7 – 166 HEIDENHAIN Technical Manual TNC 426, TNC 430
Module 9260 Receiving and waiting for events
Call the module only in a submit job or spawn job. The module enables a
spawn job or submit job to interrogate or wait for the occurrence of one or
more events. At the same time, the module triggers a change in context.
Markers 4200 to 4202 and 4204 have undefined changes after the module call.
If you transfer the value zero for the event mask, the TNC returns all set events
without deleting them. Otherwise, in a call with a waiting period, the TNC
returns all the requested events and deletes them. For a call without a waiting
period, the TNC returns and deletes the events only if the condition is met.
If the events are OR-gated, the TNC 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:
n
Bit 16: BREAK, cancels a function. Setting and reading is permitted. If you
transmit this event, the TNC cancels access to interfaces and the network!

Bit 17: Reserved, do not use
