801-CMC21 A-B  Control Unit

MicroLogix 1400 controllers provide three communications ports: an isolated combination RS-232/ RS-485 communication port (Channel 0), an Ethernet port (Channel 1), and a non-isolated RS-232 communication port (Channel 2). You can connect Channel 0 and Channel 2 ports on the MicroLogix 1400 controller to the following: • Operator interfaces, personal computers, and so on, with DF1 full-duplex point-to-point • A DH-485 network • A DF1 Radio Modem network • A DF1 half-duplex network as an RTU master or RTU slave • A Modbus network as an RTU master or RTU slave • An ASCII network • An Ethernet network using the Ethernet Interface module (catalog number 1761-NET-ENI, or 1761-NET-ENIW) • A DNP3 network as a slave

When connecting to an RS-485 network with DH-485, DF1 half-duplex master/slave, Modbus RTU master/slave, or DNP3 slave protocols, you can connect the MicroLogix 1400 controller directly via Channel 0 without an Advanced Interface Converter, catalog number 1761-NET-AIC. The Channel 0 combo port provides both RS-232 and RS-485 isolated connections. The appropriate electrical interface is selected through your choice of communication cable. The existing MicroLogix 1761 communication cables provide an interface to the RS-232 drivers. The 1763-NC01 cable provides an interface to the RS-485 drivers. You can also connect the controller to serial devices, such as barcode readers, weigh scales, serial printers, and other intelligent devices, using ASCII. See Default Communication Configuration on page 57 for the configuration settings for Channel 0. MicroLogix 1400 controller can be connected directly to the RS-485 network via channel 0, using ASCII. The MicroLogix 1400 supports EtherNet/IP™ communication via the Ethernet communication Channel 1. In addition, either Modbus TCP or DNP3 over IP can be enabled for Channel 1. You can connect your controller to a local area network that provides communication between various devices at 10 Mbps or 100 Mbps. This port supports CIP explicit messaging (message exchange) only. The controller cannot be used for CIP implicit messaging (real-time I/O messaging). The controller also includes an embedded web server that allows viewing of not only module information, TCP/IP configuration, and diagnostic information, but also includes the data table memory map and data table monitor screen using a standard web browser.
