5.3 Record Select mode
Record Select mode In the Record Select mode the SPC200 is controlled by a
higher−order PLC/IPC. The controlling PLC/IPC sends posiĆ
tioning tasks in the form of binary−coded record numbers
via digital I/Os to the SPC200. The SPC200 then processes
the desired NC record and waits for the next positioning
task. If controlled by an I/O module, NC records 0...31 of the
starting programs can be accessed via 5 digital inputs. With
control via a field bus, the NC records 0...999 are available.
As the sequence of the NC programs is controlled by a higher−
order PLC/IPC, NC commands, which serve for sequence conĆ
trol, are not permitted in this operating mode.
Only the following NC commands are supported:
