Hoping for some guidance with a issue I'm having with the RevPi running Node-Red.
Currently I have the RevPi communicating to a Allen Bradley Compact Logix PLC via Ethernet connection, and have setup a timestamp in milliseconds to constantly update to the PLC.
The problem is at regular time intervals, the PLC tag stops updating for about 400ms. While in top or htop, i can see that the instance for Node-Red spikes the CPU quite high, and these spike correlate with the comms 'stutter' I'm experiencing at the other end.
Has anyone experienced something like this before? I'm not sure what the root cause of the issue is, testing so far hasn't yielded any obvious results.
