2.6 2.6 Auxiliary function output to the PLC
Function
On output of an auxiliary function to the PLC, the following signals and values are passed to
the NC/PLC interface:
• Change signals
• Parameter: "Address extension"
• Parameter: "Value"
NC/PLC interface
The change signals and values of the auxiliary functions are within the following data range
in the NC/PLC interface:
• Change signals on auxiliary function transfer from NC channel
DB21, ... DBB58 – DBB67
• Transferred M and S functions
DB21, ... DBB68 – DBB112
• Transferred T/D/DL functions
DB21, ... DBB116 – DBB136
• Transferred T/D/DL functions
DB21, ... DBB140 – DBB190
• Decoded M signals (M0 - M99)
DB21, ... DBB194 – DBB206

Syntax
An auxiliary function is programmed in a part program block with the following syntax:
< type > [ < address extension > = ] < value >
Address expansion
If no address extension is programmed, address extension = 0 is implicitly set.
