CI-ControlWave EFM Appendix F / F- 23
There are five fields that allow the user to make changes:
Contract Hour – Users enter the Contract Hour for the start of the Contract Day here.
Current Heating Value (Units) – The user may select the Heating Value units from a
drop down menu; default units are BTU/Ft
3 .
Flow Rate (Units) – The user may select the Flow Rate units from a drop down menu;
default units are Ft
3 /Hour.
Energy Rate (x1000000) – The user may select the Energy Rate - Energy Units from a
drop down menu; default units are BTU. The user may select the Energy Rate - Rate Units
from a drop down menu; default units are HOUR.
Reset Meter Run’s Measurement Type - This button (bottom of menu) allows the user
to reset the meter run’s measurement type (if a mistake has occurred during configuration).
F.6.2 Meter Run I/O Configuration
Retrieving Configuration Please Wait will initially be posted on the WebBSI Web Page
when I/O Configuration has been selected followed by the Meter Run I/O Configuration
Web Page (see Figure F-15).
The Meter Run I/O Configuration Web Page provides the mechanism for assigning the
source for the inputs to the meter run calculations. From this page, the user would assign
specific transmitters and meters to a meter run. The user may select from analog
transmitters connected to I/O points, or from Smart Transmitters using BSAP or MODBUS
connected via an RS-485 serial port. In addition, the user would select the source of the
heating value, whether it is from a chromatograph and analog inputs or manually entered.
F.6.2.1 Differential Pressure, Static Pressure and Temperature Inputs
To select the source for pressure, differential pressure, and temperature, the user selects
‘Source,’ ‘Point ID’ and either the ‘BSAP Address,’ or ‘MODBUS Address.’
Analog Input is used when a transmitter is connected to the ControlWave GFC via a 4-
20mA or 1-5Vdc signal. The user must then select the Point ID on the I/O board to which
the transmitter is physically connected. In addition, the zero and span settings and the
engineering units must be assigned by clicking the ‘Zeros & Spans’ link.
Wet End is used when the internal transmitter is used. No other configuration is required.
‘BSAP’ is selected when an external Bristol Babcock Smart Transmitter (either the
TeleTrans or the MVT) is used via RS-485 communications. The only configuration required
is to assign the BSAP address (1-127) of the BBI Smart Transmitter connected to the RS-
485 port.
‘MODBUS’ is selected when an external Smart Transmitter is used via RS-485
communications. The MODBUS interface supports the register list of the Rosemount 3095
smart multivariable transmitter. No additional configuration is required. Note: This func-
tionality is only available when the Expansion Communications Module is used.
