The FB107 supports a Multi-Variable Sensor (MVS) module,
which plugs into any module slot (1 through 7) in the base unit or
the expansion rack. It also supports a Dual Variable Sensor (DVS)
and a Pressure module (PIM), either of which attaches to the FB107
enclosure and connects to the DVS port on the FB107 base unit.
6.1 Multi-Variable Sensor (MVS) Module Overview
The MVS module provides communications and power to remote
MVS transmitters and, in turn, provides differential pressure, static
pressure, and temperature inputs to the FB107 for orifice flow
calculations.
The module consists of interface electronics that provide the
communications link between the FB107 and up to six MVS
transmitters. The interface electronics controls communications
with the sensor module, provides scaling of process variables, aids
calibration, stores operating parameters, performs protocol
conversion, and responds to requests from the FB107.
The module provides the communications interface and the short-
circuit current-limited power required to connect up to six MVS
transmitters. You can install the MVS module in any slot on the
FB107 and expansion rack except for slot 0, where the CPU
module resides.
You can connect up to six MVS transmitters to the FB107’s
communications bus in a multi-drop connection scheme. You
must set the address of
each transmitter before you finalize the
wiring of multiple transmitters. For proper operation of multiple
MVS devices, each transmitter must have a unique address (in the
range 1 through 255).
None of the addresses can be 0 or 240.
