Product Description The Allen-Bradley® MicroLogix™ 1400 from Rockwell Automation complements the existing MicroLogix family of small programmable logic controllers. MicroLogix 1400 combines the features you demand from MicroLogix 1100, such as EtherNet/IP, online editing, and a built-in LCD, plus provides you with enhanced features, such as: higher I/O count, faster High Speed Counter/PTO and enhanced network capabilities Take advantage of the built-in LCD with back lighting to set the Ethernet network confi guration, display fl oating point values on a user confi gurable display, display OEM logos at startup and read or write any binary, integer and long fi le elements in the data table. Three embedded communication ports provide you with excellent communications capabilities. MicroLogix 1400 off ers an isolated RS232C/ RS485 combination port; a non-isolated RS232C port; and an RJ-45 port for 10/100 Mbps EtherNet/IP peer-to-peer messaging, DNP3 over IP and Modbus TCP/IP protocol. Similar to the rest of the MicroLogix family, MicroLogix 1400 is programmed with RSLogix 500 programming software (Version 8.1 and above) as well as RSLogix Micro programming software.
Features and Benefi ts
• Expand your application capabilities with up to 7 expansion I/O modules for a maximum of 256 discrete I/O
• Up to 6 embedded 100 kHz highspeed counters (on controllers with dc inputs)
• 2 Serial ports with DF1/ DH485/ Modbus RTU/DNP3/ASCII protocol support
• Ethernet port provides you with EtherNet/IP, DNP3 over IP and Modbus TCP/IP protocol support as well as web server and email capabilities
• Built-in LCD with backlight allows you to view controller and I/O status, and provides a simple interface for messages, bit / integer monitoring and manipulation.
