====== Alarm messages======

Alarm messages can be signaled to MK|Ware as BOOL, WORD or DWORD. For this purpose, all alarm messages must be mapped in the following structure (table or CSV):

===== Variable definition=====

|<100% 20% 45% 10% 15%>|
|^Column ^Description ^Type ^Required/Std.|
|^Number                        |Error message number in the visualization                                              |INT                |Yes|
|^Text                          |Static error message as text                                                           |STRING             |Yes|
|^Bit number                    |Starts at 0. Required for error message linking with WORD or DWORD, otherwise 0.       |INT                |Required for WORD/DWORD, otherwise 0.|
|^PLC variable name/address     |The name or address of the variable that indicates the error.                          |BOOL/WORD/DWORD    |Yes|
|^Description                   |Details of the error message                                                           |STRING             |Optional|
|^Corrective action             |Possible corrective actions.                                                           |STRING             |Optional|

The error messages are imported into the [[en:software:mksupervisor:strukturbaum:maschine:stoermeldungen_verwalten:start|MKSupervisor]] once and linked to the PLC variables.
Any number of alarm messages can be active at the same time. All variables are monitored and recorded independently of each other.

===== Error messages (BOOL) =====
There is a corresponding BOOL variable in the PLC for each error message. The breakdown shown above defines which BOOL variable corresponds to which fault.
The error message recording is triggered by a rising flank and switched off by a falling flank.

===== Error messages (WORD/DWORD) =====
16 error messages are displayed per WORD and 32 per DWORD. The respective bit position of the error in the WORD/DWORD is defined in the zero-based bit number column in the breakdown shown above. It also defines which WORD/DWORD contains which error.
The error is triggered by the rising flank of the associated bit and switched off by the falling flank of the associated bit.
