Check machine status on PLC

[evilaid 0]

Hey everyone,

I havent touch a PLC for 15 year and then it was Mitsubishi. 

today we looking at a sscenario where we have a bunch of machines with different ages of PLC's, Simens and Mitsubishi.. Might  be that one or two has a network inteface.  What we would like to achive is just reading the state of the machine if it runnning or not. Is there as easy "generall " way of doing this? 

What i would have liked is to use a something similair to Arduino board connected to PLC for the sake of reading if the machine is running or not?

 

Thanks

Ed

You could use an Arduino and connect a digital output from each of the PLC's to indicate the state. However I would recommend selecting a more industrialized version for production environment, I think that RS sells some that looks more or less like a small PLC... However, I'm not sure I fully understand your question?
