

#define ABCC_CFG_DRV_PARALLEL ( TRUE ) /* Parallel, 8/16-bit, event

mode */

#define ABCC_CFG_DRV_SPI ( FALSE ) /* SPI */

For both 30-series and 40-series.

#define ABCC_CFG_DRV_SERIAL ( FALSE ) /* Serial */

#define ABCC_CFG_DRV_PARALLEL_30 ( TRUE ) /* Parallel, 8-bit, half

duplex */

NOTE

ABCC_CFG_DRV_SERIAL and ABCC_CFG_DRV_PARALLEL_30 use the CompactCom half

duplex communicaon protocol, with limited data sizes for process data and message data.

Anybus® CompactCom™ 40 Anybus CompactCom Set-up

Page 8 of 54 HMSI-27-334 Version 1.8

• Get the operang mode from external hardware - If the operang mode is set e.g. via a dipswitch connected

to the host applicaon processor or via an HMI controller, dene the ABCC_CFG_OP_MODE_GETTABLE and

implement the funcon ABCC_SYS_GetOpmode() in abcc_adapt/abcc_sys_adapt.c.

#define ABCC_CFG_OP_MODE_GETTABLE ( TRUE )

If not dened, the operang mode denes must be explicitly dened for the specic module type. (See

ABCC_CFG_ABCC_OP_MODE_30 and ABCC_CFG_ABCC_OP_MODE_40 below (page 9)).

• If the operang mode pins on the CompactCom host connector can be controlled by the host processor,

dene ABCC_CFG_OP_MODE_SETTABLE and implement the funcon ABCC_SYS_SetOpmode() in

abcc_adapt/abcc_sys_adapt.c.

#define ABCC_CFG_OP_MODE_SETTABLE ( TRUE )

If not dened, it is assumed that the operang mode signals of the CompactCom host connector are xed or

controlled by external hardware, e.g. a dip-switch.

• If only one operang mode per module type (CompactCom 30 and CompactCom 40) is used, dene

the operang mode with ABCC_CFG_ABCC_OP_MODE_30 and ABCC_CFG_ABCC_OP_MODE_40. The

available operang modes (ABP_OP_MODE_X) can be found in abcc_abp/abp.h.

#define ABCC_CFG_ABCC_OP_MODE_30 ABP_OP_MODE_8_BIT_PARALLEL

#define ABCC_CFG_ABCC_OP_MODE_40 ABP_OP_MODE_16_BIT_PARALLEL

If none of these denes are set, ABCC_SYS_GetOpmode() must be implemented to retrieve the operang

mode from external hardware. See ABCC_CFG_OP_MODE_GETTABLE (page 9) above.

3.3.2. Parallel Operang Mode Specics

NOTE

If parallel operang mode (8-bit or 16-bit) is not used, this secon can be ignored.

If direct access to the CompactCom memory is available (the host controller provides dedicated signals to access

external SRAM), dene ABCC_CFG_MEMORY_MAPPED_ACCESS to TRUE and dene the base address with

ABCC_CFG_PARALLEL_BASE_ADR (this address must be dened to suit the host plaorm).

#define ABCC_CFG_MEMORY_MAPPED_ACCESS ( TRUE )

#define ABCC_CFG_PARALLEL_BASE_ADR ( 0x00000000 )

If direct access to the CompactCom memory is not available, several funcons to read and write

data must be implemented in abcc_adapt/abcc_sys_adapt.c (described in abcc_drv/inc/

abcc_sys_adapt_par.h).

NOTE

The recommendaon is to have direct access to the CompactCom memory if possible for a simpler

and most oen faster implementaon.

Anybus CompactCom Set-up Anybus® CompactCom™ 40

HMSI-27-334 Version 1.8 Page 9 of 54

3.3.3. SPI Operang Mode Specics

NOTE

Only for 40-series. If SPI operang mode is not used, this secon can be ignored.

The length of an SPI message fragment in bytes per SPI transacon is dened with

ABCC_CFG_SPI_MSG_FRAG_LEN.

If the ABCC_CFG_SPI_MSG_FRAG_LEN value is less than the largest message to be transmied, the sending

or receiving of a message may be fragmented and take several SPI transacons to be completed. Each SPI

transacon will have a message eld of this length regardless if a message is present or not. If messages are

important the fragment length should be set to the largest message to avoid fragmentaon. If IO data are

important the message fragment length should be set to a smaller value to speed up the SPI transacon.

For high message performance a fragment length up to 1524 octets is supported. The message header is 12

octets, so 16 or 32 octets will be enough to support small messages without fragmentaon.

