8300	8315 L&J Tankway Software Description

4.2TankGate Software Blocks

The user can configure pre-defined subprograms known as Software Blocks. These software blocks program the TankGate to perform various tasks, such as scaling an analog input value, or scanning level, temperature and status information from a tank gauge. Various software blocks are available depending on the communication module. Each Software Block contains all the logic, constants and data to perform a particular function. Every system function of the TankGate is accessible via a Software Block. The user only has to add Software Blocks using ViewRTU and then configure a few parameters in order to perform a desired function.

The purpose of this section is to explain the parameters of each software Block. This section does not explain the procedures used to configure the Software Blocks. Refer to the following ‘Using ViewRTU’ chapter for Software Block configuration procedures.
