Omron CS1W-ETN21 operation manual Using the ETN11- compatible Mode

IP Addresses in FINS Communications Section 5-2

Using the ETN11- compatible Mode

For Ethernet Unit with unit version 1.4 or later, operating specifications can be made compatible with the CS1W-ETN11/CJ1W-ETN11 for all methods (auto- matic generation (dynamic), I/O address table, or combined). (Dynamic changes, however, are prohibited for the destination IP address in ETN11- compatible mode.) While in ETN11-compatible mode, the following operations will be performed the same as they are for the CS1W-ETN11/CJ1W-ETN11 for FINS/UDP command data sent from a UDP port number other than the local FINS/UDP port number (default: 9600) set in the Unit Setup Tab Win- dow.

•If the command data is for the Ethernet Unit, a FINS response will be sent to the source UDP port number.

•If the command data is for any other Unit, such as the CPU Unit, a FINS response will be sent to the UDP port number set as the FINS/UDP port number.

The ETN11-compatible mode is set as follows using the Web function setting window.

1,2,3... 1. Connect to the Ethernet Unit from a Web browser and select Settings - 1. IP address and Protocols - System. The System Format will be displayed.

2.Select ETN11 compatible mode from the FINS/UDP option in the System Format, click the Set Button, click the Regist Button, and then turn the pow- er supply OFF and ON or restart the Unit using a software restart.

Note (1) If the ETN11-compatible mode is used, internal method tables will not be changed when the power supply is turned OFF and ON or software resets are executed. This provides protection from access via FINS/UDP from computers that dynamically change their IP address.

(2)The ETN11-compatible mode is not used for normal applications and should not be used in most cases.