#define ABCC_CFG_SPI_MSG_FRAG_LEN ( 16 )

3.3.4. Module ID and Module Detect Sengs

• If the Module Idencaon pins (MI) on the CompactCom host connector are not connected

to the host processor, ABCC_CFG_MODULE_ID_PINS_CONN must be dened as FALSE, and

ABCC_CFG_ABCC_MODULE_ID must be dened to the correct CompactCom module ID that corresponds to

the module ID of the used device. If dened, it shall be set to the correct ABP_MODULE_ID_X denion from

abcc_abp/abp.h.

If ABCC_CFG_MODULE_ID_PINS_CONN is dened as TRUE, the funcon

ABCC_SYS_ReadModuleId() in abcc_adapt/abcc_sys_adapt.c must be implemented.

NOTE

The recommendaon is to connect the Module ID pins on the applicaon connector directly to

GPIO-pins on the host processor and implement the ABCC_SYS_ReadModuleId() funcon.

#define ABCC_CFG_ABCC_MODULE_ID ABP_MODULE_ID_ACTIVE_ABCC40

#define ABCC_CFG_MODULE_ID_PINS_CONN ( TRUE )

• If the Module Detect pins (MD) in the host applicaon connector are connected to the host processor, the

ABCC_CFG_MOD_DETECT_PINS_CONN shall be set to TRUE and the ABCC_SYS_ModuleDetect()

funcon in abcc_adapt/abcc_sys_adapt.c must be implemented.

#define ABCC_CFG_MOD_DETECT_PINS_CONN ( TRUE )

3.3.5. Message and Process Data Sengs

Leave the following denes with the default values for now.

#define ABCC_CFG_MAX_NUM_APPL_CMDS ( 2 )

#define ABCC_CFG_MAX_NUM_ABCC_CMDS ( 2 )

#define ABCC_CFG_MAX_MSG_SIZE ( 255 )

#define ABCC_CFG_MAX_PROCESS_DATA_SIZE ( 512 )

#define ABCC_CFG_REMAP_SUPPORT_ENABLED ( FALSE )

#define ABCC_CFG_CMD_SEQ_MAX_NUM_RETRIES ( 0 )

#define ABCC_CFG_MAX_NUM_CMD_SEQ ( 2 )

NOTE

The dierent plaorms can have dierent default values depending on the available resources.

3.3.6. Interrupt Handling

If the IRQ pin is connected the driver can be congured to check if an event has occurred

even if the interrupt is disabled. It can be used e.g. to detect the CompactCom power up event.

Dene ABCC_CFG_POLL_ABCC_IRQ_PIN to enable this funconality, and implement the funcon

ABCC_SYS_IsAbccInterruptActive() in abcc_adapt/abcc_sys_adapt.c.

#define ABCC_CFG_POLL_ABCC_IRQ_PIN ( TRUE )

In this step, we will not use the interrupt funconality, which means that we will dene

ABCC_CFG_INT_ENABLED as FALSE.

If the IRQ pin is not connected, this dene must be set to false.

#define ABCC_CFG_INT_ENABLED ( FALSE )

3.3.7. Communicaon Watchdog Sengs

The meout for the CompactCom communicaon watchdog is congured with ABCC_CFG_WD_TIMEOUT_MS.

If a meout occurs, the callback funcon ABCC_CbfWdTimeout() is called.

NOTE

The watchdog funconality is only supported by the SPI-, serial- and parallel30 (half duplex)

operang modes.

#define ABCC_CFG_WD_TIMEOUT_MS ( 1000 )

3.3.8. ADI Sengs

Leave the following denes with the default values for now.

#define ABCC_CFG_STRUCT_DATA_TYPE ( FALSE )

#define ABCC_CFG_ADI_GET_SET_CALLBACK ( FALSE )

#define ABCC_CFG_64BIT_ADI_SUPPORT ( FALSE )

3.3.9. Debug Event Print Sengs

For development purposes, a number of debug funcons are available for the developer. The following denes

aects debug printouts from the driver. If addional printouts are needed from the applicaon code, use the

ported funcon ABCC_PORT_DebugPrint() in abcc_adapt/abcc_sw_port.h.

• Enable or disable the error reporng callback funcon ABCC_CbfDriverError() with

ABCC_CFG_ERR_REPORTING_ENABLED. The funcon is described in abcc_drv/inc/abcc.h.

#define ABCC_CFG_ERR_REPORTING_ENABLED ( TRUE )

• Enable or disable driver support for print out of debug events within the driver

with ABCC_CFG_DEBUG_EVENT_ENABLED. ABCC_PORT_DebugPrint() in abcc_adapt/

abcc_sw_port.h will be used to print debug informaon.

#define ABCC_CFG_DEBUG_EVENT_ENABLED ( TRUE )

• Enable or disable printout of debug informaon, such as le name and line number, when

ABCC_CbfDriverError() is called with ABCC_CFG_DEBUG_ERR_ENABLED.

