Ip Address Duplication Error - Mitsubishi Electric RD78G4 User Manual

IP address duplication error

If one network has stations with the same IP address, duplication is detected.
• If there is already a station with the same IP address when adding a slave station, IP address duplication (error code
2160H) is detected in a station to be added and data link cannot be performed. (Other stations continue data link.)

Precautions
When the slave station that has already been connected (linked up) with TSN hub is to be added to each TSN HUB, IP
address duplication is not detected in a station to be added. If IP address duplication (error code 1802H) is detected in the
master station, disconnect the relevant slave station from the network. Otherwise, multiple stations with the same IP address
will exist on the same network, possibly leading to transient transmission being sent to an unintended station.
• If the startup processing of cyclic transmission is executed by powering off and on the master station, when a station with
the same IP address is in the network, IP address duplication (error code 3021H) is detected in the master station and data
link cannot be performed.
192.163.3.0
• During cyclic transmission, IP address duplication is regularly checked in the master station. When there are overlapping IP
addresses, IP address duplication (error code 1802H) is detected in the master station and cyclic transmission cannot be
performed with the relevant slave station. (Other stations continue data link.)
• IP address duplication between an Ethernet device and a CC-Link IE TSN device, and IP address
duplication between Ethernet devices are not detected at cyclic transmission startup of the master station.
• Station No. duplication is not detected.
Methods of recovery from IP address duplication
If IP address duplication is detected in the master station (error codes 1802H, 3021H), change the IP address of the
corresponding station, and power off and on the master station, or reset it.
