FloBoss 107 Instruction Manual
Revised June-2017 General Information 1-11
Adding an expansion rack to the FB107 base unit increases I/O by four
slots for a total of six slots of I/O. The FB107 supports up to six I/O
modules and one CPU I/O assembly.
Other available I/O modules include the 8-point AI/DI, the 6-point
AO/DO, the Discrete Output Relay (DOR) module, the HART module,
the Pulse Input (PI) module, the MVS I/O module, and the Resistance
Temperature Detector (RTD) module (see
Chapter 4, Inputs and
Outputs ). The Multi-Variable Sensor (MVS), Dual Variable Sensor
(DVS), and Pressure module (PM) are factory-installed options (see
Chapter 5, Sensors and Transducers ).
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.
Note:
See Chapter 4, Inputs and Outputs, for more information on
FB107 I/O modules.
1.3.11 Optional Communication Modules
– COM3
Optional communication modules provide 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 following types of communication modules:

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).

Enhanced Communication module (ECM) provides an Ethernet and a
USB 2.0 port.

Dial-Up Modem module provides communication over a Public-
Switched Telephone Network (PSTN) up to 2400 bps bits per second
(bps).
