I'm working on a system that has one (1) CR0403, one (1) CR9042, & one (1) CR2033. I'm having trouble implementing heartbeat monitoring. I'd like to be able to indicate on the CR9042 if it loses communications with the CR0403 or if the CR2033 has communications issues.

The attached PDF file shows my CAN parameter settings for the three devices. I haven't had any success getting the CANOPEN_GETGUARDHBERRLIST function block to do anything in the CR0403 program.

Also, if I leave Support DSP301.V4.01 and DSP306 checked on the CR0403 CAN parameter tab I get the red DIA light on the CR2033. If I uncheck this, the CR2033 works fine.

Any suggestions, advice, or examples would be greatly appreciated. Thanks.

You must be using the latest firmware and libraries for the heartbeat to work properly.
firmware: v010203
Can Libs: v10001

The red light on the IO block could be caused by having both the reset and heartbeat consumer activated. Uncheck the reset if you are trying to use heartbeat consumer.
