6.14 Passivating PC objects
Introduction
With the "Passivate" function, a PC object is temporarily excluded from the monitoring during
process control.
Overview
A PC object is passivated by the following operator actions:
● Operator actions in the faceplate in the "Maintenance" view
The operator actions are stored retentively and are retained even if there is a complete
download to the OS station.
You can find additional information on this in the section ""Maintenance" view (Page 146)".
● Disabling/enabling process control
If the process control of a monitored OS station is deactivated, its PC object is automatically
set to passivated.
As soon as this OS station is restarted, the passivation is canceled again.
Available
This function is available on all IPC/PC stations.
Display
If a PC object is passivated, "Passivated" is displayed as the maintenance state in the block
icon and faceplate.
No group alarm is displayed in the maintenance group display of the PC object.
Messages
If a PC object is passivated by an operator input in the faceplate, an operator message is
generated.
All messages pending for this PC object are acknowledged automatically when the PC object
is passivated.
As long as the PC object is passivated, no new messages are generated for this PC object.
Any pending events are signaled when the PC object is depassivated.
