3.5 Wiring and I/O
Daniel MeterLink uses the TCP/IP protocol to communicate with the 960-24™ MSTS electronics
instead of Modbus ASCII or RTU. The TCP/IP protocol only works across either Ethernet, RS-485
full duplex (i.e., 4-wire), or RS-232. Daniel MeterLink
TM
can communicate with multiple meters if
they are multi-dropped using 4-wire full duplex RS-485 mode. The meter electronics is HART
capable and provides communication flexibility with Daniel 3814 Liquid Ultrasonic Flow Meters.
The HART® output provides communication with other field devices (e.g., Field Communicator
and AMS™ Device Manager software) and ultimately, communicates key diagnostic information
through PlantWeb® architecture.
The Daniel 3810 Series Ultrasonic Flow Meter electronics auto-detects the protocol used and
automatically switches between TCP/IP, Modbus ASCII, and Modbus RTU so it is not necessary to
make any meter configuration changes to change the protocol.
If not using Ethernet, a full duplex serial connection is necessary for Daniel MeterLink to
communicate with a Daniel 3814 Liquid Ultrasonic Meter.
