General Information
1-19
1.4.8
Spontaneous-Report-By-Exception (SRBX) Alarming
The SRBX functionality allows you to set up a communications port that
enables the FB107 to contact the host computer when specified alarm
conditions exist. To configure SRBX alarming, each communications
port must have the SRBX parameter enabled, each point must have the
alarming parameter enabled, and points must have an SRBX parameter
(SRBX on Set, SRBX on Clear, or SRBX on Set & Clear) selected.
SRBX occurs over a serial line if the host is set up for receiving field-
initiated calls.
1.4.9
Softpoints
Softpoints
are global data storage areas that any FB107 application can
use. For example, a softpoint may store the results of a specified FST
calculation or store an intermediate result of a specified value an FST or
user program acquires. Softpoints consist of a tag identifier, one integer
value, and twenty floating values. Thirty-two softpoints provide storage
for over 704 variables.
1.4.10 Opcodes
Use the
Opcode Table
to group data being polled for more efficient
communications. You can assign parameters from different point types
can be assigned to the opcode table data points, which can substantially
reduce the number of polls from a host computer. The FB107 supports
eight opcode tables, each with 44 values.
1.4.11 Pass Through Communications
By using the FB107 communications ports, Pass Through
Communications mode allows one unit to receive data and then pass it
through to other devices connected on any other communications port.
For example, the host communicates via a radio on the FB107 COM2
port. Other FB107 units can then be connected via EIA-485 (RS-485) on
the COM1 port of the first FB107, and then all the FB107 units can use
the one radio to communicate to the host.
Note:
The Device Group of the FB107 receiving the data must match the
Device Group of the FB107s to which the data is passed. The
Device Group is located on the Information screen (
ROC
>
Information
).
1.4.12 ROC and Modbus Protocols
The FB107 has the capability to communicate with other devices using
ROC or Modbus protocols. The firmware can automatically detect the
two protocols (ROC or Modbus) at baud rates of up to 115.2 Kbps bps.
