Certain state transitions will cause a collection event to be signaled. If the event is
enabled, this event will be sent to the Host along with the appropriate reports if
appropriate. This table lists the state transitions and notes when events will be sent to the
Host.
# From Trigger To Description
1 Unknown Power-Up Conditional This transition is made
to either the Off-Line or
On-Line state,
depending on the EC
INITCONTROLSTATE
(VID 1002005).
2 Unknown Power-Up Conditional This conditional
transition is governed by
the value of the
OFFLINESUBSTATE
EC (VID 1002010).
3 Equipment
Off-Line
Operator requests to
go On-Line
Attempt On-
Line
The SIPLACE will
immediately send an
S1F1 to request to go
On-Line.
4 Attempt On-
Line
Unsuccessful On-
Line request
Conditional This transition occurred
because the Host did
not reply to an S1F1
with an S1F2 or
because the S1F1 was
not successfully sent.

The variable CONTROLSTATE represents the current control state, and will be one of the
following values:
2II/LQH(48,30(172))/,1(
The Operator has put the SIPLACE Off-Line. In this state, the Host may not put the
Equipment On-Line, only the operator can attempt this from this state. Any Host-initiated
primary message (except S1F13 and S1F17) will be replied to with an SQF0 ABORT
message by the Equipment. 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.

2II/LQH+2672))/,1(
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.
2II/LQH$77(03721/,1(
The Operator has requested that the Equipment go On-Line, causing the transition to this
state. SIPLACE sends a single S1F1, indicating its desire to go On-Line. When either a
transmission failure (here, T3 or RTY errors) occurs, or a successful reply to the S1F1
has been received, a transmission is made out of this state.
2Q/LQH/2&$/
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.
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.
2Q/LQH5(027(
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
5HPRWH
5HODWHG9DULDEOHV
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 --
Variables".
