• 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 80 characters for
DHP) 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 80 characters for
DHP) 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 must fall entirely
within a single 80 byte block, including the Message Data array size.
You can choose to use either an Integer or ASCII data file, 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 N7:35, with a Message Data array size of 16, is not valid because
the array falls outside of the 40 word (80 byte) block.
IMPORTANT
Variable Trigger and Variable Data addresses work
the same as Variable Array Size.
