ROCKWELL Automation has added two controllers to the Allen-Bradley CompactLogix line. The CompactLogix 1769-L32E provides cost-effective EtherNet/IP connectivity, while the CompactLogix 1769-L31 allows stand-alone control.
A scaled-down version of the previously released 1769-L35E, the Allen-Bradley CompactLogix 1769-L32E controller creates a more economical solution for less complex applications. It includes I/O memory capacity of 750kb, with support for 16 local I/O modules and removable CompactFlash to enable fast, portable program archival and recovery options. Integrated 10/100 Mbps EtherNet/IP connectivity delivers high-speed data throughout for distributed I/O, HMI and data collection. These features make the L32E controller suitable for material handling, high-speed packaging and water/wastewater applications.
The CompactLogix 1769-L31 brings the Allen-Bradley Logix platform to a stand-alone controller, expanding features, power and performance over the previously released CompactLogix 1769-L30. The L31 has twice as much memory, twice the speed and more backplane throughput than the L30. In addition, the CompactLogix 1769-L31 provides dual serial ports, which allow users to communicate with two different types of equipment and it supports DF1, ASCII and Modbus master and slave protocols. It is suitable for stand-alone packaging and material handling machine control, plus oil/gas and water/wastewater SCADA applications.
