Control of CAN modules
The CAN modules are configured via the ETH or USB interface of the module. In addition to the module address and baud rate, an automatic send and receive mode can also be configured using the ICT-Tool included in the scope of delivery.
TX mode
In TX mode, the modules are able to automatically send CAN packets at a freely definable time interval (milliseconds to seconds). The adjacent figure shows the configuration of a TX packet, which is sent to CAN address 200 every 1000ms and contains the logical status of the first 64 optocoupler inputs.
RX mode
In RX mode, CAN packets can be received automatically and output to the digital or analog outputs of the module. Up to 4 CAN addresses can be configured individually. The adjacent figure shows the configuration of an RX packet, among other things. The logical data received at CAN address 0x10 is transmitted to relay outputs 1-64.
DELIB command mode
In DELIB command mode, the module's registers are specifically accessed via a CAN protocol developed by DEDITEC. The module expects the CAN messages on a CAN address defined in command mode. Read and write accesses with different data lengths (BYTE, WORD, LONG) are possible. Details on the protocol structure and register assignment can be found in the "Protocols & Register Assignment" manual in the download area.
