MicroLogix 1100 Controllers
Communication
The MicroLogix 1100 controllers provide an isolated RS-232C/RS-485 port and an RJ45 Ethernet port. The ports can be used for the following types of communication.
| Communication | Description |
| Communication channel 0 Isolated RS-232C and RS-485 electrical compatibility (on separate pins) |
• Use the RS-485 cable (1763-NC01) to interface directly to RS-485 networks. • DF1 full-duplex, DF1 half-duplex master and slave, DF1 radio modem. • DH-485; If you use RS-232C port and existing cables, an Advanced Interface Converter (1761-NET-AIC) and external power is required for networking. DH-485 is also supported directly using the RS-485 cable (1763-NC01) on this port. • Modbus RTU master and RTU slave; If you use RS-232C port and existing cables, an Advanced Interface Converter (1761-NET-AIC) and external power is required for networking. Modbus RTU networking is also supported directly using the RS-485 cable (1763-NC01) on this port. • ASCII. |
| Communication channel 1 RJ45 port supports EtherNet/IP for peer-to-peer messaging |
• 10/100 Mbps port with support for BOOTP and DHCP capability directly from the controller. • Automatically assign IP address through DHCP or BOOTP, or configure using RSLogix 500 programming software. • Monitor your IP address through the LCD Display (or use the write-on nameplate). • Supports CIP. • Allows controllers to exchange data with other controllers through messaging; does not support scanning of I/O on Ethernet adapters. |
