S7-1200 Transparent CAN and SAE J1939 ECU

Ixxat Support CAN/CANOpen PLC Extensions
#1

Hello,

I’m trying to read CAN frames that are sent at regular time intervals from an engine ECU, but it seems that all frames have 29bit identifiers (SAE J1939 compliant).

The CM CANopen module is therefore needed for “listening” only, since I need the precise value of RPMs and other values for maintenance purposes (i.e. temperatures)

Is there any way to acquire the CAN 2.0A frames and process them in TiA Portal/manually? Or other ways to circumvent the 11-bit ID limitations?

Thanks in advance

Contacted support, the device is NOT Compatible with any extended 29-bit messages (CAN 2.0B / SAE J1939 etc…)

Thank you for your time
