While in this state, the SIPLACE will accept either the S1F17 (Go Online), or the S1F13
(Connect Request) message. When in this state, the operator has allowed the Host to put
the Equipment On-Line, but the Host has not yet done so, or the Host has just put the
Equipment Off-Line by sending S1F15. The Host may request for the Equipment to come
On-Line by sending the S1F17 Go Online message. The Operator can not put the
Equipment On-Line from this state.
The S1F13/S1F14 messages are used to maintain the Communications Finite State
Machine. All messages (except S1F13 and S1F17) received will be replied to with the
SQF0 ABORT message. The Equipment will not send any primary messages except for
S1F13 when necessary to establish communications, and the S9F1 and S9F9 messages
for SECS errors.

The Operator has requested that the Equipment go On-Line, causing the transition to this
state. SIPLACE sends a single S1F1, indicating its desire to go On-Line. When either a
transmission failure (here, T3 or RTY errors) occurs, or a successful reply to the S1F1
has been received, a transmission is made out of this state.

The local operator has control of the SIPLACE. The Host can send S2F41 (Remote
Command), but the Equipment will reject it with 0x40 return code. However remote
commands 'STOP' and 'ABORT' are accepted even if control state is On-Line/Local.
In LOCAL mode, the Equipment continues to send Event and Alarm reports to the Host.
The Host can monitor operations, but cannot control processing. However, the Host can
still exert "controls" other than S2F41 which do not directly affect processing. For
example, the Host can enable/disable Alarms and set the Clock.

The remote Host Computer has control of the SIPLACE using S2F41 (Remote
Command).

At Power Up, the Equipment Constant INITCONTROLSTATE (VID 1002005) controls
whether ControlState is initialized to ONLINE or OFFLINE. Within the Off-Line super-
state, the Equipment Constant OFFLINESUBSTATE (VID 1002010) controls whether the
Control State defaults to:
(TXLSPHQW2II/LQH
+RVW2II/LQH
$WWHPSW On-Line
If INITCONTROLSTATE (VID 1002005) initializes to On-Line, the variable
ONLINESUBSTATE (VID 1002009) determines whether the default state is:
/RFDO

The following table lists the variables (SV's, EC's, or DVVALS) which are relevant to the
Control State. For a more complete description of these variables, see "Appendix A --
