Configuration of IP Address is Required Before Using Ethernet Communications
The Ethernet interface within the CPU module cannot operate on a network until a valid IP address is
configured. The necessary Ethernet addressing information must be configured prior to actual network
operation. Use one of the following methods:
■
Perform the initial configuration using a PLC Programmer connected through the PLC power supply
serial port.
■
Connect a serial terminal to the station manager port of the CPU374. Then use the CHSOSW command
to enter a temporary IP address. The Ethernet Interface can then be accessed over the network (such as
by an Ethernet PLC Programmer). For details, see the TCP/IP Ethernet Communications Station
Manager Manual, GFK-1186.
■
Temporarily assign an IP address to the module using the Ethernet network. For details, see the TCP/IP
Ethernet Communications Station Manager Manual, GFK-1186, Appendix D.
Proper IP Addressing is Always Essential
The CPU374’s embedded Ethernet Interface must be configured with the correct IP Address for proper
operation in a TCP/IP Ethernet network. Use of incorrect IP addresses can disrupt network operation for the
CPU374 and for other nodes on the network. Refer to the TCP/IP Ethernet Communications for the Series
90 PLC User’s Manual, GFK1541 for important information on IP addressing.
CPU374 May Unexpectedly Consume EGD Exchanges Produced To a Group Address
The CPU374 consumes EGD exchanges based solely on their producer ID and exchange ID. Unlike other
GE Fanuc products, the CPU374 does not filter consumed exchanges based on the IP multicast group
address. Group numbers must not be used as the means of distinguishing EGD consumers when using the
CPU374.
Ethernet Programmer May Briefly Lose Communications When Configuration Stored
Storing a PLC configuration containing Ethernet configuration values may require the Ethernet interface to
restart itself in order to use any changed configuration values. When the Ethernet interface restarts, an
