4-50 Application Guide
• Variable Array Size. The size of the array (16 to 128 characters
for RIO) containing the variable data. The maximum array size is
dependent on the controller and must be an even integer.
The address tags are an Integer (N) data file. Both the Message Trigger
and Message Data addresses must fall entirely within its designated
block transfer, including the Message Data array size.
Block Transfer Parameters
• Address. The starting address (in the correct controller format)
of the message data for the Block Transfer Read or Block
Transfer Write.
• Length. The number of words to transfer (1 to 62, or 64). The
InView display uses Length to identify the message blocks. You
must configure 2 block transfers (only 2). The first block, labeled
Message, contains both the Message Trigger and Data addresses.
The second block, labeled Variable, contains the Variable Trigger
and Variable Data addresses. Word 63 is reserved for the RIO
Pass-through.
