I am currently working on a job where i am recieving a 4-20ma signal from a tempreature controller. the signal is steady but the value in the plc is jumping around 10-15%
Processors tried, PM554 eco & pm573-eth
analog modules , AI561 & AX522
its only a problem with external sources, loop powered are ok.
i have tried everything i can think of!
I have used "statistic_real" to average it but its not ideal.
hooked the wires up to a SLC plc & was spot on so problem is back in the plc
its on both current & voltage inputs.
I have been using these plcs for around 4 years now & have only just stumbled across this issue.
Thanks in advance
