Section 7 Technical Data
General Technical Data
The general technical data that need to be considered while Connecting to the
DeviceNet and EtherNet/IP devices are:
• CI873 communicates only on Auto negotiation. Due to this it is recommended
and mandatory to configure the switch port to which CI873 is connected as
Auto negotiation.
• For the CI873 to connect to the DeviceNet devices and EtherNet/IP devices, the
EDS file of the devices should have all the mandatory connection information
as mentioned in
Section , Device Import Wizard.
• Tag based Class 1 connection information should be available in the EDS file
of the Logix 5000 Controllers for communication with the CI873 as mentioned
in
Section , Device Import Wizard.
• The number of I/O modules that can be connected under EtherNet/IP or
DeviceNet device adapter type device is 63.
• The number of configuration parameters supported per EtherNet/IP or
DeviceNet device is 1000.
• The CI873 supports listen only connection with the EtherNet/IP device,
provided that there is already exclusive owner connection in the device.
• The CI873 does not support redundant owner connections for the EtherNet/IP
devices. That is, at the same time both primary and backup CI873 cannot
connect to the same assembly object of the EtherNet/IP device even though the
device supports such connections.
• Read Only and Monitoring Parameters in EDS file of the
EtherNet/IP/DeviceNet device are not supported. That is, DIW ignores such
parameters while generating the Hardware type from the EDS file.