#define ABCC_CFG_DEBUG_ERR_ENABLED ( FALSE )

• Enable or disable printout of received and sent messages with ABCC_CFG_DEBUG_MESSAGING. Related

events such as buer allocaon and queuing informaon is also printed.

#define ABCC_CFG_DEBUG_MESSAGING ( FALSE )

• Enable or disable printout of command sequencer acons with ABCC_CFG_DEBUG_CMD_SEQ_ENABLED.

#define ABCC_CFG_DEBUG_CMD_SEQ_ENABLED ( FALSE )

3.3.10. Startup Time

If the CompactCom IRQ pin is connected, ABCC_CFG_STARTUP_TIME_MS will be used as

a meout while waing for the CompactCom to become ready for communicaon. An error

(APPL_MODULE_NOT_ANSWERING) will be reported if the start-up interrupt is not received within this me. If

the interrupt pin is not available ABCC_CFG_STARTUP_TIME_MS will serve as me to wait before starng to

communicate with the CompactCom. If not dened, the default value is 1500 ms.

#define ABCC_CFG_STARTUP_TIME_MS ( 1500 )

NOTE

If possible, the recommendaon is to use the startup interrupt (opon available for the SPI and

parallel communicaon interfaces).

3.4. System Adaptaon Funcons

A number of funcons must be implemented for the driver to be able to access the Anybus CompactCom.

The funcons shall be implemented in abcc_adapt/abcc_sys_adapt.c. The funcons are described per

operang mode in the les specied below.

• General funcons: abcc_drv/inc/abcc_sys_adapt.h

• SPI operang mode: abcc_drv/inc/abcc_sys_adapt_spi.h

• Parallel operang mode: abcc_drv/inc/abcc_sys_adapt_par.h

• Serial operang mode: abcc_drv/inc/abcc_sys_adapt_ser.h

3.4.1. General Funcons

These funcons can be found in abcc_drv/inc/abcc_sys_adapt.h.

ABCC_SYS_HwInit()

This funcon can be used to iniate the hardware required to communicate with the CompactCom device (e.g.

conguring the direcon and inial values of used host processor port pins). This funcon shall be called once

during the power up inializaon.

NOTE

Make sure that the CompactCom is kept in reset state when returning from this funcon.

ABCC_SYS_Init()

This funcon is called by the driver at start-up and restart of the driver. If needed, any hardware or system

dependent inializaon shall be done here. If not used, leave the funcon empty.

ABCC_SYS_Close()

Called from the driver if the driver is terminated. If resources were allocated in ABCC_SYS_Init() it is

recommended to close or free them in this funcon. If not used, leave the funcon empty.

ABCC_SYS_HWReset()

This funcon must be implemented to pull the reset pin on the Anybus CompactCom interface to low.

ABCC_SYS_HWReleaseReset()

This funcon must be implemented to set the reset pin on the Anybus CompactCom interface to high.

ABCC_SYS_AbccInterruptEnable()

For now, interrupt will be disabled. Leave this funcon empty.

ABCC_SYS_AbccInterruptDisable()

For now, interrupt will be disabled. Leave this funcon empty.

ABCC_SYS_IsAbccInterruptActive()

If the interrupt pin (IRQ) is connected to the host processor, this funcon shall read the interrupt signal from

the CompactCom and return TRUE if the interrupt pin is low (i.e. interrupt is acve) and return FALSE if

the interrupt pin is high (i.e. the interrupt is inacve). It is used to enable polling of the interrupt pin of the

CompactCom interface if interrupts are not enabled.

ABCC_SYS_SyncInterruptEnable()

For now, synchronizaon will be disabled. Leave this funcon empty.

ABCC_SYS_SyncInterruptDisable()

For now, synchronizaon will be disabled. Leave this funcon empty.

3.4.2. SPI Operang Mode

NOTE

Only for 40-series. If SPI operang mode is not used, the funcons below are never called, and this

secon can be ignored.

These funcons can be found in abcc_drv/inc/abcc_sys_adapt_spi.h.

ABCC_SYS_SpiRegDataReceived(ABCC_SYS_SpiDataReceivedCbfType pnDataReceived)

Registers the callback funcon that shall be called when new data is received (MISO frame received).

Example 1.

static ABCC_SYS_SpiDataReceivedCbfType pnDataReadyCbf;

void ABCC_SYS_SpiRegDataReceived(

ABCC_SYS_SpiDataReceivedCbfType pnDataReceived

)

{

pnDataReadyCbf = pnDataReceived;

}

ABCC_SYS_SpiSendReceive(void* pxSendDataBuffer, void* pxReceiveDataBuffer,

UINT16 iLength)

Handles sending and receiving of data in SPI mode.

Two buers are provided, one with a MOSI data frame to be sent and one buer to store the received MISO

frame.
