Product DescriptionThe Omron CJ1W-ETN21 (CJ1WETN21) is a control module with Ethernet from the CJ1 series. This control module may be mounted on a DIN rack and secured to the rack by the deploying of the mounting pin on the control module. When connecting with other modules, the CJ1W-ETN21 control module can connect with other modules by the connectors placed on the sides of each module and sliders added on the top of the modules.
The CJ1W-ETN21 control module, when it is participating in the CS-series PLC, can link to a hub with the 100Base-TX cable (the 10Base-T is also acceptable). This cable is an unshielded twisted pair that can maintain speeds of 100Mbps. The greatest length the cable can be is 100 meters. Additionally, the ETN21’s cable’s modulation method is a baseband (as signified by the ‘Base’). This allows the module to communicate PLCs from the CJ system, CP1H system, and NSJ system. It can also connect with a host computer that is capable of running a CX-programmer, CX-integrator, SYSMAC Gateway, and FinsGateway.
The CJ1W-ETN21 connects with the modules system and 100Base-TX cable by the Ethernet connector which is integrated in the control module. There are three switches placed on the module, the first is a unit number switch which sets the number that the module will be positioned in the system. The other two node number switches of the CJ1W-ETN21 which sets the module’s FINS node number. On the side of the module there is a 12 digit Ethernet address, there are also ten indicator lights on the module.
