Hi, i'm still new to PLC programming especially related to analog type.
i understand that there is scaling involved. my question is say for a
4-20mA input and my output is -100 to 200 respectively (i know how to
do 0 to 200), how do i put the negative portion onto the PLC program
and show the result onto a HMI ???
thanx
