NX-series Communications Interface Units NX-CIF CSM NX-CIF DS E 8 1 Provides simplicity and flexibility in connecting serial devices to EtherCAT Mount to the NX-series EtherCAT Coupler Unit and connect various types of serial devices. The serial line monitor on the Sysmac Studio helps easily and reliably connect serial devices. Features Just 12 mm wide, saving space in your cabinet. Three models are available with a choice of one RS-422A/485, one RS-232C, or two RS-232C ports. Screwless push-in terminal block (1-port model) and D-Sub connector (2-port model) significantly reduce wiring work. No-protocol communications are supported as the communications protocol. The maximum baud rate is 230.4 kbps. The baud rate can be selected to match the connected serial devices. The settings are backed up and saved in the EtherCAT Coupler Unit. This facilitates commissioning and maintenance. The serial line monitor enables you to check the communications status with serial devices on the Sysmac Studio for easy and reliable startup of the devices.
