GENERAL
With the Fieldbus Communication Function, a field
control station (FCS) can be connected via the ACF11
or ALF111 Fieldbus Communication Module installed
in an I/O module nest to fieldbus-ready sensors and
valves. The GS covers the following communication

FUNCTION SPECIFICATIONS
Fieldbus Feature
A fieldbus is a digital, bidirectional and multi-drop connection
communication bus that connects field devices
to control systems, and which replaces conventional
4-20 mA communication. Its specifications have been
standardized by the Fieldbus Foundation. With the
multi-sensing function, various data as well as field
devices’ PVs and MVs are transferrable. A fieldbus
ensures interoperability between diverse vendors’
