Function principle
BL67 electronic modules are plugged into
the purely passive base modules which are
needed for connection of field devices.
Maintenance is significantly facilitated due
to separation of the connection level from
the module electronics. Flexibility is enhan-
ced because the base modules provide a
choice of various connection technologies.
The electronic modules are completely in-
dependent of the type of higher level field
bus through the use of gateways.
