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
• "Address extension" parameter
• "Value" parameter
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 for auxiliary function transfer from NC channel:
DB21, ... DBB58 - DBB67
• Transferred M and S functions:
DB21, ... DBB68 - DBB112
• Transferred T, D and DL functions:
DB21, ... DBB116 - DBB136
• Transferred H and F functions:
DB21, ... DBB140 - DBB190
• Decoded M signals (M0 - M99):
DB21, ... DBB194 - DBB206 (dynamic M functions)
