954 SmartServo FlexLine
7.3.10.2 System Description
The FlexLine 954 servo gauges act as Rex gauges with the help of
CAN- TRL/2 card. The CAN-TRL/2 communication card for FlexLine
gauge is added to integrate to the Emerson system. The Rex Gauge
and Rosemount Tankmaster (Emerson tank inventory) communicates
over TRL/2 network and uses Modbus protocol. When Rex gauge is
replaced in field with FlexLine gauge, the Rosemount TankMaster gets
the data (for example: product level, temperature) from FlexLine gauge
same as Rex gauge.
The FlexLine gauge 954 has the capability to connect directly to
Emerson TRL/2 field bus. The Rex or TRL/2 RTG gauges can be
replaced with FlexLine gauge with great ease, minimum modifications,
and quick turnaround time and quick turnaround time.
The FlexLine gauge communicates with TRL/2 FSK protocol over
Modbus RTU and can interface with Enraf® FCU 2160/65/75 or tank
hub 2410 or FBM 2180.
The system integrates with Rosemount TankMaster Win OPI and
provides level, temperature, and other inputs to the system. Replace the
Rex gauge (with or without DAU) with FlexLine gauge and RDU with
Smartline display.
The Figure 7-27 shows the Emerson system with Rex gauges, and one
of its gauge is replaced by FlexLine 954 gauge.
