Updation of Scan List on DeviceNet Device Parameter Change
While re-configuration of a DeviceNet device, do not change the scan list
parameters, which are not associated with the connection trigger type to which
the DeviceNet device is configured initially.
For example, assume that the Poll connection trigger type is selected during
fresh configuration of DeviceNet device. During re-configuration, the scan list
parameters associated with the COS connection trigger type is changed, such
as Inhibit time and Acknowledgement time. These changed scan list
parameters are not associated with the Poll connection trigger type to which the
device is configured. Since, the CI873 does not verify whether the changed
parameters have any effect on the trigger type selected, the communication is
considered changed. As a result the scan list configured on the LD 800DN gets
updated, leading to the stoppage of communication in the DeviceNet network.
The Control Builder displays a warning indicating the break down of
communication.
Re-configuring DeviceNet Parameters on LD 800DN
Re-configuring the DeviceNet parameters on an LD 800DN does not disrupt
the flow of input data from the DeviceNet slave devices to the CI873. However,
the linking device has to be in Idle mode before modifying any configuration
data on it. There is no output data from the linking device to the DeviceNet
slave devices while the linking device is in Idle mode
Re-configuring LD 800DN by changing Baud Rate
If the baud rate of the LD 800DN is changed, then a matching baud rate change
should be made in all the DeviceNet devices connected to that LD 800DN. A
power recycle is then needed for these changes to take effect. A matching baud
rate change is not possible in DeviceNet devices which do not have any baud
rate option in its configuration parameters. As a result, such devices may
become incompatible with the LD 800DN's baud rate configuration. In such a
case, the error displayed is
CAN Bus Off
or
DeviceNet MAC ID
initialization in progress
.
Re-configuration of EtherNet/IP devices
When an EtherNet/IP device or EtherNet/IP modular IO is added /removed online,
then the communication with other EtherNet/IP devices will not be affected.
