3-40 Operating Characteristics
The message text will be displayed on the Equipment's CRT. Collection Event
S10Ack (CEID 21) occurs once the operator has acknowledged the message and an
Event Report will be sent to the Host (if enabled).
The S10F3 and S10F9 are restricted to a single TEXT data item, but S10F5 can
contain multiple TEXT data items. Each TEXT data item is limited to 160
characters.
If the Operator has not acknowledged an existing message when the Host sends
another message, the new message will be displayed and the old one discarded.
The Host can send a message with a 0-length text to clear the Operator text display.
Also, the Equipment allows the operator to send a single block message to the Host
via S10F1. The maximum length of this text is 160 characters. The S10F2 response
from the Host is ignored.
See [RefGWGEMUser] p 143 ‘Equipment Terminal Services’.
FmNT provides functionality to create data (typed in by the Operator) and send it to
the Host using GemTerminalReq. Operator can enter his message through the GEM
property page dialog (terminal page), or via SECS/GEM page of Run Window. The
message will be sent when the operator presses the Send button on screen.
FmNT provides a Terminal Display to display text received from the Host. FmNT
will implement a finite state machine for this functionality, as described in
[RefGWGEMUser] p 145 ‘Equipment Terminal - Finite State Machine’.
FmNT notifies the operator that a text message has arrived from the Host by blinking
the GEM status bar at lower portion of screen. If the beep option has been selected a
beep once every half a second will be used to catch operator’s attention. The
operator can then view the incoming message through GEM property page dialog
(terminal page). He can also view the message from the SECS/GEM page of Run
Window. In the same locations, there are provisions for the operator to send a
message to host.
