Communications between the Telescope LIC and the GIC consist three tags, two REAL floating point values, Azimuth and Altitude positions; and an array of 128 BOOL values for various logic values (see below).
Telescope to GIC floating point values
TEL_Alitiude is a user-defined type UDT_SafetyAnalog which consists of the the safety connection status and a single REAL floating point value.
Tag Name | Data Type | Description |
TEL_Altitude | UDT_SafetyAnalog |
|
TEL_Altitude.Connection_Status | CONNECTION_STATUS |
|
TEL_Altitude.Data | REAL | Telescope Mount Altitude Position |
TEL_Azimuth is a user-defined type UDT_SafetyAnalog which consists of the the safety connection status and a single REAL floating point value.
Tag Name | Data Type | Description |
TEL_Azimuth | UDT_SafetyAnalog |
|
TEL_Azimuth.Connection_Status | CONNECTION_STATUS |
|
TEL_Azimuth.Data | REAL | Telescope Mount Azimuth Position |
Telescope to GIC bit assignments
