Hello,
I have a JZ20-R16 plc and a Aplisens 4-20 mA level transducer. I do linearization in ladder to get the correct level value in meters. Depending on the level the plc starts and stops a pump, and it all works greate. Start and stop levels are input by the user from keypad, also the max value of the transducer.
Everything works ok, the problem is with displaying current level on lcd. Right after linearization i copy the value to MI3 that is set to be shown on the "main" screen. It is displayed but the readout is jumping around/changing very quickly (level is constant), numbers get blurry and they are unreadable. Tried this on 2 plcs and 2 transducers with the same result. I've seen this working but can't find any reason for this behavior. Maybe it's reading the value to often?
Please help me. Any advice will be appreciated.
