6. REDUNDANCY WITH NX3030 CPU
Figure 175: Active IP method – NX5000
Parameters that must be configured in the Active IP method for the NX5000 Ethernet modules:
IP Address Active: Active PLC communication address. Replaces the IP address from the Non-Active PLCX
IP Address PLC A Non Active: PLCA communication address, when in Non-Active state
IP Address PLC B Non Active: PLCB communication address, when in Non-Active state
Subnetwork Mask
Gateway Address
6.3.11.4. Multiple IP
The Multiple IP method can be configured in the Ethernet interfaces from the NX5000 Ethernet modules. In this method
there’s an IP for each half-cluster and for each state of the PLC. The PLCA assumes an IP address when it’s Active and another
when it’s Non-Active. The same happens for the PLCB regarding its state (Active or Non-Active).

Parameters that must be configured in the Multiple IP method:
IP Address PLC A Active: PLCA communication address, when in Active state
IP Address PLC A Non Active: PLCA communication address, when in Non-Active state
IP Address PLC B Active: PLCB communication address, when in Active state
IP Address PLC B Non Active: PLCB communication address, when in Non-Active state
