ORSO2001 Posted August 19, 2019 Report Share Posted August 19, 2019 Dears, I am using the module UIS-WCB1; I need to use the two analog input for a 4-20 mA range, with the output value between 0 to 16383 ; at the moment I donpt have the sensors the the inputs are "free"; in this case I have the status of 0x10, that is ok, but also I have a value of 308 in both inputs...exist a way to define, directly, a value when a "problem" is present?..or I have to store the input value in a tag and, checking the value of the status, forse a value in case of faulty? thanks Quote Link to comment Share on other sites More sharing options...
MVP 2021 Ausman Posted August 19, 2019 MVP 2021 Report Share Posted August 19, 2019 Orso, I think I use something like you are proposing. In my analogue instances there is always some sort of minor variation going on. I have code that recognises something sitting at a constant reading for a given time, and if this happens I then initiate a power reset on that sensor circuit. This came about because I have had occasional instances where a power disturbance has upset sensors somehow and they lock up. They still output, but nothing is changing and the process is sent completely astray. It is set as a count system so that if it repeats the reset a few times in succession it throws an error. cheers, Aus Quote Link to comment Share on other sites More sharing options...
