remains ON). Set the MOD switch OFF again, remove slave 0, and set MOD
back ON to enter Protected Mode.
A change from Configuration Mode to Protected Mode causes a restart of the
AS-Interface master, starting with the off-line phase. As a result, all slaves will
temporarily be reset.
Setup mode is not defined by the AS-Interface Specification. In Setup Mode
the CQM1-ARM21 does not comply with the requirements of an AS-Interface
master in the sense that I/O data exchange with the Host PLC system is
partially suspended. Instead, the user can issue commands via the PLC to be
processed by the master, in order to build up the configuration from scratch
without additional configuration tools.
