2.7 Program operation mode
PLC, MD, operation
The execution of part programs can be controlled via the HMI in many ways using PLC
inputs, machine data settings and operator inputs.
Definition
The execution of part programs or part program blocks in AUTOMATIC or MDA modes is
referred to as program operation.
Channel control
Every channel can be manipulated by means of interface signals from the PLC. The control
is exercised via mode groupspecific or channelspecific interface signals. An overview of
these signals is given under data lists in this Description of Functions.
Status messages
Each channel reports its current program operation status to the PLC with interface signals.
These signals are, in turn, divided up into mode groupspecific and channelspecific signals.
2.7.1 Initial settings
Machine data
Defined conditions can be set via machine data for the program operation or certain
implementations of the NC language scope.
MD settings
Initial settings
Initial settings can be programmed in channelspecific machine data for each channel. These
initial settings affect, for example, G groups and auxiliary function output.
Auxiliary function output
The timing for output of auxiliary functions can be predefined via machine data
AUXFU_x_SYNC_TYPE (MD22200, 22210, 22220, 22230, 22240, 22250, 22260), (output
timing for M, S, T, H, F, D, E functions). For further information, see:
