4-6 Application Guide
• 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 must be a SINT data type, however they can be
named anything provided it is in the following syntax: Name[element
number]. 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 any name, but you cannot use more
than one data file. For example, a Message Trigger address of
Mess_data[0] and a Message Data address of Message[1] is not valid. At
the same time, a Message Trigger address of Mess_data[0] and a
Message Data address of Mess_data[120], with a Message Data array
size of 16, is not valid because the array falls outside of the 128 byte
block.
DeviceNet Communication
and Tag Setup Screens The InView display can communicate as a slave device to a PLC-5
controller, SLC controller, ControlLogix controller, MicroLogix
controller, or CompactLogix controller with a DeviceNet module.
IMPORTANT
Variable Trigger and Variable Data addresses work
the same as Variable Array Size.
