Operation Tankvision Gauge Link
18 Hauser
The type of Field driver is also displayed which will be either GPU (Honeywell Enraf protocol)
or TRL (Emerson protocol). The Host baud rate (HTS), Field baud rate (FTS) and Host parity
(HPA) are also displayed.
The GPU gain is displayed, this gain will only take affect if the fieldbus is GPU. The
termination and bias resistors are also shown if they are enabled or not.
The above information can be displayed by typing in the INFO(return) command.
7.1.3 Typing and entering a command
Entering a configuration command into Tankvision Gauge Link is done by simply typing the
text into the terminal emulation software and pressing return at the end of the command.
E.g. to print general status and information type: "INFO(return)".
This command will print the information shown in the above section.
After most valid commands an ‘OK’ message will be printed. If an ‘INVALID COMMAND’ or
‘OUT OF RANGE’ message is printed, then re-type the command or investigate the ‘out of
range’ message.
All valid commands are saved in Tankvision Gauge Link flash memory, so when the unit is
powered down and back up the configuration will remain.
7.1.4 Commands
INFO(return)
This command prints the information shown in the above section.
FTS=XXXX(return)
Where XXXX is a 4 digit number.
This command sets the field bus baud rate. If the field driver selected was a TRL driver, then
this command will not have any effect on the Field bus baud rate, because the TRL/2 field
bus is always set to 4800 baud. If the Field driver selected is a GPU driver then there is a
choice of 2 baud rates, 1200 and 2400 baud.
When setting the BPM baud rate to 2400 the jumper link (LK_TS) on the BPM
communication needs to be fitted.
To configure the GPU field bus with a 1200 baud rate, type: FTS=1200(return)
To configure the GPU field bus with a 2400 baud rate, type: FTS=2400(return)
Any other baud rate and an ‘INVALID COMMAND’ message will be printed.
HTS=XXXX(return)
Where XXXX is a 4 digit number.
This command sets the host RS485 field bus baud rate. There are a range of different baud
rates which this command supports, see below the baud rates with the command to set the
baud rate.
Baud rate Command
1200 HTS=1200(return)
2400 HTS=2400(return)
4800 HTS=4800(return)
9600 HTS=9600(return)
