This section describes parameterization of the PID and cascade controllers.
For all control settings from PID controllers a reference is made on the same page
for the loop controller; for all control settings for cascade controllers on the same
page for the cascade controller. All physical units were left out for this reason.
Furthermore, the outputs Control output clg und Control output htg for humidity
controllers are used for dehumidification or humidification.
7.1 Loop controller
7.1.1 General
The details page for PID controllers can be reached multiple ways, including:
– Main Index > Unit > Loop controllers > Controller-Element
or
– Main Index > Unit > Elementgruppe > Element > Controller
– Main Index > Unit > Loop controllers > Supply fan
or
– Main Index > Unit > Fan control > Supply fan > Controller
Parameter Range Function
Control output 0…100 [%] Present output for the controller.
Present value Present actual value (input value) for the control-
ler.
Setpoint Present setpoint for the controller.
Enable.
− Passive
− Active
Enable controller:
− Controller disabled.
− Controller enabled.
Fault
− Passive
− Active
Controller fault status, e.g. faulty sensor signal:
− No error.
− Error pending. Does not trigger an event,
since the cause of a control fault must be re-
corded separately (e.g. sensor fault).
Status − GESP
− UL
− LL
− REG
− Y-NV
− UDEF
− Blocked: Controller not enabled or set to out
of service.
− Control output = High limit.
− Control output = Low limit.
− Control mode.
− Direct intervention on hardware output is en-
abled (e.g. manual via HMI or frost).
− Undefined.
