check done depends on the Electronic Key parameters enabled. For more details on
the Electronic Key parameters, refer to Electronic Key Parameters on page 124.
For details on the ADR parameter, refer Configuring LD 800DN Linking Device
Unit on page 110.
For details on the parameter for Configuration Recovery, refer Configuring a
DeviceNet Slave Device Unit on page 122.
Hot Swap of EtherNet/IP Device
EtherNet/IP devices supports hot swap. Faulty units can be replaced online without
disturbing the communication with other EtherNet/IP slaves in the network.
When the DeviceNet IP device is removed and re-inserted, it shall be
re-configured only if the address recovery for the LD800DN and the Config
recovery for the device are enabled.
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, either from the LD 800DN Web interface,
or by any device specific configuration tools, for example, RSNetworks for
DeviceNet.
When wrong MAC ID is specified in the Control Builder configuration it is
detected through the MAC ID check and shown error on the linking device. But
the communication between linking device and DeviceNet devices happens at the
right MAC ID configured at the linking device level and the communication
between communication interface and linking device is using IP address so there
will not be any problem.
When the EtherNet/IP device is removed and re-inserted, it shall be re-configured
again by the CI873.
