ETHERNETARCNET Routing

Note

Routing is available as of PLC firmware version V1.3.

For controllers with ETHERNET and ARCNET Communication Module, the PLCs connected via ARCNET can be programmed using the PLC ETHERNET interface.

For each PLC connected via ARCNET, one gateway channel has to be defined. To do this, select “Online/Communication Parameters” and press the button “New” in the “Communication Parameters” window. In the appearing window, enter a name for the channel (for example TcpIp: PLC1:169.29.44.48 -> ARC_2) and select the driver “ABB Tcp/Ip Level 2 AC” from the device list.

For example, set the communication parameters as follows for the configuration shown above:

Parameter Possible values Meaning
Address 10.49.88.205 IP address of PLC 1
Port 1200 Port 1200
Timeout (ms) 2000 Timeout [ms] for response
Routing levels 1 Single-level routing
Communication Module (Level 1) Line 0 Communication Module for level 1 (internal: ARCNET)
Channel (Level 1) 0 Channel on Communication Module level 1
Address (Level 1) 2, 0, 0, 0, 0 ARCNET node of the target PLC (Node 2)
Communication Module (Level 2) 0 No level 2
Channel (Level 2) 0  
Address (Level 2) 0, 0, 0, 0, 0  
Block size 480 Bytes per block: 128…1430
Motorola byteorder Yes  

For the parameter “Communication Module (Level 1)”, enter the slot where the ARCNET Communication Module “Line 0” is inserted (the ARCNET Communication Module is always the internal Communication Module).

The ARCNET Communication Module has only one communication channel. Thus, the “Channel” value must always be 0.

For the ARCNET Communication Module, 1 byte is required for the subscriber address (node). The address (Node=2) of the target PLC is entered to the first byte of the address byte.

The default value for the block size is 1430. If routing on ARCNET is required (and “large ARCNET packages” are enabled for the target PLC), the block size can be increased to 480 bytes. Values in the range of 227 .. 245 are not allowed.
