Addressing in set-up mode

AS-Interface systems on the master module can be commissioned with the
WAGO-I/O-CHECK 2 commissioning tool.
The procedure is described in Chapter Fehler! Verweisquelle konnte nicht
gefunden werden. "Fehler! Verweisquelle konnte nicht gefunden
werden.".
Commissioning can also be carried out using an addressing unit.

Addressing in the case of configuration errors

2.1.1.6.5.1

Automatic addressing

One of the great advantages of the AS-Interface is the automatic address
programming. If a slave fails due to a defect, it can be replaced by a physically
identical slave with the address zero. The master module detects this and
automatically addresses the new slave with the address of the defective slave.
The following requirements must be satisfied for automatic programming:
• The master module must be in protected mode.
• The enable flag "Auto_prog" must be set.
• Only one of the set-up slaves must be undetected.
• The new slave must have the same configuration data as the missing slave.
When these conditions are satisfied, the master module indicates this with the
"prg enable" LED. If a slave is then detected with the address zero, it will
automatically be reprogrammed with the address of the missing slave.
The "Auto_prog" flag for automatic programming can be switched on and off
with the WAGO-I/O-CHECK 2 commissioning tool.
Note
Only slaves with the address zero can be re-addressed by the master
module.
Note
Automatic address programming is not carried out if the two slaves have
different configuration data, i.e. are not physically identical from the AS-
Interface side.
