I am trying to program an analogue output on a Siemens S7-1500 unit from a 4-20ma sourced analogue input scaled over 0-250 degrees.
The analogue input will have an adjustable setting in the software for when the alarm status should occur and at this point I want the analogue alarm output to start to process at 4ma, at 5 degrees above the initial set point I want the analogue output value to be 20ma
I have no idea how to do this so any help from people is greatly appreciated and advice on which analogue output card to use would be helpful.
