5.4 Control State
5.4.1 Host Sends On-Line Command
Assumption: Control State is "Host Off-Line". Variable GemControlState = 3.
Step SECS Message Description
1. H -> E S1F17 W Host instructs the Equipment to go „On-Line“.
2. H <- E S1F18 Equipment responds to successful On-Line
transition with ONLACK=0. Control state transits
to either Local or Remote as guided by EC
GemOnlineSubstate.
3. H <- E S6F11 W The Equipment signals CEID
GemControlState LOCAL or
GemControlState REMOTE.
4. H -> E S6F12 The Host acknowledges the event.
5.4.2 Host Sends Off-Line Command
Assumption: Control State is "On-Line".
Step SECS Message Description
1. H -> E S1F15 W Host instructs the Equipment to go „Off-Line“.
2. H <- E S1F16 Equipment Control State transitions to „Host
Off-Line“ (GemControlState = 3) and responds
to primary. OFLACK = 0.
5.4.3 Host Sends Remote Command
Assumption: Control State is On-Line and Remote.
Step SECS Message Description
1. H -> E S2F41 [W] The Host sends the command. The W-bit in
this message bay be either 0 or 1.
2. H <- E S2F42 If the W-bit was 1, the Equipment
acknowledges the command. If the Equipment
cannot perform the command, the
acknowledge code in this message is non-zero.
If the command can be completed
„immediately“, the command is performed and
the acknowledge code in this message is 0.
Otherwise, if the command takes a significant
amount of time to complete, the acknowledge
code is 4. Successful completion of a
command may trigger one or more events.

5.4.4 Equipment Rejects Host Command
Assumption: Control State is Local and On-Line
Step SECS Message Description
1. H -> E S2F41 [W] The Host sends the command. The W-bit in this
message may be either 0 or 1.
2. H <- E S2F42 If the W-bit in S2F41 is 1, the Equipment
acknowledges the command. The acknowledge
code in this message is 64 (Control State is
incorrect). If the W-bit is 0, this message is not
sent. In either case, the Equipment does not
perform the command.
5.4.5 Go Remote, Operator-Initiated
Step SECS Message Description
1. ControlState is Local. The Equipment operator
switches the Equipment to Remote Control.
2. H <- E S6F11 W The Equipment signals CEID GemControlState
REMOTE. Event Reports as appropriate.
3. H -> E S6F12 The Host acknowledges the report.
5.4.6 Go Local, Operator-Initiated
Step SECS Message Description
1. ControlState is Remote. The Equipment
operator switches the Equipment to Local
Control.
2. H <- E S6F11 W The Equipment signals CEID GemControlState
LOCAL. Event Reports as appropriate.
3. H -> E S6F12 The Host acknowledges the report.

5.4.7 Operator Command, Successful
Step SECS Message Description
1. ControlState is Local. The operator issues a
front-panel INITIATE PROCESS command. The
Equipment performs the command.
2. H <- E S6F11 W The Equipment signals CEID LotStart. Event
Reports as appropriate.
3. H -> E S6F12 The Host acknowledges the report.
