9.5.3 PV Scale
● Units
The engineering units code used for PID process variable.
● Upper Range (EU100)
Upper limit value
● Lower Range (EU0)
Lower limit value
9.5.4 Configuration - PID Options
This setup page consists of both Control Options and Status Options for PID block. For
each parameter, it is enabled/disabled if it is checked/unchecked.

Bypass Enable
The normal control algorithm may be bypassed through the BYPASS parameter. When
bypass is set, the setpoint value (in percent) will be directly transferred to the output. To
prevent a bump on transfer to/from bypass, the setpoint will automatically be initialized to
the output value or process variable, respectively, and the path broken flag will be set for
one execution. BYPASS is not permitted unless the BYPASS ENABLED option is set.
SP-PV Track in Man
Permits the setpoint to track the process variable when the target mode of the block is Man.
SP-PV Track in ROut
Permits the setpoint to track the process variable when the actual mode of the block is
ROut.
