Local Operator Interface
(LOI) Port
The Local Operator Interface (LOI) port provides direct
communications between the FB100 and the serial port of an operator
interface device, such as personal computer using an EIA-232 (RS-232)
link.
The interface allows you to access the FB100 (using ROCLINK 800
software) for configuration and transfer of stored data. The LOI port is
capable of initiating a message in support of Spontaneous-Report-by-
Exception (SRBX) alarming.
The LOI terminal on the Termination module provides wiring access to
a built-in EIA-232 (RS-232) serial interface, which is capable of up to
19.2K bps operation. The operator interface port supports ROC or
Modbus protocol communications. The LOI also supports the log-on
security feature of the FB100, if you enable the Security on LOI through
the ROCLINK 800 software.
EIA-485 (RS-485) Serial
Communications on
COMM1
Use Comm 1 to monitor or alter the FB100-Series from a remote site,
using a host or ROCLINK 800 software. Comm 1 supports baud rates
up to 19,200 bps. Comm 1 also supports the log-on security feature of
the FloBoss unit if you have enabled the security on Comm 1 in
ROCLINK 800 software.
Comm 1 sends and receives messages using the ROC or Modbus
protocol. Comm 1 is capable of initiating a message in support of
Spontaneous-Report-by-Exception (SRBX) alarming. Comm 1 permits
EIA-485 (RS-485) serial communication protocols that meet EIA-485
(RS-485) specifications for differential, asynchronous transmission of
data over distances of up to 1220 m (4000 ft). The EIA-485 (RS-485)
drivers are designed for true multi-point applications with multiple
devices on a single bus.
The default values for the EIA-485 (RS-485) communications are:
▪
9600 Baud
▪
8 Data Bits
▪
1 Stop Bit
▪
No Parity
▪
10 millisecond Key On Delay and
▪
10 millisecond Key Off Delay
The maximum baud rate is 19,200 bps. You can disable the Comm 1
port (the default state is enabled) using the ROCLINK 800 Radio Power
Control screen (select
Configure
>
Control
>
Radio Power Control
from the ROCLINK 800 software’s menu).
Optional
Communications
Module (COMM2)
Two plug-in communication printed circuit boards and one
communication module allow you to customize the FB100 installation
for most communication requirements. The communication PCBs and
module provide an interface for the host communications Comm 2 port.
These cards permit serial communication protocols and dial-up modem
communications.
