7.2.7 Configuration of W+M systems
Description of the sealing process
Locking mechanisms in Tankvision:
Connected PCs are registered in the system by assigning the MAC address. Once the system has
been locked, only these PCs are accepted and can display calibrated data.
When the W+M switch is flipped, a checksum is calculated and set.
This calculation is repeated every 8 hours. If this checksum deviates from that at the time of sealing,
changes have been made to the system. It is no longer possible to modify W+M parameters, such
as tank tables, units and print templates, once the W+M switch has been flipped.
Recommended procedure:
It is recommended to start calibrating the tank gauging system from the field devices via possible
protocol converters and finish the process with the Tankvision inventory management system.
When calibrating the Tankvision Tank Scanner or Data Concentrator, it is recommended to start
with the unit used as the Global Configuration Store since the engineering units are configured
centrally here. These units would then not have to be checked separately in the boxes assigned (see
Section "Units").
