OMRON products are manufactured for use according to proper procedures by a qualified operator and only for the purposes described in this manual. The following conventions are used to indicate and classify precautions in this manual. Failure to heed precautions can result in injury to people or damage to property.
Indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury. Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury. [. . . ] Frames that include private IP addresses are restricted by the router from being sent outside the LAN. Generally, as shown below, global addresses in the intranet are allocated only to IP routers (such as broadband routers) interfacing with the Internet. All other nodes in the intranet, including the Ethernet Unit, are allocated private addresses.

Communications Services That Require Global Addresses for Ethernet Units
A global address is required for the Ethernet Unit's IP address when the following communications services are used over the Internet. · FINS communications services · File transfers · Socket services When mail is sent or received over the Internet, the Unit's IP address can be a private address.

Conditions for Using Communications Applications 1, 2, 3. . .
When the Ethernet Unit has a private address, communications applications can be used under the following conditions: 1. FINS Communications Service · FINS communications service is enabled only between Ethernet Units with private addresses on the intranet. A device such as a personal computer (with a FINS application including a CX-Programmer) cannot connect online and communicate over the Internet with an Ethernet Unit that has a private address. FINS communications over the Internet are also not possible between Ethernet Units with private addresses. · Either FINS/TCP or FINS/UDP can be used for the FINS communications service. · With FINS/UDP, all of the Ethernet Unit IP address conversion methods can be used.
Private and Global Addresses
· With FINS/UDP, when the IP address (private address) of a computer serving as a DHCP client is changed, the Ethernet Unit's IP address conversion method will be the automatic generation method (dynamic), the combined method, or the IP address table method. When FINS/TCP is used, IP addresses can be changed automatically.
2. Transferring Files · Files can be transferred, using FTP protocol, between the PLC and a device such as a personal computer (i. e. , an FTP client) with a private address on the intranet. · The TCP port number to be used for FTP cannot be used if prohibited by a firewall in the communications path. Sending Mail The PLC can send the Ethernet Unit's IP address to the SMTP server by mail via the intranet. Receiving Mail The PLC can receive the Ethernet Unit's IP address from the POP3 server by mail via the intranet. Automatic Clock Adjustment The PLC can acquire clock data through the Ethernet Unit's IP address from the SNTP server via the intranet. Host Name Designation The PLC can acquire the server IP address for the Ethernet Unit's IP address from the DNS server via the intranet. Note Network Security and Firewalls Setting up an intranet through a global address involves network security considerations. Before doing so, be sure to consult with a network specialist and consider installing a firewall. Once a firewall has been set up by a communications company, on the other hand, there may be some applications that cannot be used.
