Hello friends
I have new project
Air compressor the company want to upgrade it to work with PLC and HMI
The compressor work with micro processor and the micro processor
Is damaged the problem in 2 solenoid open the air gate and if the solenoid coil is broken the micro processor stop the machine and make alarm
The solenoid coil is normal only 2 wire 24v dc
How the micro processor feel the broken coil and if the wire is cut
And the owner need in the upgrade this feature
How can I make the plc feel the coil if broken or damaged
I will use plc s7 200 with out put relay
I think the micro processor measure the coil resistance
But in the plc ? what we will use ?
Sorry about my little English
And I am wait to answers me
