2-10 What Is the ArmorPoint DeviceNet Adapter?
Auto Catalog Replace
Auto Catalog Replace corrects errors that might occur when backplane
modules of the same type are removed and replaced in the wrong
location. If modules of the same type are removed and returned to the
wrong locations, the adapter identifies the returned modules, updates
their MAC IDs, and continues operation.
Backplane (1738-ADN12, -ADN18, -ADN18P)/Subnet (1738-ADNX) Baudrate
EDS parameter Backplane Baudrate is accessible from the primary
DeviceNet and sets a specific baudrate for all backplane I/O modules.
Set this parameter in RSNetWorx for DeviceNet to one of the
following baudrates:
• 125 Kbaud
• 250 Kbaud
• 500 Kbaud
• 1 Mbaud (available for all the ArmorPoint DeviceNet adapters
except the 1738-ADNX)
When you download this parameter, the adapter sends a command to
reset all present I/O modules on the backplane to the new baudrate.
If additional modules are connected to the adapter, you must
download the Backplane/Subnet Baudrate to make sure the new
modules use the same rate as the others.
IMPORTANT
If modules of different types are removed and
returned to the wrong locations, the adapter
identifies the returned modules and alerts you (via
RSNetWorx for DeviceNet, the Node Status Table,
and the Faulted Node Table) that the error has
occurred and must be corrected.
