Tankvision Gauge Link Operation
Hauser 27
The below inputs to the Emerson REX gauge are mapped to the TRL/2 registers. These will
only be picked up from the gauge with the address in holding registers 0 -31. These will not
be picked up from a DAU.
For example:
A system has a REX gauge with an address of 2 and a DAU for temperature of 102. Live
water and vapour temperature is also required, these will be mapped to Analogue input
current 1 and HART input 1 respectively in the REX gauge. Configure the Tankvision Gauge
Link as follows:
7.1.9 Worked examples
Example 1
A system requires to be connected to 5 off Honeywell Enraf gauges. GPU baud rate is 1200.
The modbus interface is 9600, None, 8, 1.
• Gauge address = 1, needs level and temp. Gauge type 854.
• Gauge address = 2, needs level and temp. Gauge type 873.
• Gauge address = 5, needs level, temp, temp elements, water dip and density. Gauge type
854.
• Gauge address = 9, needs level. Temp and its elements are from an 864 with address 19.
Gauge type 873.
• Gauge address = 20, needs level and temp. Gauge type is an Enraf emulation coming from
a none Enraf gauge.
Ensure the Tankvision Gauge Link is the Enraf version.
