3-34 Equipment-to-Host Messages
3.9 Equipment Terminal Services
The Equipment supports exchange of free text messages with the Host (SECS Stream 10). This
Equipment accepts the following messages from the Host, and responds accordingly if the W-Bit is
set to 1:
S10F3 /* Single Line Data */
S10F5 /* Multi-Line Data */
S10F9 /* Broadcast */
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.
FmNT provides this functionality by allowing an operator to enter his message through the SECS/GEM
Setup dialog box (Terminal tab), or via the SECS/GEM tab in the Run Window. The message will be sent
when the Operator presses the Send button on screen.
FmNT also provides a Terminal Display to display text received from the Host from the SECS/GEM
Setup dialog box (Terminal tab) or via the SECS/GEM tab in the Run Window.
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 the
SECS/GEM Setup dialog box (Terminal tab), or via the SECS/GEM tab in the Run Window. In the same
locations, there are provisions for the Operator to send a message to the Host.
