S800 AI810 Analog Input module
One of the customer place, they are using S800 IO module AI810 for analog signals. All analog signals are connected with 0-20mA from the source. The problem is when wire break happens there is no indication in the module signal status. it show helathy. Any solution to identify the wire break or signal missing.
If it is 4-20 mA, we will get underflow indication. but for 0-20mA we get helathy status and 0 value. Need Expert ideas to overcome this problem

NO. You would have to be a magician to detect the diference between zero milli amps from a broken wire and zero milliamps from a working circuit. Thats why we use 4-20 mA.
