The FB107 has the ability to limit the AGA calculation-related events to
only critical events. Selecting Enabled in the Limit Meter Events field
on the Meter Setup's Advanced tab (Meter > Setup) keeps the system
from filling the event log with unnecessary events. The events not
logged include temperature, pressure, Reynolds number, and warnings
for orifice diameter, pipe diameter, and beta ratio.
The FB107 permits device-based security. You can define and store a
maximum of 16 log-on identifiers (IDs). In order for the unit to
communicate, the log-on ID supplied to ROCLINK 800 software must
match one of the IDs stored in the FB107. This security feature is
enabled by default on the Local Operator Interface port (Security on
LOI). You can configure security protection on COM1, COM2, and
COM3, but this security is disabled by default.
The I/O database contains the I/O points the operating system firmware
supports, including the system analog inputs and variables, Multi-
Variable Sensor (MVS) values, communications, and smart application
modules. The firmware automatically determines the point type and
point number location of each installed module. It then assigns each
input and output to a point in the database and includes user-defined
configuration parameters for assigning values, statuses, or identifiers.
The firmware scans each input, placing the values into the respective
database point. These values are available for display and historical
archiving.
The FB107 supports FST user programmability. You can develop four
FST programs with a maximum length of 3000 bytes each. You
configure the number of FST lines per execution cycle in ROCLINK
800.
The FST code resides in static RAM and is backed up to flash memory
when you issue the Save Configuration function through ROCLINK
800.
Note: You must first enable FSTs (Configure > Control > FST
Registers) in order to make them available.
The PID Control applications firmware provides Proportional, Integral,
and Derivative (PID) closed-loop control for a FB107, which enables
the stable operation of a feedback control loop that employs a regulating
