    Thanks I did, but don't know if it's helping me. Can anyone explain the SCL2 function? If I understood corectly there are three parameter words, P1 (offset which is in my case zero), P1+1 (X number of increments - in my case the full scale is 4000 BCD = 0FA0 HEX is what I should enter) and P1+2 (Y full scale conductivity - for exemple 1000 mS/cm in BCD that means I should enter 1000 and not 03E8). To conclude should the last parameter word be entered in BCD or in HEX like two first words?

    Hello people, I'm a novice to PLC programming so be aware that some questions might be silly beyond any limits. I cannot find the explication for this instruction (actually for the parameter word P1). I can see it's formed of 4 words but which one is what. I need it to convert the 4-20mA signal into 4000 increments which will measure the conductivity/concentration. General idea was that Source word is conductivity (in increments) and result word is concentration (two of them, separate, one for acid and the other for alkali).
