MicroLogix 1000 Controllers

Communication

Point-to-Point—RS-232 communication port configurable for direct connection to your programming device.
DH-485—RS-232 communication port configurable for DH-485 communication through an AIC+ (1761-NET-AIC) converter. Lets you communicate with SLC 500 processors, other MicroLogix controllers, operator interfaces, or programming devices in a DH-485 network.
EtherNet/IP—RS-232 communication port configurable for EtherNet/IP communication through an EtherNet/IP-to-RS-232 interface (1761-NET-ENI). The 1761-NET-ENI supports program monitoring and upload/download, data collection from PCs or mainframes, and controller peer-to-peer communication. It can also send e-mail messages via SMTP (Simple Mail Transfer Protocol), and can display status and configuration information through a built-in Internet server.
DeviceNet—RS-232 communication port configurable for communication through a DeviceNet interface (1761-NET-DNI) lets the controller function as a slave node in a DeviceNet network or as a peer to other controllers also using the 1761-NET-DNI interface.
DF1, half-duplex—RS-232 communication port configurable for DF1 half-duplex slave protocol for connection to a modem in SCADA applications.
