Wiring and I/O
MeterLink uses the TCP/IP protocol to communicate with the 960-24
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. MeterLink 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 Rosemount 3812 Liquid Ultrasonic Flow Meters.
The HART
Field Communicator and AMS
communicates key diagnostic information through PlantWeb
NOTICE
If not using Ethernet, a full duplex serial connection is necessary for MeterLink to
communicate with a Rosemount 3812 Liquid Ultrasonic Meter.
The meter's 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.
3.5.1
CPU Module labeling and LED indicators
The meter's metrology mode and the status of the data transfer from the
Acquisition Module to the CPU Module is indicated via light-emitting diode (LED)
status indicators. The Write PROT. switch prevents overwriting the meter's
configuration.
