(enters the ON/OFF command as well as also the setpoint). A changeover is only made into
the automatic mode after the set-up has been completed. In the automatic mode, the control
(open-loop) of the machines and production processes are handled by a higher-level control
system (e.g. PLC). This operation is maintained until it is necessary to again load and unload
the machine or feed new material into the machine or production process.
In the SINAMICS G120, indexed parameters P0700 or P1000 and BICO parameters P0810
and P0811 are used to changeover (toggle between) the manual/automatic modes. The
command source is defined using P0700 and the setpoint source is defined using P1000,
whereby index 0 (P0700[0] and P1000[0]) defines the automatic mode and index 1 (P0700[1]
and P1000[1]) the manual mode. BICO parameters P0810 and P0811 are used to
changeover (toggle between) the automatic and manual modes. These BICO parameters
can be controlled from any control source. In so doing, in addition to P0700 and P1000, also
all of the other CDS parameters are changed over (manual/automatic changeover is
generalized as a CDS changeover).
