3.8 Subroutine 32 - PLC_INI (PLC initialization)
Purpose
Subroutine 32 is executed at the first PLC cycle (SM0.1). This subroutine set NCK interface
signals according to the machine settings defined by PLC machine data. In this subroutine,
the following interface signals are set:
● DB3200.DBX6.7: feed override of the NCK channel becomes active
● DB380x.DBX1.5: measurement system 1 of the axes is active
● DB380x.DBX1.7: feed override of the axes is active
● DB1700.DBX1.3: active ROV
At the end of this subroutine, subroutine 31 (PLC_ini_USR_ini) is automatically called. You
can program the initialization of customer PLC project in the subroutine 31.
