InView Protocol
Introduction
The purpose of this document is to show the protocol that is required
to trigger messages and update variables on Allen-Bradley InView
display with the InView Protocol.
In general, messages are downloaded through the software and stored
within the display’s memory. Up to 4000 messages and 100 variables
can be created with the InView software.
Messages can be displayed using the Control-T function, Modbus
ASCII. One of three different methods can be used; 1) Priority
Messaging, 2) Add a Message, 3) Remove a Displayed Message.
Variables can be updated using the Control-V function or Modbus
ASCII.
Triggering Messages and
Updating Variables
The two functions that can be used to trigger messages and update
variables are the Control-T (CRTL-T) and the Control-V (CTRL-V). The
CTRL-T function allows for two different ways of displaying messages:
Priority Messaging and Add/Remove Messages. The CTRL-V function
is used to update variables on all displays or a specific display.
Priority Messaging will display the message number that was just
transmitted to the display. Using this function will have precedence
over any priority levels that are used with Add/Remove Messages.
Add/Remove Messages will allow for up to 64 concurrently running
messages to be shown on the display. Messages can be cleared one at
a time or all at once. These messages can have priority levels assigned
to them that will be used to determine how they are displayed.
The CTRL-T Function Frame
The CTRL-T function is used to trigger messages. This function
requires an ASCII decimal value to be used to trigger the desired
message number. The CTRL-T function has the ability for Priority
Messaging, Add a Message, or Remove a Message. Figure 9.1 shows
the format for the Control-T function and Table 9.1 shows the
acceptable values.
