5.1.10.3 Change Process Values
The status of signal outputs can be changed (forced) for test purposes. Please consider
thereby that the status of a simulated output can change automatically by
·
settings in the telecontrol function
·
running application program (status change by logic operation)
·
the communication (status change in the received message)
It is not possible to set new process values for signal inputs.
Warning
The status change of signal outputs with the plant running can lead to damage to persons and machines.
Ensure that aggregates in the control area of the command output as well as those subsequent aggre-
gates in the process chain are protected and that persons in the vicinity are warned.
·
Select a DO module or an AO module
Signal outputs assigned to the selected I/O module are listed in a table in the status area.
·
Click on the side bar right beside the status area in order to open the control area on the
right side
As long as no signal has been selected, the control area remains inactive.
You can select 1 signal output or several signal outputs of the same type in order to change
their state conjointly. When selecting signal outputs with different type identifications, a notifi-
cation is shown.
Exception with commands: Due to the 1-out-of-n interlocking, with commands only 1 signal
output can be changed simultaneously.
Note
Errors that the target device recognizes upon forcing outputs (for instance by means of internal interlocks,
application parameters, etc.) are recorded in the diagnosis (menu History).
