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

INITCOMMSTATE 1002002
ESTABLISHCOMMUNICATIONSTIMER 1002003
HEARTBEAT 1002055

The SIPLACE supports the following Establish Communications message formats for
older Host implementations. If the Host intends to use the Control State Off-Line feature,
CONFIGCONNECT should always be set to S1F13/14.
S1F1/S1F2
S1F65/S1F66

This section describes the Control characteristics of the Equipment. The Equipment may
be in one of the following control states. This value is reflected in status variable
CONTROLSTATE (VID 1002006).
Value State
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

The Control State of the Equipment is illustrated in the Control Finite State Diagram. The
SIPLACE behaves differently and will accept different messages depending on its current
control state. The purpose of this diagram is to make clear to the Host exactly what is
happening at the Equipment. The logic for these states and transitions is the logic
specified in the GEM standard.

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

Conditional This transition occurred
because the Host did
not reply to an S1F1
with an S1F2 or
because the S1F1 was
not successfully sent.
