XDIAG parameter
You can use the advance diagnostics parameters to display fault messages in one, two or
three stages. In addition to the fault message output, alarm outputs 1 and 2 are then used.
For this purpose, set the "XDIAG" parameter as described in the following table:
Settings of XDIAG
Message due to
OFF
Advanced diagnostics not activated
On 1
Fault message output for threshold 3 fault messages (one-stage)
On 2 Fault message output for threshold 3 fault messages and alarm output 2 for threshold 2
fault messages (two-stage)
On 3 Fault message output for threshold 3 fault messages and alarm output 2 for threshold 2
fault messages and alarm output 1 for threshold 1 fault messages (three-stage)
Possible settings of the "XDIAG" parameter

Meaning of error codes
1 Monitoring of control deviation
The deviation between the setpoint and the actual value is continuously monitored in the
automatic mode. The fault message for the remaining control deviation is activated
depending on the setting of the "
TIM" parameter, monitoring time for setting the fault
messages and "
LIM" and the response threshold. The fault message is cancelled as soon
as the control deviation drops below the response threshold.
2 Automatic mode monitoring
When the device is not in automatic mode, a fault message is generated if the " FCT"
parameter (function of fault message output) is set correctly. A warning is then sent to the
control system if the device was switched to manual or configuration mode on-site.
3 Binary input BE1 or BE2 active
If the binary input is activated, a fault message is generated when the " FCT" parameter
(function of fault message output) and the "BIN1" parameter (function of binary input 1) are
set correctly. For example, it can be a switch to monitor the packing glands, a temperature
switch or a limit switch (e.g. for pressure).
Binary input 2 (in the optional alarm module) can be configured in a similar manner.
