4.2 Transparent mode
In Transparent mode the data will be accessed by different function blocks. The module needs to
be configured appropriately. This may be done by using Wago-IO-Check.
If the configuration should be done by the CoDeSys application the function blocks
CAN_FullConfig and CAN_Communication have to be used.
If the module size and acyclic channel size is configured correct, both channels will show
MBX_OK.
The function block CAN_FullConfig allows configuring the module.
An additional function block CAN_FullConfigCheck allows to check module settings by compar-
ing the module internal CRC against the calculated CRC from variable tConfigData. A configura-
tion download may be performed depending on the result of the CRC check.
Different function blocks are provided by the WagoLib_CAN_Gateway_02.lib library. They are
mostly organized in the folders CAN_Layer2 and CAN_CIA405 to program the data exchange
either with CAN or even CANopen devices.
