The IO_Module function block enables communication with the OX012-x10 expansion module so that

additional outputs can be used.

Configure CAN

Set up CAN so that CAN messages can be transmitted to and from the I/O module.

Input Type Range Description

CAN Bus —— In the GUIDE template, identify the CAN bus that contains CAN messages to and from the I/O

module. Route this bus to the CAN input on this function block.

CAN messages sent from the I/O module to the function block contain information about the

I/O modules’ inputs, outputs and configuration. CAN messages sent to the I/O module from the

function block set outputs and configurations.

Baudrate U32 50000–1000000 The Baudrate is the speed of the CAN Port.

Port Port —— Assigns the hardware CAN port that transmits the data.

AddrMode U8 0–2 I/O module addressing mode.

0: Variable ID addressing mode. The I/O module Tx and Rx message identifiers are determined

by the I/O module measuring the voltage on its CAN shield input and matching that value with a

predefined range and matching identifiers in the I/O Module CAN Message Identifiers table. The

CAN messages use 11 bit identifiers in this mode.

1: Predefined ID addressing mode. The I/O module Tx and Rx message identifiers are

determined by Node/N1. These identifiers are selected by matching to the N1 value in the I/O

Module CAN Message Identifiers table. The CAN messages use 11 bit identifiers in this mode.

2: Fixed ID addressing mode. The I/O module Tx and Rx message identifiers are determined

directly by setting Tx ID and Rx ID. The CAN messages use either 11 bit or 29 bit identifiers in

this mode, as determined by Frame.

Tx ID U32 0x00–0x1FFFFFFF Tx ID is the CAN message identifier used by the function block for sending messages to the I/O

module when using the Fixed ID addressing mode.

When using the service tool to configure the I/O module, this value corresponds to the Rx

parameter saved on the I/O module.

Rx ID U32 0x00–0x1FFFFFFF Rx ID is the CAN message identifier used by the function block for receiving messages from the

I/O module when using the Fixed ID addressing mode.

When using the service tool to configure the I/O module, this value corresponds to the Tx

parameter saved on the I/O module.

Frame U8 0–1 Sets CAN message identifier length when using the Fixed ID addressing mode.

0: 11 bit ID

1: 29 bit ID

Node/N1 U8 0–15 The KWP2000 node address used for communications between the I/O module and the PLUS+1

Service Tool is Node/N1 x 8. For Variable ID addressing mode and Predefined addressing mode

this value also determines the CAN.

Net U8 0–255 KWP2000 network used for communications between the I/O module and the PLUS+1

Service

Tool.

Enable BOOL —— Enables the function block to send CAN messages to the I/O module. An F/T transition or T at

power up starts initialization.

Enbl_RecheckCRC BOOL —— Determines if the I/O module CRC is periodically checked to ensure the device’s configuration

matches the function block’s configuration.

T: The CRC is requested from the I/O module and compared every 5 seconds.

F: The CRC is only requested from the I/O module during initialization.

Configuring Communications

The parameters that control the communication between a controller and an I/O module are described.

Variable Addressing Mode

Variable addressing mode is the default addressing mode of the I/O module, but it is not the default

mode for the function block.

When the device is powered, the CAN shield input voltage is measured. Communication parameters are

determined from the I/O Module CAN Message Identifiers table. For proper communication between the

function block and the I/O module, the corresponding N1 value from the table must be entered in the

function block and AddrMode must be set to 0.

Every time the device is powered, the CAN shield input voltage must be within the same N1 range for the

function block and device to reach the Configured status. After the device is powered, the CAN shield

input voltage has no effect on communication.

Predefined Addressing Mode

Predefined addressing mode is the default addressing mode for the function block, but it is not the

default mode for the I/O module.

In this mode, the I/O module reads the N1 value stored in non-volatile memory (EEPROM).

Because the function block and the I/O module use different default addressing modes, as long as the N1

value determined in the I/O module matches the N1 value set in the function block, the device is

configured using predefined addressing mode during all subsequent power cycles. As such, the proper

CAN shield voltage is only required during the first device initialization.

If setting the CAN shield voltage is not practical, use the PLUS+1

Service Tool to set the AddrMode to 1

and to set the required N1 value.

Fixed Addressing Mode

Fixed addressing mode allows for any pair of CAN message identifiers to be used for I/O module

communication.

In this mode, the I/O module relies on the RX_ID, TX_ID, and Frame parameters for communication with

the function block. Use the PLUS+1

Service Tool to set the proper values to match the function block and

to set the AddrMode.

Volatile Parameters

Once initial communication is established, all volatile parameter configuration messages are sent to the

I/O module.

Non-Volatile Parameters

After volatile parameters are configured, the function block sends a request for the configuration CRC to

the I/O module.

If this number matches the locally calculated value, then the configurations stored on the I/O module

match those set in the function block. If the numbers do not match, then all configuration commands are

sent and the CRC is requested again.

You can use the PLUS+1

Service Tool to access all non-volatile parameters on the I/O module.

Timing Configurations

Timing for messages to and from the I/O module is established after all other configurations are sent.

CAN Bus Load

Adjust the average amount of message transmissions on the CAN bus to allow for bursts and other

increased message transmission situations.

Any CAN bus has a maximum message transmission capacity. So, to allow for situations that can cause

increases in messages, minimize the CAN bus load.

The CAN bus load is the average amount of message transmission on a CAN bus. Use the PLUS+1

CG150

USB/CAN gateway and CANKing software to view CAN bus loads.

PLUS+1

I/O modules communicate with their associated controllers over a CAN bus. System developers

can adjust I/O module RepTime and TimeOut parameters to manage CAN bus loading. Increasing these

times reduces the CAN bus load. Decreasing these times increases CAN bus load.

CAN Message Identifiers

The function block uses the following message identifiers to enable communication between the

controller and the I/O module.

I/O Module CAN Message Identifiers

CAN Shield Voltage [mV] N1 KWP2000 Node Tx ID Rx ID

0 – 299 0 0 0x180 0x300

Troubleshooting

Find out how to ensure the outputs of the I/O module function properly, and make sure your changes to

parameters are saved.

Problem Cause Solution

Outputs of I/O module do not

function as expected. Configured is

always false.

The I/O module is using variable address mode

and the CAN shield voltage does not fall within

the range matching the function block’s N1

value.

Use the I/O Module CAN Message Identifiers table to find the

correct voltage and ensure it is applied to the CAN shield

during power up.

Change the N1 value in the function block to match the

voltage applied to the CAN shield.

Danfoss | July 2018 11063396 | AQ00000105en-US0101

Problem Cause Solution

Incompat_HW is true. The function block is

communicating with a device other than the I/O

module.

Ensure the proper addressing mode and corresponding

communication parameters are set on both the I/O module

and the function block.

It is possible the I/O module is correctly configured, but a

second I/O module has a similar configuration. Review

configuration and make changes to the other I/O modules.

Incompat_Protocl is true. The firmware on the

I/O module uses a version of the I/O Protocol less

than 2.00.

Update the I/O module with the latest firmware.

Incompat_Protocl is true. The firmware on the

I/O module uses a version of the I/O Protocol

later than version 2.99.

Replace the function block by using the latest available

HWD file.

When changing the I/O module ’s

parameters with the PLUS+1

Service

Tool, those changes are not properly

saved.

A function block detects the changes and resets

the parameters to the values specified in the

function block.

Disconnect the function block’s controller before making

parameter changes. If the changes do not result in different

CAN message identifiers for the I/O module, then

reconnecting the controller results in the parameters

reverting back to the values set in the function block.
