EIA-485 (RS-485) Serial
Communications
COM1
EIA-232 (RS-232) Serial
Communications
COM2
Issued Feb-07
The LOI supports ROC or Modbus slave protocol communications. The
LOI also supports the log-on security feature of the FB107, if you
enable the security on LOI using ROCLINK 800.
Default values for the LOI port are: 19,200 baud rate, 8 data bits, 1 stop
bit, no parity, group 1, and address 2.
COM1 provides EIA-485 (RS-485) serial communication protocols
with baud rates from 300 to 115.2 K
differential data transmissions over distances of up to 1220 meter
(4000 feet).
The EIA-485 (RS-485) drivers are designed for true multi-point
applications with multiple devices on a single bus.
Note: COM1 is labeled 485 on the CPU.
Use COM1 to monitor or modify the FB107 from a remote site, using a
host or ROCLINK 800. COM1 also supports the log-on security feature
of the FB107 if you enable the security on COM1 using ROCLINK 800.
COM1 sends and receives messages using the ROC or Modbus slave
and host protocol. COM1 is capable of initiating a message in support of
Spontaneous-Report-by-Exception (SRBX) alarming.
Default values for the EIA-485 (RS-485) communications are: 19,200
baud rate, 8 data bits, 1 stop bit, no parity, 10 millisecond key-on delay,
and 10 millisecond key-off delay. The maximum baud rate is 115.2
Kbps.
COM2 allows for EIA-232 (RS-232) asynchronous serial
communication protocols with baud rates from 300 to 115.2 K, host
serial interface COM2 provides standard single-ended data
.
transmission over distances of up to 15 meter (50 feet).
Use COM2 to monitor or alter the FB107 from a remote site, using
ROCLINK 800. COM2 also supports the log-on security feature of the
FB107 if the security on COM2 is enabled in ROCLINK 800.
COM2 sends and receives messages using the ROC or Modbus slave or
host protocol. COM2 is capable of initiating a message in support of
Spontaneous-Report-by-Exception (SRBX) alarming.
Default values for the EIA-232 (RS-232) communications module are:
19,200 baud rate, 8 data bits, 1 stop bit, no parity, 10 millisecond key-on
delay, and 10 millisecond key-off delay. The maximum baud rate is
115.2 Kbps.
When you install a communications module in slot 2, the
Note:
firmware redirects communications port (COM2) on the CPU to
the type of module installed in slot 2. Configure COM2 based on
the type of communication module installed in slot 2.
