• "Wrong MAC ID" Error status is not set in Unit Status for the LD 800DN in
Control Builder, if the user specifies a MAC ID for the LD 800DN, and this
MAC ID is already set for a physically available DeviceNet device on the
network but not available in the Control builder configuration that has been
downloaded to the LD 800DN.
• When the communication of DeviceNet devices is working properly with
LD 800DN, if the MAC ID is changed to a wrong MAC ID and configuration is
downloaded, then the Unit Status for the LD 800DN in Control Builder shows
error for Wrong MAC ID. However, the communication between LD
800DN
and DeviceNet devices continues as before the MAC ID was changed. The
communication between CI873 and LD 800DN is also not affected.
• Some devices do not accept configuration of some parameters from CI873
when the connection to the device is already established. For such devices,
when there is power reset for the ethernet switch or CI873 ethernet cable
removal and insertion, connection is re-established to the device followed by
configuration of the parameters. Since some of the parameters for such a device
is not configured, the "Internal Config Error" warning is shown.
To overcome this, perform the following:
– Perform a hot swap of CI873, the configuration is downloaded before the
connection is established. Hence all device configuration parameters are
accepted by the device and the Unit status does not displays the "Internal
Config Error" warning.
– Move that specific device to another position in Control Builder, and
download followed by changing it back to original position.
