• 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 DeviceNet) containing the message data. The maximum
array size is dependent on the controller and must be an even
integer.
• Message Data Swap Bytes. For DeviceNet, each message data
tag can be set to swap (or not swap) the order of bytes within a
16 bit word. Select the check box to enable swapping. Clear the
check box to disable swapping. You need to check the box
when using a SLC controller or PLC processor.
• 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 DeviceNet) containing the variable data. The maximum array
size is dependent on the controller and must be an even integer.
• Variable Data Swap Bytes. For DeviceNet, each variable data tag
can be set to swap (or not swap) the order of bytes within a 16
bit word. Select the check box to enable swapping. Clear the
check box to disable swapping. You need to check the box
when using a SLC controller or PLC processor.
The address tags must be an Output data type, in the following
syntax: O:[element number]. Both the Message Trigger and Message
Data addresses must fall entirely within the scanners output size or a
maximum of 64 words, including the Message Data array size. For
example, a Message Trigger address of O:10 and a Message Data
address of O:32, with a scanner output size of 31 is not valid.
IMPORTANT
Variable Trigger and Variable Data addresses work
the same as Variable Data Swap Bytes.
