SIPLACE GEM SW Version GEM 505.03 SP1 HOST Interface Manual

{ XE Off-Line/HOST OFF-LINE }Off-Line/HOST OFF-LINE

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 {XE "S1F15"}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

SnF0 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.

{ XE Off-Line/ATTEMPT ON-LINE }Off-Line/ATTEMPT ON-LINE

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.

{XE "LOCAL"}On-Line/LOCAL

The local operator has control of the SIPLACE.

The only possibility of controling processing is sending RemoteStop {XE "S2F41 "}S2F41

to equipment. Other Remote Commands will be rejected with 0x40 by equipment.In

LOCAL mode, the Equipment continues to send Event and Alarm reports to the Host.

The Host can monitor operations, but cannot control processing, despite RemoteStop.

However, the Host can still exert "controls" other than {XE "S2F41 "}S2F41 which do not

directly affect processing. For example, the Host can enable/disable Alarms and set the

Clock.

{XE "REMOTE "}On-Line/REMOTE

The remote Host Computer has control of the SIPLACE using {XE "S2F41 "}S2F41

(Remote Command).

Power Up{XE "Power Up"}

At Power Up, the Equipment Constant {XE "INITCONTROLSTATE

"}INITCONTROLSTATE (VID 1002005) controls whether ControlState is initialized to

{XE "ONLINE "}ONLINE or {XE "OFFLINE"}OFFLINE. Within the Off-Line super-state,

the Equipment Constant {XE "OFFLINSUBSTATE "}OFFLINESUBSTATE (VID

1002010) controls whether the Control State defaults to:

1 = Equipment Off-Line

2 = Host Off-Line

3 = Attempt On-Line

If INITCONTROLSTATE (VID 1002005) initializes to On-Line, the variable {XE

"ONLINESUBSTATE "}ONLINESUBSTATE (VID 1002009) determines whether

the default state is:

4 = Local

5 = Remote

3.3 Process States

The Process State Diagram illustrates in detail the processing at the SIPLACE.

In some state transitions there will be an intermediate state (A, B, C) for a short time (see

charpter intermediate states).
