Protected Operating Mode - WAGO -I/O-SYSTEM 750 Series Manual

18 • 750-655 [AS-Interface master module]
Functional description
The master module is switched to set-up mode by short-circuiting the mode
contacts M1 and M2 for at least five seconds. The yellow "prj mode" LED
illuminates in set-up mode. In set-up mode, all detected slaves, with the
exception of slave zero, are activated. The master module is in normal mode.
Data is exchanged between the master module and all detected slaves
regardless of whether the detected slaves have already been set up.
Note
The AS-Interface master module is supplied from the factory in set-up
mode.

Protected operating mode

The master module is switched from set-up mode to protected mode by short-
circuiting the mode contacts M1 and M2.
Brief short-circuit:
The master module switches from set-up mode to protected mode without
setting up the current actual configuration as a required configuration.
Short-circuiting for longer than five seconds:
The master module switches from set-up mode to protected mode. At the same
time, the actual configuration is stored in the module as a required
configuration.
Note
If a slave with the address zero is detected on the AS-Interface, it will not
be possible to exit the set-up mode.
Note
In protected mode, only those slaves are activated, which have been set up
and the required configuration of which matches the actual values.
Note
In contrast to the set-up mode, in protected mode, data is only exchanged
between the master module and the slaves that have been set-up.
