6.3.3 User-defined error messages
In the programmable variant of the prepared solution, users can program their own error
messages in addition to the standard errors. To do this, proceed as follows:
1. Create a new network by copying and pasting one of the networks from the
UserErrors(PRG) POU.
2. Rename the copied FB FWM.
3. Link the bExecute input from the instanced FB FWM to the boolean variable to be monitored.
In order for errors to be resolved correctly, the boolean variable to be monitored may only be
TRUE for the specific machine state. The trigger signal must be pending for at least 5 ms.
You can safeguard this by using a pulse timer, for example (FB TP).
4. Set the required error number at the wFaultNumber input of the instanced FB FWM. Only
error numbers from 508…999 may be used. Error numbers below 508 are already in use.
Input FB FWM
Name Data type Value/Meaning
Error number for the user error message
wFaultNumber
WORD
508 … 999 Error number
5. You can assign an error message (text message) to the set error number in the ErrorCode
(ENUM) data type (see Chapter 6.3.4).
6. Set the required error response at the byTypeOfFault input. You can select from the
following options:
Input FB FWM
Name Data type Value/Meaning
Selection of response to user error message
0 TRIP
1 Message
2 Warning
3 Off (no response)
byTypeOfFault
BYTE
4 Fail QSP
7. Link the wActFaultNumber input to the g_wActFault global variable.
Input FB FWM
Name Data type Value/Meaning
wActFaultNumber
WORD
Error channel for the system; link this variable to the g_wActFault
global variable.
Note!
The wActFaultNumber input of the FB FWM acts as an error channel for communication
with the internal "FailManager" and must be linked to the g_wActFault global error channel
variable.
