  • Page 36 8315 L&J Tankway Software Description TankGate Interface 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 TankGate re-calculates the checksum.

  • Page 37: Gathering Point Data

    8300 Gathering Point Data For Host to TankGate communications, there are two primary methods for gathering point data. These methods are listed below: 4.4.1 Standard Request-Response Format The Host issues scan requests, and the TankGate responds with the data. The Scan method has the advantage of being deterministic, the response time to a particular request will always be the same.
