16#0B Error Read_Var Block Facing Communication Delay PLC M580

[Sohan_02]

Dear Schneider Team,

We are facing communication delay in Nom Cards and error 16#0B (No processor system resources) how we can minimize this error.

Good day,

Could you please provide more information/screencap on how you are calling the Read_VAR block? Also which specific M580 you are using and if the NOM card is in the main rack or on RIO rack. 

Regards,

Redundant HSBY Processor module M580 - Level 2 - Remote(BMEH582040)

We have a total of 5 nodes in our M580 PLC system. Node 4 is the RIO (Remote I/O) cabinet. We are not seeing the 16#0B communication delay error on Node 1, but Nodes 2 to 5 are showing this error.

We are not facing any communication break issues, but we are experiencing delays in data updates — values are updating only after 2 to 3 minutes.

We attempted to power cycle the main processor cards to clear any buffer issues, but the 16#0B (No System Resources error) is still appearing on Nodes 2 to 5.
Node 1 is working normally without any delays. We connect only one device to each Channel port — there is no daisy-chaining or multiple devices per port. Please find attached IO Cards Details
