10–16 Terminal and Communication Setup
Publication 2706-817
Port Power-Up
This option determines how the RS-232 port is configured at
Power-Up.
•
The MessageBuilder option configures the terminal to power-up
with the communication parameters defined to communicate with
a computer where MessageBuilder software resides, for instance
to upload the Historic Event Stack
•
The Auxiliary option configures the terminal to power-up with an
ASCII Triggering device or the communication device defined in
the Aux. tab dialog.
The terminal operator can use the Front Panel Editor to toggle this
option.
Note: This option may affect downloading an application, if the
MessageView terminal is configured to the Auxiliary Device when
an attempt is made at communicating with a computer. To correct
this situation, change the port configuration of the receiving
MessageView terminal via the Front Panel Editor. See the section on
Page 5–3 that discusses switching RS-232 settings.
Handshake Timeout
Handshaking is an option used to confirm that the information has
been received by the controller, whether a logic controller or an
ASCII Triggering device. If the terminal does not receive the
handshake within a certain time, a Timeout message appears on the
display. See the discussion on handshaking on Page 4–26.
Set the Timeout time by selecting a value from the Handshake
Timeout spin control. The range is 0 to 60 seconds, default is 4
seconds.
