TNC 406/TNC 306 1 Creating user cycles 9-5
MP7240 Inhibit program input if [program number] = [user cycle number in
EPROM].
Input value: 0 or 1
0 = Inhibit
1 = Do not inhibit
MP7250 Difference between Q-parameter number for "DLG-CALL" and "DLG-DEF" block
in user cycles.
Input range: 0 to 50
MP7251 Number of global Q parameters transferred from user cycle to calling program.
Input range: 0 to 100
User cycles stored in the PLC EPROM can be inhibited in the PLC program via markers M2240 to
M2271. It is then not possible to define inhibited cycles in NC programs.
If programs with definitions of inhibited user cycles are transferred to the control, an error message
"PGM 999999.. UNAVAILABLE=..." is generated in the transferred program and the program cannot
be executed.
