I/O Scanner Parameters
• Output Size. The number of words (0 to 64) received by the
InView display from the scanner with each I/O message. The
default is 0, which means no output I/O data is exchanged with
the scanner. The output size must match the configuration in the
master device. A minimum of 19 words is needed because the
Message and Variable Data array sizes minimums are 16 bytes
each plus 1 word each for the trigger.
• Bus-off Interrupt. The action to take when a Bus-off Interrupt
occurs on the network. The options are Hold in Reset or Reset
and Continue Communications. Hold in Reset holds the InView
display and waits for DeviceNet communications to be reset.
Reset and Continue Communications resets DeviceNet
communications and attempts to re-establish the
communications link.
DeviceNet Tag Setup
• Message Trigger Address. The controller address that triggers a
message to display. This toggles between 0 and 1 in the
controller.
IMPORTANT
All four tags for Message Trigger Address, Message
Data Address, Variable Trigger Address, Variable
Data Address, and the array sizes must be entered
and established in the controller as valid tags even if
they are not used.
