EtherNetIP - ACD

“ACD” stands for Address Conflict Detection and is used to detect when multiple slaves on a network are using the same IP Address and a possible bus conflict could occur.


The P2CDS-622 Ethernet/IP Scanner (Master) or Adapter (Slave) will not be able to detect and record the presence of duplicate IP addresses. If this scenario were to occur, the devices connected would show in the device tree in the error state.

Data integrity will be compromised if there are duplicate addresses.


The user needs to ensure connected devices do not have the same/duplicate IP Address.
