TNC 407/TNC 415/TNC 425 1 Creating OEM-cycles 01.98
In the NC program, when defining the OEM-cycles created with dialog support, Q parameters are
assigned specified input values. The Q-parameter numbers are automatically generated by the TNC.
In order to prevent the same Q-parameter numbers being generated for "DLG-DEF" cycles and "DLG-
CALL" cycles, the difference between Q-parameter numbers can be specified for "DLG-CALL" and
"DLG-DEF" blocks.
In the case of a "DLG-CALL" block, the input values of the OEM-cycles are assigned in ascending
order of magnitude to the Q parameters Q1 to Q14. For the "DLG-DEF" block, the input values are
assigned to Q parameters Q[1 + MP7250] to Q[14 + MP7250].
Example for MP7250 = 30

MP7251 determines whether the values of the Q parameters which are changed in the OEM-cycles
by calculation or assignment are globally transferred to the called program (e.g. in the case of
"nesting" of OEM-cycles).
With machine parameter MP7251, the range of Q parameters from Q[100 - MP7251] to Q99 is
defined as "global".
The operation of global and local Q parameters may be shown by reference to following example:
MP7251 = 40
Q [100 – 40] = Q60 =>
Q60 to Q99 are global Q parameters and
Q1 to Q59 are local Q parameters
MP7251 = 40 MP7251 < 40
Q1 Q60=global Q1 Q60=local
