Optional Communication Module - Com3; Optional Multi-Variable Sensor (Mvs) - Emerson FloBoss 107 Instruction Manual

1.3.11 Optional Communication Module – COM3

1.3.12 Optional Multi-Variable Sensor (MVS)

Issued Feb-07
I/O modules and one CPU I/O assembly, and can have up to 42 points
of I/O.
You can install I/O modules in slots 1 through 3 on the FB107 base unit
and in slots 4 through 6 on the expansion rack. If you install a
communications module in slot 1, you can install an I/O module in slot
7.
You can use current analog inputs of 4 to 20 mA when you select the
250-ohm resistor in the AI configuration using ROCLINK 800.
One optional communication module provides the ability to send and
receive data through COM3. The COM3 port is capable of initiating a
message in support of Spontaneous-Report-by-Exception (SRBX)
alarming.
You can install communication modules in slots 1 or 2 on the base unit.
Installing a communications module in slot 1 on the base unit activates
the COM3 communications port. Installing a communications module in
slot 2 redirects the CPU's communications port (COM2) to the type of
module installed in slot 2.
The FB107 accommodates one of the following communication
modules types:
EIA-485 (RS-485) serial communication protocols with baud rates
from 300 to 115.2 Kbps to provide standard differential data
transmissions over distances of up to 1220 meter (4000 feet).
EIA-232 (RS-232) serial communication protocols with baud rates
from 300 to 115.2 Kbps, host serial interface to provide standard
single-ended data transmission over distances of up to 15 meter (50
feet).
COM3 can communicate with other devices using ROC or Modbus host
and slave protocols. The firmware can automatically detect ROC or
Modbus slave protocols.
The optional Multi-Variable Sensor (MVS) module provides differential
pressure, static pressure, and temperature inputs to the FB107 for
differential pressure flow calculation.
You can install only one MVS module in the FB107. You can install the
MVS module in slots 1 through 3 on the base unit or in slots 4 through 7
on the expansion rack, regardless of the position of any other type of
module.
