6.6 Error messages
Under certain conditions error messages from the NC or the PLC will be displayed on the screen
under the display for the operating mode. Non-flashing error messages can be cancelled with the
CE-key. In the event of a flashing error message the machine must be switched off and the fault
corrected. If a non-flashing error message is displayed on the screen, marker M2190 will be set.
The manufacturer of the machine determines the conditions under which the PLC will produce error
messages. Up to 100 different PLC error messages can be generated.
The dialogues for PLC error messages can be determined by the manufacturer of the machine.
Please contact HEIDENHAIN about this. The standard version has dialogues 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 cancelled 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.
