Communications between the Telescope LIC and the GIC consist three tags, an array of 128 BOOLs, two REALs, Azimuth and Altitude positions.
Telescope to GIC bit assignments
Communications between the Telescope LIC and the GIC are via a single tag, named MLIC_to_GIC. MLIC_to_GIC is a user-defined type SAFETY_ARRAY which consists of the the safety connection status and an array of 128 BOOL. Assignments are listed below:
