Hello everyone, I have encountered a problem.When using CANOPEN communication, there are specific messages that cannot be received, most of them can be received normally, and the ones that cannot be received normally are 16#391, 16#083, 085, 087, 089, 08B, 08D, and 08F, and the ones that cannot be received in a separate test can’t be received either, and the Can messages can be seen by using the canmoon tool, There are also errors 66 and 67 in the CANopenRegisterCOBID() function block.so please ask how to troubleshoot and identify the problem in this case. How to troubleshoot and confirm the problem?
Have you used the CANopenRecvEmcy() or CANopenRecvEmcyDev() function blocks to read out the emergency messages ?
Each node on the CANopen network has a unique Node ID (1–127), and the COB-ID for its emergency message is calculated as:
COB-ID = 0x080 + Node ID
Thank you for your reply .
