• Message Trigger Address. The controller address that triggers a
message to display. This toggles between 0 and 1 in the
controller.
• Message Data Address. The starting address of the message data
displayed. The message data contains the trigger command that
the InView display recognizes (^T[message number]^M).
• Message Array Size. The size of the array (16 to 128 characters
for ControlNet) containing the message data. The maximum
array size is dependent on the controller and must be an even
integer.
• Variable Trigger Address. The controller address that triggers a
message variable to display. This toggles between 0 and 1 in the
controller.
• Variable Data Address. The starting address of the variable data
displayed. The variable data contains the update variable
command that the InView display recognizes
(^V[variable data]\[variable number]^M).
• Variable Array Size. The size of the array (16 to 128 characters
for ControlNet) containing the variable data. The maximum
array size is dependent on the controller and must be an even
integer.
The address tags are either an Integer (N) or ASCII (A) data file. Both
the Message Trigger and Message Data addresses fall entirely within a
single 128 byte block, including the Message Data array size. You can
choose to use either an Integer or ASCII data file, but you cannot use
more than one data file. For example, a Message Trigger address of
N7:0 and a Message Data address of N9:0 is not valid. At the same
time, a Message Trigger address of N7:0 and a Message Data address
of N7:60, with a Message Data array size of 16, is not valid because
the array falls outside of the 64 word (128 byte) block.
IMPORTANT
Variable Trigger and Variable Data addresses work
the same as Variable Array Size.
