Tankvision Gauge Link Operation
Hauser 23
For example:
It is required that the second gauge needs to be removed from the system, type the following:
BLANK01(return)
FULLBLANK(return)
This command removes all the gauges and parameters from the Tankvision Gauge Link and
defaults the holding register database back to no gauges in the system.
This command is used if you require to start configuration from a fresh.
ENG=ENSITE(return)
This command allows Honeywell Enraf configuration PC tool, Ensite, to be connected to
Tankvision Gauge Link engineering port and support all the features that the Ensite
software require.
Once the above command has been set, a 4 minute timer is set to allow time for the engineer
to disconnect the terminal emulation software and connect the Ensite software. If no data
has been seen after four minutes on the RS232 port of the Tankvision Gauge Link, the port
will then switch back to its normal mode of operation and allow the terminal emulation
software to be used. Once data has been seen on the RS232 port, the timer will reset and if
no data is then seen for 2 minutes the Tankvision Gauge Link will default back to the
terminal emulation mode.
If the Tankvision Gauge Link is powered down and back up when in Ensite mode, it will
power back up in normal, terminal emulation mode, and will need to be set back to Ensite
mode by using the above command.
If Ensite is not polling for data when in this mode, the Tankvision Gauge Link will then
starting poll for normal data as configured in its database, this allows the Tankvision Gauge
Link to keep the data in its database as live as possible, if Ensite then starts polling for data,
the Tankvision Gauge Link will then switch to tunnelling mode and pass the data through
from Ensite to the gauges on the BPM fieldbus.
The CIU address of the Tankvision Gauge Link is always set to 0 (zero). The baud rate of the
Ensite port can run at either 1200 or 2400, this baud rate is determined by what the Field
bus baud rate is set to using the FTS command. Both the Field bus and Ensite baud rates need
to be the same.
The COMMUNICATIONS LED of the fieldbus module will not light up when Ensite is
tunnelling data, but it will light if the Tankvision Gauge Link polls for valid data. This can be
useful to determine what is driving the BPM field bus, Ensite or the Tankvision Gauge Link.
ENG=ENGAUGE(return)
This command offers all the features that the Ensite mode offers, including the Honeywell
Enraf Flexconn configuration tool.
Disabling, CIU address etc are the same as the Ensite mode.
For optimum ENgauge operation with the TVGL, set ENgauge as follows:
• New site
• Enter the units of the parameters
• Add a device to the comms
• Add a field connector
– Choose smartlink and give it a name
• Select the SmartLink and change its comms parameters
– GPU: 1200, 7, O, 1
– Flexconn: 1200, 8, N, 1
• Add a Tank
