PN/CAN Gateway, PROFINET/CANopen Slave | Version 2 | 1/26/2021
25
Only those SDOs that are relevant for the PLC application must be specified in the configuration. SDOs,
which are available in the EDS-/DCF file but not configured in the PLC, still exist in PN/CAN-Gateway and
can be accessed via CANopen.
For modules which read or write SDOs with 2 or 4 bytes, you can additionally set whether the value
from or to the CAN bus stays in its byte order or should be rotated.
6.2.4
Maximum extension of a PN/CAN Gateway configuration
The maximum extension of a project configuration is limited by the following parameters:
•
The CANopen Device can manage up to 16 RPDOs and 16 TPDOs
•
There are 470 slots for inserting modules (SDOs modules with 1, 2, 4 bytes)
•
The PROFINET input data can be up to 1440 bytes long
•
The PROFINET output data can be up to 1440 bytes long
Exceeding the limits is reported either by the hardware configurator or by an error code at the device
status of the PN/CAN Gateway.
