Configure Gas Chromatograph Parameters - Emerson Daniel 3410 Series Operation Manual

Configurations
January 2019
• Fixed temperature - If Fixed was selected on the Daniel MeterLink Startup Page for
Temperature It will also be enabled if a live temperature input was selected. Enter a
fixed value to use for calculations if the live input goes into alarm. Enter an average
temperature of the process fluid.
• Temperature alarm - Enter the low and high alarm limits. A temperature reading
outside of these limits causes a Temperature Validity alarm. The Alarm selection
determines what value to use while a live input is in alarm. This value is common with
the pressure Alarm selection so when one is changed, the other will change to match.
5.7.3 Configure the pressure parameters for the meter
Pressure reading - Select either Gage or Absolute for the type of pressure reading
•
desired. If a live pressure transmitter is connected, select the type of reading the
transmitter outputs. If Absolute is selected, you must also enter the Atmospheric
pressure.
• Live pressure - Enter in the scaling for the transmitter connected to the analog input.
Min. input is the zero scale pressure of the transmitter (i.e. 1 Volt or 4mA). Max. input is
the full scale pressure of the transmitter (i.e. 5 Volts or 20 mA).
• Fixed pressure - Enabled if Fixed was selected for Temperature for meter corrections on
the Startup Page. It will also be enabled if a live temperature input was selected to
allow you to enter a fixed value to use for calculations if the live input goes into alarm.
Enter an average pressure of the process fluid.
• Pressure alarm - Enter the low and high alarm limits. A pressure reading outside of
these limits causes a Pressure Validity alarm. The Alarm selection determines what
value to use while a live input is in alarm. This value is common with the temperature
Alarm selection so when one is changed, the other will change to match.

Configure Gas Chromatograph parameters

Use the Meter > Field Setup Wizard menu and enable the View Gas Chromatograph
setup checkbox. Configure the following parameters to setup a serial port as a Modbus
master for polling a GC.
• Port - Select which port will be connected to the GC. While a serial port is configured for
communications to a GC, it will not act as a Modbus slave device for communications
from Daniel MeterLink or a SCADA system
• GC protocol - Select the protocol for which the GC is configured. The Daniel Gas
Ultrasonic meter uses 7 data bits, Even parity, and 1 stop bit for ASCII Modbus and 8
data bits, No parity, and 1 stop bit for RTU Modbus.
• GC baud rate - Select the baud rate for which the GC is configured.
• GC comms address/unit identifier - Enter the Modbus ID of the GC.
• GC IP address - This option will be enabled only when the Ethernet is selected.
• GC TCP/IP port number - This option will be enabled only when the Ethernet is selected.
