FloBoss 103/104 Instruction Manual
Revised August-2017 General Information 1-15
temperature, pressure, Reynolds number, and warnings for orifice
diameter, pipe diameter, and beta ratio.
1.3.3 Security
The FB100 provides for security within the unit. A maximum of 16 log-
on identifiers (IDs) may be stored. 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 FB100. The Local Operator Interface port (Security
on LOI) has security Enabled by default. The Comm 1 and Comm 2 can
likewise be configured to have security protection, but is disabled by
default.
1.3.4 Function Sequence Tables (FST)
The FB100 supports FST user programmability. Two FST programs
can be developed with a maximum length of 3000 bytes each (typically
300 lines of code). The number of FST lines per execution cycle can be
configured in ROCLINK 800 software. The number set on the
ROC >
Information screen determines both FST programs.
The FST code resides in static RAM and is backed up to flash memory
when the Save Configuration function is issued through ROCLINK 800
software.
Note
:
For further information on FSTs, refer to the Function Sequence
Table (FST) User Manual (D301058X012).
1.3.5 PID Control
PID Control is available when the optional I/O termination points are
installed. PID (Proportional, Integral, and Derivative) functionality
calculates both the Primary Control and Override Control change in
output. PID Control then selects which Control is to be used, based
upon whether the High Override Type Select or Low Override Type
Select is chosen and adjusts the Output control as necessary. The Output
of the PID functions can be implemented through an Analog Output or
the two Discrete Outputs.
1.3.6 Spontaneous-Report-By-Exception (SRBX) Alarming
The SRBX functionality allows a communications port to be set up to
enable the FloBoss to contact the host computer when specified alarm
conditions exist. To configure SRBX alarming, each comm port must
have the SRBX parameter enabled, each point must have the alarming
parameter enabled, and points must have the SRBX Set on Clear
parameter set.
