Publication 1753-UM002A-EN-P - July 2005
5-10 Configure DeviceNet Nodes and Connections
Should the scanner detect a mismatch with any of the key parameters
checked, an Electronic Key failure (status code 73) will occur for that
slave device and the scanner will abort the connection establishment
process.
Configure Standard Inputs
The Input tab lets you define how standard data from all of the
scanner’s slave devices are mapped into the input image of the
controller.
The graphical window at the top shows each device’s node number,
catalog number, type of connection that is used between the scanner
and the slave device (strobed, polled, cyclic or change of state), the
amount of data that will be exchanged (in bytes), and the location of
the data within the controller’s scanner’s standard input image.
