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.

The execution of part programs or part program blocks in AUTOMATIC or MDA modes is referred to as program

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.

Machine data

Defined conditions can be set via machine data for the program operation or certain implementations of the NC

language scope.

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
