Network Symbols (CJ2H-CPU6@-EIP and CJ2M-CPU3@ Only)

Overview
Tags can be used from exterior devices to access the I/O memory of the local CPU Unit through the
network symbols defined in the CPU Unit. The CJ2 CPU Units have an internal tag name server that
can convert network symbols to actual I/O addresses, and so it is possible to access the CPU Unit's I/O
memory from the outside by using tags to access network symbols.
Network symbols can be used for the following applications.
• Data links with other PLCs on EtherNet/IP
• Tag access from outside with host or PT.
Set the network symbols in the global symbols tables of the CX-Programmer.
PLC
NS-series PT
Host computer
Additional Information
Refer to the EtherNet/IP Units Operation Manual (Cat. No. W465) for the procedures to create
tag data links.
