Definition of an auxiliary function
An auxiliary function is defined by the following parameters:
• Type, address extension, and value
The 3 parameters are output to the NC/PLC interface.
• Output behavior
The auxiliary-function-specific output behavior defines for how long an auxiliary function
is output to the NC/PLC interface and when it is output relative to the traverse movement
programmed in the same parts program block.
• Group assignment
An auxiliary function can be assigned to a particular auxiliary function group. The output
behavior can be defined separately for each auxiliary function group. This becomes
active if no auxiliary-function-specific output behavior has been defined. Group
membership also affects output of an auxiliary function after block search.
For more detailed information on auxiliary function output to the NC/PLC interface, see:
