8/95 TNC 360 3 Calling OEM Cycles 9-9
3.2 Calls in an ISO program
In an ISO program, OEM cycles are not called via a G- function but via key "D" and the cycle number
(e.g. D88).
The individual parameters are input via the numeric keyboard and entered with ENT.
In the case of a "DEF-active" OEM-cycle, the cycle is effective immediately after definition. Once
defined, a "CALL-active" OEM-cycle can be called and hence activated either via G79 or M99.
