Set up Modbus TCP parameters
If the meter firmware supports Modbus TCP slave functionality, the following controls will
be available.
• Modbus TCP unit identifier: Enter the Modbus TCP unit identifier here. Valid values are
0-255.
• Enable alternate Modbus TCP port: The standard TCP port for Modbus TCP is port 502.
This port is always enabled in a meter that supports Modbus TCP. By selecting this
option, you can also enable Modbus TCP communications on a secondary TCP port
specified by Alternate Modbus TCP port.
• Alternate Modbus TCP port: Enter the alternate TCP port number here after selecting
Enable alternate modbus TCP port. Valid port numbers are from 1 to 65535. The
meter will not allow some port numbers that are either used by the meter or are
defined port numbers for other protocols. Daniel MeterLink
™
will prompt you if it
was not able to write the specified port number to the meter.
2.7 Set up HART
®
communications
Daniel Ultrasonic Flow Meters are HART-capable devices utilizing the 4-20mA signal
Analog Output 1 on the CPU Module, in which the digital signal is sent from the field
device (Daniel Ultrasonic Flow Meter) to the host (PC running AMS
™
Device Manager or a
Field Communicator). An external 24V power supply is required for the analog signal from
the CPU Module.
The HART Device Description application provides dynamic variables, device-specific
commands, universal commands and common practice commands in accordance with the
HART Communication Foundation. The Device Description defines the communication
details from the device to the host (e.g. menus for the Field Communicator, graphical
displays for
AMS Device Manager and the device parameters - process variables, pressure,
temperature, diagnostics and three status alert groups - Failed, Maintenance and
Advisory). Refer to the HART Field Device Specification (P/N 3-9000-762) for details.
