SIPLACE GEM SW Version GEM 505.01 HOST Interface Manual

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 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.

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.

On-Line/LOCAL

The local operator has control of the SIPLACE.

The only possibility of controling processing is sending RemoteStop 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 S2F41 which do not directly affect processing. For

example, the Host can enable/disable Alarms and set the Clock.

On-Line/REMOTE

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

Command).

Power

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:

1 = Equipment Off-Line

2 = Host Off-Line

3 = Attempt On-Line

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

ONLINESUBSTATE (VID 1002009) determines whether the default state is:

4 = Local

5 = Remote

3.2.4 Related Variables

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).
