Address recovery will not work for DeviceNet device which has physical
switches/jumpers for setting MAC address. It works for DeviceNet devices
whose MAC address can be dynamically set from either the LD 800DN Web
interface or by any device specific configuration tools, for example,
RSNetworks for DeviceNet.
•
For any errors for DeviceNet devices that is reported in Unit Status in Control
Builder, due to communication break between the LD 800DN and the device,
the user can still force a value into the output channel of the device from
Control Builder or from the 1131 application. This output channel value shall
be written into the LD 800DN. This value shall be written into the device once
the communication between the LD 800DN and the device is restored.
Some devices like Allen Bradley PLC do not support client CI873 going offline
without closing existing connection. Since, the existing connections of such
devices with CI873 are not closed when the latter is hot removed, this could lead
to connection starvation. The error/status that is displayed in the Unit Status of
such device is,
No more consumer resources available in the
producing object
.
Therefore, communication with such devices may fail during the hot swap of the
CI873 module.
The DeviceNet EDS file could have a configuration parameters related to Safer
State Value (or a 'Fault Action' parameter) that can be configured to 'Clear data' or
'Hold last value', in case the deviceNet device looses communication with LD
800DN.
User needs to configure the configuration parameters for the channels of the
device have desired result.
