4. Message Summary
4.1 Host to Equipment
This section describes primary SECS messages sent by the Host, and the associated reply messages from the Equipment.
The column headed "CState" in the table below indicates the control state the Equipment must be in to accept the message.
The current value of the Equipment Control State can be found in variable CONTROLSTATE (VID 263). Possible values
for this column are as follows:
Table 6 Control State Values.
Value Cstate
1 Off-Line/Equipment Off-Line
2 Off-Line/Attempt On-Line
3 Off-Line/Host Off-Line
4 On-Line/Local
5 On-Line/Remote
Unlawful messages sent to the Equipment while Control State is Off-Line (1, 2, or 3) will be replied to with a SnF0
message. Thus, the Host will only ever see values of 4 or 5 for CONTROLSTATE.
In the column headed "Notes", those messages marked with "E" are extensions beyond GEM. Those messages marked
with "N" are provided for non-GEM or older GEM compatibility.
