The maximum number of BL20-E-1SWIRE modules per BL20 station is restricted by:
the number of process data, diagnostics, parameter and configuration bytes of the BL20-E-
1SWIRE:
– 8 byte input data
– 8 byte output data
– 24 byte parameter data
– 8 byte diagnostics data.
and the field bus system used.
From version VN 01-04, BL20-E-1SWIRE can be run in conformance with the Moeller SmartWire stan-
dard. For this the ”Moeller Conformance” function has been implemented. See s. S. 458, Moeller
SWIRE conformance criteria.
