1838 HEIDENHAIN Technical Manual iTNC 530 HSCI
Example:
Token in OEM.SYS: PLCEVENTS = PLC:\EVENTS.PEV
Entry in the file EVENTS.PEV: SPAWN_PROC1; KEYCODE==5; $0008
Condition: PLC variable KEYCODE corresponds to W274
The event 8 will be sent to the spawn process SPWAWN_PROC1 after
pressing the Ctrl-E (= 5) key.
If the events are OR-gated, the iTNC returns and deletes only the set events.
You can specify the events to be deleted by calling without a waiting period
and with an OR gate.
Event bits 16 to 31 are reserved for the operating system:
Bit 16: BREAK, cancels a function. Setting and reading is permitted. If you
transmit this event, the iTNC cancels access to interfaces and the network!
Bit 17: Reserved, do not use
Bit 18: Reserved, do not use
Bit 19: QUIT, acknowledgment of a request. Use this bit only in the
immediate context of a request.
Bit 20 to bit 31: Reserved, do not use
