6.2 Cyclic parametrising in parametrising mode
In parametrising mode the FPC can be used to transmit one
parameter at a time in the cyclic I/O data.
The PLC enters the request in the output data and waits until
the CMAX has entered a response in the input data. This proĆ
cess takes several bus cycles.

Tab. 6/6: FPC in the cyclic I/O data
In the first byte, the control byte CCON is transmitted which
controls the operating mode and controller enable. The CMAX
responds with the SCON status byte.
Please note that the CCON.STOP bit must not be set since the
CMAX cannot switch to operation enabled" status in para−
metrising mode.
CCON.STOP = 1 leads to a warning.
