    • GIS GIC to LIC Communications

    This section is based on TN-0157 GIS Programming. This Tech Note contain configuration details and programming styles that were not an absolute requirement or specification. It was to layout guidelines for GIS programming to promote consistency.

    The reason this is a Tech Note rather than a Spec was that specifications were also contract requirements. Changing contractual requirements after the contract was signed was an onerous process so using a technical note to detail configuration information was the route chosen.

    GIC to LIC communications

    Communications between the GIC and the LIC consist of tag of the user-defined type UDT_SafetyArray. This is essentially an array of 128 bits plus CONNECTION_STATUS.
