The Shared Memory
The shared memory connects the sequence control of the PLC and the
motion functions of the CNC. Both controller systems operate synchronously
for data exchange on the memory and the PLC can take on a master
function. Visualisation systems are also integrated in the communication
process via OPC.

connection of
PLC and CNC
The close link between the CNC and the PLC system now enables you to
carry out complex processes which would not be possible with separate
CNC and PLC controllers. The classic PLC interface enables PLC functions
in NC programs, e.g. the setting and requesting of PLC flags. The
synchronisation of the PLC task with the CNC position control provides
further options:
Click with the right mouse button on the project tree icon of the task in
which the program is to be inserted. (see: Figure 83)
Select Insert/Program instance in the context menu.
Enter an instance name for the program in the
Program instance
field.
Set the required program in the
Program type
list box.
Confirm the dialog with OK.
There are no waiting times or communication overhead.
The PLC can monitor all actions of the CNC
The CNC output setpoints via the PLC.
The PLC can specify the CNC management sizes in the position control
cycle
