Manually Configure the DeviceNet Network Chapter 5
Scanlist
These devices have been assigned to be slave I/O to this scanner. A slave
device on the DeviceNet network can be owned by only one master at a time.
Devices in the scanlist are configured using the input and output tabs.
Automap on Add
Automap allows a slave’s I/O to be automatically mapped into the scanner’s
input or output image tables when the slave device is added to the scanlist. do
not check this box if you intend to map a slave device into a particular input or
output memory location.
If you do select Automap, you will be prompted to choose how the data
should be aligned in the scanner.
Edit I/O Parameters
These parameters will vary depending upon the slave device. Information on
configurable parameters is usually provided in the device’s documentation.
Electronic Key
The electronic key is used to make sure that a particular slave device always
matches the intended device when the scanner module initiates a connection
to it. When one of the devices in the Scanlist section is highlighted, these boxes
may be checked to indicate to what extent the key parameters must match the
actual device on the network. A match of just Device Type can be selected or
the additional parameters of Vendor ID, Product Code, Major Revision, and
Minor Revision may be incrementally added.
For Major and Minor Revisions, you can select or higher to indicate that either
an exact match, or some higher revision value of the revision is required.
If the scanner module detects a mismatch with any of the key parameters
checked, an AutoVerify failure will occur for that slave device and the scanner
module will not continue the connection allocation process.
