Priority of PLC error
messages
You can enter a priority between 0 and 2 for the PLC error messages defined
in the PET table. Priority 0 (error) is the highest priority, followed by priority 1
(warning) and priority 2 (info). PLC error messages triggering an EMERGENCY
STOP receive the highest priority (independent of the priority from the PET
table). Therefore, these error messages always appear at the first position in
the error list. The error message External EMERGENCY STOP has a lower
priority, but still a higher priority than the top PLC priority. This means that PLC
error messages triggering an emergency stop always appear at the first
position in the error list. They are followed by External EMERGENCY STOP and
then by further PLC error messages, depending on their priority.
Error text file Error texts are defined directly in the PET table (max. 32 characters; not
language-sensitive) or in the error text file. In the error text file, you define the
error text to be displayed as well as the information on the cause of error and
corrective action.
Error text files are language-sensitive. The path for the error text file is
permanently defined: %OEM%\plc\language\en (or another language
abbreviation).
In MP_System/DisplaySettings/CfgDisplayLanguage/plcErrorLanguage, you
define the language to be used.
You define the name of the error text files in MP_errorText.

The error texts can be specified in the following manners:
• Direct entry of the error text (max. 32 characters)
• Line number of the PLC error text file (# <line no.>) defined in
MP_errorText.
MARKER
The PLC error message can be activated without module call by setting the

activated through Module 9085. Enter the symbolic name of the marker to
be set.
