1.4 Operating modes of the SPC200
The SPC200 offers suitable operating modes for the different
applications. The functions of the digital inputs and outputs
of the SPC200 depend on the operating mode set. The followĆ
ing operating modes are available:
ć Start/Stop mode
ć Record Select mode
Start/stop mode In Start/stop mode the SPC200 can control simple positionĆ
ing tasks independently or together with a higher−order
PLC/IPC. Freely programmable inputs and outputs are availĆ
able in this operating mode.
You can start and stop positioning programs either with the
control panel, a handheld or a higher−order PLC/IPC.
The command Programmed Stop (M00) is available for loose
coupling with a higher−order PLC/IPC. With this command
you can synchronize the program sequence of the SPC200,
e.g. with externally controlled processes.
Record Select mode The Record Select operating mode supports the close
coupling of the SPC200 with a higher−order PLC/IPC. The
complete sequence control here is carried out by the conĆ
trolling PLC/IPC. This controller passes positioning tasks in
the form of record numbers via digital I/Os to the SPC200.
When the I/O module is used, the NC records 0...31 of the
active program can be accessed via 5 digital inputs. These
records usually contain positioning tasks. The PLC/IPC can
therefore access freely up to 32 positions per axis. The maxiĆ
mum permitted number of NC records (1000 NC records) can
be accessed via field bus modules.
