4 Commissioning

4.1 Mechanical mounting

The gateway provides a small housing for DIN rail mount. It can easily be opened using a screwdriver and

partially pulled out in order to set user ID (MAC ID), Baudrate and bus termination.

• Grid width 22,5 mm, height approx. 100 mm, depth approx. 110 mm

• For mounting onto 35 mm DIN rails

For mounting onto the DIN rail slide the gateway at its rear hinges onto the DIN rail and then press down to

lock.

4.2 Electrical connection

4.2.1 Electrical commissioning

• Do not carry out any electrical modifications at the gateway.

• Do not carry out any wiring work when the gateway is live.

• Make sure that the entire equipment is installed in line with EMC requirements. Ambient installation and

wiring affect the electromagnetic compatibility of the gateway. Install gateway and supply cables in

separate rooms or far away from cables with high interference emission (frequency converters, protections,

etc).

• Provide separate supply voltage for the gateway where working with consumers with high interference

emission.

• Connect the gateway to protective earth (PE) conductor using shielded cable. The braided shield must be

connected to cable gland or plug. Ideally, aim at a bilateral connection to protective earth (PE), i.e. housing

via mechanical assembly and cable shield via downstream devices. In case of earth loop problems, earth

on one side only as a minimum requirement.

Failure to observe these instructions may result in malfunctions, material damage or personal injury.

4.2.2 Supply voltage connection

Gateway and SPA are connected to power supply utilizing screw terminals 5 (GNDB) and 6 (UB) or 7

(GNDB) and 8 (UB). Terminals 5 and 7 as well as 6 and 8 are internally connected to each other for looping

the operating voltage further to other consumers (for example to the SPA).

4.2.3 Shield connection / functional earth

Connection of protective earth is at terminal 1 which at the same time serves for shield connection of the

RS485 bus. Pin 1 and the housing of the 9-pin D-Sub connector (DeviceNet) are connected to each other. PE

(protective earth) connection is additionally carried out by DIN rail mount. For this purpose the DIN rail must

be connected to functional earth utilizing low-impedance.

To prevent a bridge from the internal drain circuit to earth the DeviceNet Drain connection respectively the

DeviceNet cable shield must not be connected to the SUB-D connector housing.

4.3 Device settings

4.3.1 How to open the housing

Snap-lock

Setting the DeviceNet user ID (Mac ID) and Baudrate requires partial opening of the gateway housing.

Please use a small screw-driver, press-in the snap-locks provided on top and bottom behind the screw

terminals and pull out the housing halfway until stop so that the operating elements are accessible. The

housing is closed again by pulling it back to its original position until both locks snap in again.

4.3.2 Setting the DeviceNet user ID (Mac ID)

The DeviceNet user ID (Mac ID) is set decimally within the range from 00 to 63 using two BCD rotary

switches. (Any settings higher than 63 are automatically assigned 63)

Default: Mac ID 63

Example: 01

4.3.3 Setting the Baudrate

Binary setting of the Baudrate is by utilizing the 3-pole DIP switches 1 to 3.

Default : Baudrate 125kBit/s

5 DeviceNet interface description

5.1 Data exchange DeviceNet Master <-> Slave

DeviceNet was developed by Rockwell Automation and the ODVA (Open DeviceNet Vendor Association) as

an open fieldbus communication standard based on CAN protocol. DeviceNet is in line with European

Standard EN 50325 and specified and administered by ODVA. DeviceNet is an object-oriented bus system

operating according to the producer/consumer communication principle. DeviceNet appliances can be client

(Master) or server (Slave) or even both. Client and server may be either producer, consumer or both.

Layer 2 (Data Link Layer) is based on the Controller Area Network (CAN).

The DeviceNet network is a connecting structure for communication between maximum 64 bus users utilizing

Baudrates of 125, 250 or 500 kBaud. The DeviceNet topology provides besides the two signals CAN-L and

CAN-H for data transmission also two 24 VDC supply lines enabling the DeviceNet users to be directly

powered from the bus or from an external source (GK473 external supply only). The maximum length of the

DeviceNet depends on the selected cable size and Baudrate. Installation is according to bus topology –

trunkline/dropline- with bilateral terminating resistors. The terminating resistors provide 120 Ohm.

GK473 DeviceNet gateway operates as a Class 2 Slave in the DeviceNet bus network. The device supports

I/O Poll connections and Change-Of-State messages of the predefined Master Slave Connection Set. It does

not support "Explicit Unconnected Message Manager" (UCMM).

I/O Poll

While polling the DeviceNet-Master is transmitting a Poll Request to GK473 replied by the status information

stored in the GK473 on the connected RS485 sub bus and users .

The 48 Byte data packet comprises the following information:

The individual bits represent the respective status at the relating sub bus ID.

Byte 0..15 “SPA not in position”

Byte 16..31 “SPA in error state”

Byte 32..47 “SPA in time out state”

COS (Change of State)

The data content is according to I/O Poll.

GK473 will only produce and transfer data to the DeviceNet master upon any change of state at the RS485

sub bus. Utilizing the Change-of-State messages means a considerable reduction of data volume in the

DeviceNet bus.

After having implemented the COS connection user data amounting to 48 bytes will be transmitted once.

Second the message will only be transmitted (produced) if the previous state changes.

Advantage:

Normally all bytes are 0 -> all SPA’s are in position, no SPA error and no SPA time out.

Input data for the control will be only produced upon change of state.

This way the bus load is kept down to a minimum.

04.05.11 Villingen-Schwenningen, Germany

5.2 Data exchange DeviceNet <-> RS485 sub- bus

The Gateway is enabling communication between the SPA’s RS485 protocol and the DeviceNet fieldbus.

The PLC (DeviceNet Master) output data to the gateway comprise all commands relevant for the addressed

spindle position display. The command is completed by start and stop token as well as by CRC byte (cyclic

redundancy check) and forwarded by the gateway via RS485 interface.

In direction vice-versa, start and stop token as well as CRC byte (cyclic redundancy check) will be taken out

of the RS485 message, but latter is passed with unchanged content to the data block of a DeviceNet

message so that it is available at the PLC as consistent input data.

Furthermore, the gateway provides additional functions to relieve the master PLC and to simplify PLC

programming.

Autoscan SPA, Automated scan of the

BOOL 1

Default: 1= ON

During operation the gateway is performing automatic and cyclic scanning operations of all SPAs connected

to verify whether they are “in position”. Upon request this information is batched under a special command

for DeviceNet read-in. The AutoScan function relieves the CANopen master from proceeding cyclic SPA

scanning operations itself.

This operating mode is necessary to make the batched information objects (GK473 class Attribute 3..7)

provide valid data.

However, there might be situations where this is not desired

Several commands to the SPA are only valid for the time being until another command is received (for

example indicate SPA ID in the lower display line). The AutoScan attribute would make these commands

ineffective. Furthermore, the scanning procedure keeps the RS485 bus busy and consequently the

commands received from the DeviceNet master can be processed by the gateway faster with AutoScan off.

Transparent transfer of SPA command

ARRAY[16]

of USINT

This object is for transparent transfer of all commands to the spindle position displays (SPA) utilizing the

vendor specific service Code 0x32.

Basically there is a transparent transfer of all commands under codes „A“...“z“ from DeviceNet Master to SPA

and vice-versa what enables addressing the SPAs individually or collectively by broadcast command. The

gateway does not verify whether a registered SPA is connected or not, neither the command code is verified.

The gateway replies to every command received by the DeviceNet-Master (PLC).

Response is by

• transparent transfer of the SPA reply, if an individual SPA was addressed and duly replied

• an abort message if the addressed SPA did not reply within the timeout window (approx. 100 ms)

Any timeout administered by the DeviceNet Master for monitoring of gateway reply should not be less than

400 ms.

The DeviceNet Master transmits to GK473 the transmission data within the limits SOH and EOT out of the

complete command to the addressed spindle position display (SPA). Length is always 16 bytes since digits

not utilized are filled up with 0.

Example: Programming the target (profile no = 17; target = -12,50; SPA identifier 0)

SOH Adr Cmd Profile no. = 17 Target = -12,50 EOT CRC

Transmission

01h 20h 53h 31h 37h 2Dh 30h 31h 32h 35h 30h 04h FBh

In the other direction (responding SPA) start and stop token as well as CRC byte are taken out of the RS485

message which in its remaining content is transferred unchanged into the data block of a DeviceNet message

so that it will be available at the PLC as consistent input data.

Example: Programming the target (profile no = 17; target = -12,50; SPA identifier 0)

SOH Adr Cmd Profile no. = 17 Target = -12,50 EOT CRC

Response

01h 20h 53h 31h 37h 2Dh 30h 31h 32h 35h 30h 04h FBh

Example for transparent transfer of a SPA command

SPA identifier 0 (0x20) command: read current value „R“ (0x52)

Excerpt of operating manual SPA N140 :

This command is for reading the 6-digit current value (bottom line of the display). Data volume is always 6

Byte. A negative value comes with “-“ sign (2Dh) followed by 5 data Bytes. Positive values are returned as 6

data Bytes less sign. Values of less than 6 (5) digits come with preceding zeroes.

Example: Current value = -32,50

Batched information : GK473 class Instance Attribute 3..7

These objects are for convenient monitoring of the RS485 sub bus state and consequently the status of all

spindle position displays.

Prior condition of updated data is active Auto Scan SPA what means cyclic scanning of the RS485 sub bus.

Any change of state is saved in the GK473 memory for optional read-in into the PLC by Explicit Message, I/O

Poll or Change of State (COS).
