communication error variables for NX/NJ datalink using CJ areas

[CX_Luigi 1]

getting two NX/NJ plc to communicate through CIP datalink, i can check  _EIP_TargetNodeErr[<IP node address>] and _EIP_RegTargetSta[<IP node address>] for communication problems. However this does not work when the datalink is done through CJ areas. I can get around it in program, but I would better like using an internal variable like the ones above. So far I didn't found anything in the documentation, are such flags existing and available as system variables?

Thanks

Are you referring to using a CJ1W-EIP21 card or using the CJ areas for FINS?

CJ area for FINS

No system variables exist for communication that isn't cyclic and managed by the system itself. FINS, Modbus, MQTT, and Socket Services all fall in this category.

Got it, thanks

NX CPU's want to communicate with 8 bites or more if you make them smaller they will error out with CJM cpu's omron has plenty manuals for setting up communication between these 2
