  1761-NET-AIC, 1761-NET-ENI, and the 1761-NET-ENIW, these controllers provide the power for the interface converter modules. The MicroLogix 1400 does not provide 24V DC communication power through communication ports. Instead these pins are used to provide RS-485 communications directly. Any AIC+, ENI, or ENIW not connected to a MicroLogix 1000, 1200, or 1500 controller requires a 24V DC power supply.

  Channel 1 RS-232/485 Ethernet (DH485, DF1, or ASCII) (10/100Base-T) MicroLogix 1400 Actual performance of an MicroLogix 1400 controller varies according to: • size of Ethernet messages. Performance • frequency of Ethernet messages. Considerations • network loading. • the implementation of and performance of your processor application program.

• Page 367: Micrologix 1400 And Pc Connections To The Ethernet Network

  The MicroLogix 1400 Ethernet connector conforms to ISO/IEC 8802-3 STD 802.3 and utilizes 10/100Base-T media. Connections are made directly from the Connections to the MicroLogix 1400 to an Ethernet hub or switch. The network setup is simple and Ethernet Network cost effective. Typical network topology is pictured below.

• Page 368: Cables

  • Use the auto negotiation function for both the switch port and the MicroLogix 1400 Ethernet port • If you want to force to a specific speed/duplex mode, you must force both the MicroLogix 1400 Ethernet port and the switch port to the same setting. Cables Shielded and non-shielded twisted-pair 10/100Base-T cables with RJ45 connectors are supported.
