Use IO Status in Program in Automation Builder
I am working in Automation builder 2.0, PM564-RP-ETH-AC CPU and AI523 IO modules.
Is it possible to use hardware module status in programming i.e underflow status on analog input can be used in programming to generate alarm or event?
Just like we can do it in Control Builder with 800 series hardware.
It is not the same as for CBM. I can advise two possibilities, may be other methods exist too.
Look in help for AI523 -> Diagnosis.
For underflow it is class 4, Error Identifier 7, for corresponding module No and Channel No. Then for example you can use DIAG_GET function block.
for the channel value you should look if it is in the range.
For eample for 4-20 mA channel, the limits are from 0 to 27648. All the values outside that range indicate under/overflow. You have to create own code for that supervision.
Look in the help AI523 -> Measuring Ranges
