Section 5 Run-Time Operation
This section describes the run-time behavior of DeviceNet device, LD 800DN
linking device, and EtherNet/IP device, and provides guidelines for operating these
devices during re-import and re-configuration.
Run-Time Behavior
The run-time behavior of DeviceNet device, LD 800DN linking device, and
EtherNet/IP device are:
•
When a DeviceNet device configured in Control Builder, does not match with
the DeviceNet device available in the network, the device status shown in
Control Builder is
I/O Connection Error
and not
Wrong Device Type.
•
If the connection between LD 800DN and CI873 is lost or connection between
LD 800DN and configured DeviceNet slaves is lost, then IEC 1131 variables
connected to input channels of DeviceNet slaves get set to last good value.
•
Consider an LD 800DN, with either DeviceNet devices or Modular I/O devices
is configured under it. On checking the diagnostic information channel of the
LD 800DN in Control Builder, there may be increase in the value of
Number of
lost EtherNet/IP messages
on the LD 800DN. To reduce the number of lost
message packets, increase the Requested Packet Interval (RPI) value. The RPI
value can be increased from 10 (minimum) to 500 (maximum). By increasing
the RPI value, it helps in reducing/stopping the increase in the number of lost
packets.
•
Error is not set for EtherNet/IP and DeviceNet devices if the configuration is
cold downloaded or CI873 is hot swaped with its Ethernet cable removed.
However, if the cable is removed during run time, all the slave devices under
CI873 are updated with the connection related status.
