Analog Output
The Analog output on the IOEXP board is used by the Primary run for either flow
recording or PID use; the default is flow recording, in which case the Analog output
is proportional to the flow rate in percent of the configured Max Flow Rate for the
Primary run (Run1 is the default primary run). This output is driven by the PID
controller of the primary run if the run’s PID has been set for Analog mode.
Pulse Input
Two inputs are available (one on the main board, one on the IOEXP board) that
accept pulses at rates up to 5,000 Hz. Counts are read using a HSCOUNT module
which reports a raw pulse total and frequency value. These counters can be
configured as either plain pulse counters or Turbine meter counters.
For plain pulse counting a configurable scaling factor can be used to convert pulses
into other units i.e., if each pulse is the equivalent of 5 gallons, a scaling factor of 5
converts the total to gallon units. The frequency and total can be read in 'raw' units
(counts and Hertz) and also in scaled units. Default pulse scaling factor is 1.0.
For Turbine meter usage an additional meter factor (in units of pulses-per-ACF)
and maximum turbine frequency must be configured.
Communication Port Assignments
PORT #1 - Pseudo-slave local port, 19200 bps.
PORT #2 - BSAP or MODBUS network port, 9600 bps.
PORT#3 - IOEXP port to the external TIB/3508, 1200 bps.
These ports differ from typical ACCOL load port usage in that their baud rate can
be changed on-line. The Network and Expanded port RTS/CTS mode and delay
time can also be changed on-line.
Communication Port Usage
The Local port is used for local configuration and data collection. It typically
connects to a PC or Laptop that is running a user-interface software package such
as the Universal Operator Interface (UOI) or Open BSI’s Dataview.
