Description of messages used in the communication between TCS and DC.

Messages from TCS to DC

MessageMeaning

AZABxxxAbsolute movement to azimuth xxx

AZR xxxRelative movement ( xxx or xxx degrees)
AZR xxx

PARKMovement to the PARK position

STOPStops dome movement if it is in motion

¿AZ?Requires present azimuth, status, EEPROM content, motor consumption.
¿ST?
¿EE?
¿CO?

AOFFAuto messages disabled

A_AZAuto azimuth, auto consumption, auto zero cross messages enabled.
A_CO
A_ZE

CPARxxxTCS sends new values for park position, zero cross position, zero margin constant, inertia constant.
CZERxxx
CZEMxxx
CINExxx

Messages from DC to TCS

FIN!xxxLast command executed, dome stopped at azimuth xxx.

¡ZE!xxxZero cross detected at azimuth xxx

¡AZ!xxxPresent azimuth, status, EEPROM contents, consumption. These messages are sent in response to ¿AZ? ¿ST? ¿EE? ¿CO? or as automatic information, if the corresponding option is enabled.
¡ST!
¡EE!
¡CO!

PAR!xxxConfirmation of new values for park position, zero position, zero margin or inertia constant, sent by TCS through commands CPARxxx, CZERxxx, CZEMxxx and CINExxx.
ZER!xxx
ZERM!xxx
INE!xxx

ERR!Error message. The type of error is codified in the <argument> field.
