Analog Output (OP)
The output (or “OP”) can be used to read and write an analog value. It can only
be changed by an operator if the mode is set to MANUAL (see “Analog Mode
(MD)” on page 130). It is represented as a percentage value and is often used to
represent the value ranges that an operator can control for a given point or the
output of a control loop.
For example, in defining the OP of an analog point, you might define a
temperature range of 0 to 550 degrees celsius that an operator can control for a
furnace.
