SIPART PS2 HART
7.1 SipPS2HA
(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
control permissions (OS_Perm or OS1Perm).
(2) Monitoring
In this area, you change parameters and therefore influence the control valve. Refer to the
"Changing values" section in the APL Online Help.
You can influence the following parameters:
● "Control": Monitoring time during opening and closing of the control valve (dynamic)
● "End position": Monitoring time of the end position of the control valve (static)
Enable monitoring
You can enable monitoring by selecting the check box (☑)
For more information, refer to the "Monitoring feedbacks" section in the APL Online Help.
(3) Monitoring auxiliary valve
As under (2) Monitoring, but only visible when there is an auxiliary valve. Only one common
monitoring time can be entered for dynamic and static monitoring.
(4) Settings
● MV = Rbk in tracking mode: Correction is performed with the position feedback Rbk instead
of the MV_Trk tracking value. The switchover from "Track manipulated variable"
(MV_TrkOn = 1) to "Do not track manipulated variable" is bumpless (MV_TrkOn = 0).
Set MV_TrkRbk parameter.
● MV = External MV: Bumpless switchover of the manipulated variable for manipulated
variable switchover from external to internal. The internal manipulated variable is tracked to
the external one.
Set MV_TrkExt parameter.
(5) Read/write configuration data
This area lets you read all configuration data from the Sipart PS2, or transfer all configuration
data from the block to Sipart PS2.
