The dialogs for PLC error messages can be determined by the manufacturer of the machine. Please
contact HEIDENHAIN about this. The standard version has dialogs with the reserved designations
"PLC: ERROR 0" to "PLC: ERROR 99". These PLC error messages can be activated by the PLC
markers M2924 to M3023.
The error messages can be canceled either by pressing the CE key or by resetting the appropriate
markers.
If several PLC error messages are activated simultaneously, they can be read out one after another
by pressing the CE key.
If the program run is to be stopped on output of a PLC error message, this must be explicitly
programmed in the PLC program (NC STOP).
In order to show a PLC error message as a flashing message, the marker M2815 must also be set.
If marker M2815 is set, but none of the 100 PLC error messages is activated, then the flashing error
message "EMERGENCY STOP PLC" will be displayed.
If, for some reason, the display of the PLC error message is not wanted in the field under the
operating-mode display, the message can also be displayed in the PLC window.
