Simulation of actual value
You can activate the actual value simulation in this tab and also define the actual value to be
simulated and its quality and status. The following feedback values are available:
●
Setpoint
●
Actual value
●
Setpoint deviation
●
Checkback bits in the checkback field.
Changes become effective as soon as the Transfer button is pressed.
Simulation of device status
You can activate the simulation of device status in this tab and can then select the
diagnostics messages to be simulated. It concerns the content of the "DIAGNOSTICS
physical block parameters" that generates different diagnostics messages depending on
whether the condensed status has been activated or deactivated. Changes become effective
as soon as the Transfer button is pressed.
Simulation of device diagnostics 1
You can activate the simulation of device diagnostics in this tab. It is applicable for device
diagnostics 1 and 2.
You can then select the desired diagnostics events in the simulation of device diagnostics 1,
and use device diagnostics 1 and message text to obtain the feedback indicating that the
corresponding event has been triggered in the device. Changes become effective as soon as
the Transfer button is pressed.
Simulation of device diagnostics 2
You can activate the simulation of device diagnostics in this tab. It is applicable for device
diagnostics 2 and 1. You can then select the desired diagnostics events in the simulation of
device diagnostics 2, and use device diagnostics 2 and message text to obtain the feedback
indicating that the corresponding event has been triggered in the device. Changes become
effective as soon as the Transfer button is pressed.
11.2.2.8
Partial stroke test (PST)
Availability
This menu item is available only if the advanced diagnostics has been activated in the
parameter list in advance. You can then activate and parameterize the partial stroke test.
