(1) Enabled operations
This area shows all operations for which special operator authorizations are assigned. They
depend on the configuration in the engineering system (ES) that applies to this block.
Symbols for enabled operations:
● Green check mark: The OS operator can control this parameter
● Gray check mark: the OS operator cannot control this parameter at this time due to the
process
● Red cross: The OS operator cannot control this parameter due to the configured AS
operator permissions (OS_Perm or OS1Perm)
(2) Actual value limits (Sipart alarm module)
The limits displayed here are the limits of the optional Sipart PS2 PA alarm module. You cannot
change the values in the faceplate. Depending on the configuration of the alarm module ( Afct
input), the alarm limits (A1, A2) are shown as alarm high/low, alarm/warning high or alarm/
warning low. The associated messages in WinCC are triggered by setting the inputs A1Act and
A2Act.
(3) Limit and monitoring time manipulated variable difference (Sipart)
This area displays and may allow you to change the limit for the maximum manipulated variable
difference (LIM) and the monitoring time (TIM) which must deviate from the manipulated
variable before a fault message is triggered in the device. In the event of a limit violation, the
general message "Sipart error" is output in WinCC.
If the limits LIM and TIM are not to be displayed, the Feature2.Bit3 must be set to FALSE.
(4) Manipulated variable difference limits
In this area, you can enter the limits for the manipulated variable error. Refer to the "Changing
values" section in the APL Online Help.
You can change the following limits:
● "H alarm": High alarm
● "Hysteresis"
● "L alarm": Low alarm
(5) Readback value limits (MV)
In this area, you can enter the limits for the readback value (position feedback). Refer to the
"Changing values" section in the APL Online Help.
You can change the following limits:
● "H warning": High warning
● "Hysteresis"
● "L warning": Low warning
