Configuration If the PLC configuration check is activated, the configuration stored in the BL20-E-1SWIRE
is compared with the SET configuration stored in the PLC.
active The configuration stored in BL20-E-1SWIRE is compared with the SET
configuration stored in the PLC. Only SWIRE slaves in the SWIRE bus are
accepted that have a device ID completely matching the SET configu-
ration.
inactive All slaves are mapped in 4Bit INPUT/ 4Bit OUTPUT without checking
the device ID.

Configuration check
Line or slave-oriented configuration check (without function if MC = 1)
line oriented If the PLC configuration check is activated, data exchange is only
started if the configuration stored in the BL20-E-1SWIRE fully matches
the SET configuration stored in the PLC. Modifying the bus during
operation causes the system to be aborted.
slave oriented If the PLC configuration check is activated, data exchange is started
with all SWIRE slaves that match the SET configuration stored in the
PLC. The SWIRE slaves that do not match the SET configuration stored
in the PLC do not perform any data exchange.
MC Moeller conformance (from version VN 01-04)
Behavior of the BL20-E-1SWIRE in accordance with SWIRE Conformance criteria.
inactive Default behavior
active The BL20-E-1SWIRE master responds according to the Moeller SWIRE
Conformance criteria.

. As soon as only one slave on the bus sets its error bit, this
is indicated as a group error depending on the parameter setting.
active Group diagnostics is activated
inactive Group diagnostics is not activated
PKZ
INFO
PKZ error field
Activate slave diagnostics info field PKZ
ERR
Sx . As soon as a slave on the bus clears its PKZ
bit, this is indicated as an individual error depending on the parameter setting.
