*  Names are user settable (to a maximum of 32 characters), and only on outputs when they are controlled remotely (i.e., 

MUXed). 

 

These are the typical objects that may be commanded on the fly by a user or from GCL++, and also include the Outputs 

(AV1-3) when they are MUXed. Never command the Configuration Variables (AV12, AV21-13) on the fly.  

System Events and Statistics 

System Stats (AV34) 

The Description field in this object provides a count of notable events that have occurred. Each 
statistic consists of an event code (H- Hardware, C- Communication, S-S two-digit code) and 
an event count. With the exception of the reset count (H04) and the flash programming count (H05), 
event counts are reset on power up. The PresentValue indicates how many different types of events 
have occurred since power up.
