12.3.3 XDIAG parameter
You can use the extended diagnostics parameters to display error 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 Extended diagnostics not activated
On1 Fault message output for threshold 3 error message (maintenance alarm, single-stage)
On2 Fault message output for threshold 3 error messages and alarm output 2 for threshold 2
error messages (maintenance demanded, two-stage)
On3 Fault message output for threshold 3 error messages and alarm output 2 for threshold 2
error messages and alarm output 1 for threshold 1 error messages (maintenance required,
three-stage)
Possible settings of the 'XDIAG' parameter
12.3.4 Meaning of error codes
12.3.4.1 1 Remaining control deviation
The deviation between the setpoint and the actual value is continuously monitored in
"Automatic" mode. The fault message for a remaining control deviation is activated depending
on the setting of the application parameters "
TIM" - monitoring time for setting the fault
messages - and " LIM" - response threshold for the fault message. The fault message is
cancelled as soon as the control deviation drops below the response threshold. This monitoring
function is always active.
12.3.4.2 2 Device not in "Automatic" mode
When the device is not in automatic mode, an error 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.
12.3.4.3 3 Binary input BIN1 or BIN2 active
If the binary input is activated, an error 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.
