4.1 Defining auxiliary functions
Basic logic functions: Auxiliary Function Output to PLC (H2)
Function Manual, 11/2006, 6FC5397-0BP10-2BA0
61
• The auxiliary functions M50, M51 (auxiliary function group 12) and M52, M53 (auxiliary
function group 13) should have the following output behavior:
– Output duration one OB1 cycle (normal acknowledgment)
– Output prior to motion
Parameterization of the machine data
The machine data are parameterized by appropriate programming within a part program.
