27.31 Pid out freeze Freezes, or defines a source that can be used to freeze, the
output of the process PID controller. This feature can be
used when, for example, a sensor providing process
feedback must be serviced without stopping the process.
The output of the PID controller is frozen as long as the
selected source is 1.
See also parameter 27.30 Pid ref freeze.
No Process PID controller output not frozen. 0
Freeze Process PID controller output frozen. 1
DI1 Activation of digital input DI1 (as indicated by 02.01 DI
status, bit 0) freezes process PID controller output.
1073742337
DI2 Activation of digital input DI2 (as indicated by 02.01 DI
status, bit 1) freezes process PID controller output.
1073807873
DI3 Activation of digital input DI3 (as indicated by 02.01 DI
status, bit 2) freezes process PID controller output.
1073873409
DI4 Activation of digital input DI4 (as indicated by 02.01 DI
status, bit 3) freezes process PID controller output.
1073938945
DI5 Activation of digital input DI5 (as indicated by 02.01 DI
status, bit 4) freezes process PID controller output.
1074004481

27.34 PID bal ena Selects a source that enables the PID balancing reference
(see parameter 27.35 PID bal ref).
1 = PID balancing reference enabled.
DI1 Digital input DI1 (as indicated by 02.01 DI status, bit 0). 1073742337
