Software Description Tank Gate Interface Parameter Class Description Command Output command data Constant Weights & Measures parameter Scratch Temporary data that is typically hidden from the user System System data (should not be changed by the user) The user-related parameters are the Config, Command and Dynamic parameters. These parameters are available in the Edit Point window of ViewRTU. The remaining parameters are internal to the Software Block.
8315 TGI Software Description PntCheckSum Parameter The PntCheckSum is a CRC-16 checksum of the Configuration Parameters of a point. Most points have the PntCheckSum parameter; a few like the CLK (Clock) Point, DIAG (Diagnostics) Point, and the register points (BREG, IREG, and DREG) do not. Any time a Configuration Parameter is changed, the Tank Gate Interface re-calculates the checksum. The PntCheckSum is used at initialization to validate each point in the database.
Software Description Tank Gate Interface When FuelsManager is the Host system, the Change of State method has the advantage of being very efficient. Only the data that has changed is reported. Change of State is not available when using Modbus. 4.3.3 Change of State-Related Parameters In order to support the Change of State method, many points have additional configuration parameters included.
8315 TGI Software Description The Modbus Slave protocol handler is flexible, allowing the user to set options for handling several aspects of Modbus communications. The Modbus Slave uses the GWBLK Gateway Block as a lookup table for data addresses. The Gateway Block allows the user to specify data address and point reference combinations. This allows the Tank Gate Interface to be used with an existing system that is already configured.
Software Description Tank Gate Interface 4.3.5 Fixed Modbus Map For each version of the Tank Gate Interface, there is a fixed map of data registers.
