Re-configuration
Re-configuration of DeviceNet Devices and LD 800DN
The following are the re-configuration scenarios when the connection between
linking device and all connected DeviceNet devices times out for a while and are
then reconnected:
• Re-configuration of Connection related par
ameters (Scan list parameters) of
DeviceNet/LD 800DN
– When a connection related parameter is modif
ied for a device in the
Control Builder.
– When parameters like Inter Scan Delay, Expected Packet Rate,
F
oreground to Background Poll Ratio, ADR are changed for LD 800DN
in the Control Builder. See Updation of Scan List on DeviceNet Device
Parameter Change.
• Re-configuring DeviceNet Parameters on LD 800DN. See Re-configuring
DeviceNet Parameters on LD 800DN.
During re-configuration, the DeviceNet communication is stopped and restarted
as the LD 800DN is put to Idle mode before modifying any configuration data on
LD 800DN. During such time, the input data from the DeviceNet slave devices to
the CI873 is not affected. However, there is no output data from the linking
device to the DeviceNet slave devices.
If the connections related to some DeviceNet devices are changed (if some
existing connection as disabled and others are enabled) as part of a

re-configuration, the communication does not
start with a new connection. 
The LD 800DN needs to be reset so as to establish communication with
such
devices.
• Adding/deleting DeviceNet devices online
– When a new DeviceNet device is configured or added in Control Builder.
– When a DeviceNet device is deleted in the Control Builder.
