Control System Manages Parallel Tasks
October 10, 2006
Features of the sigmaPAC include a multi-function platform equipped with control functions for variables such as temperature, pressure, flow, level and position; logic and sequence functions; and process calculations. Targeted for applications with multiple parallel tasks to be managed by the same control unit, the control system has various interface ports, including RS232 and RS485, Ethernet and major Fieldbus types. It mounts on standard DIN rail and connects to remote modules using standard Ethernet cables with RJ45 connectors. The processor has 32-bit ARM architecture, 4 MB flash memory, 16 MB DRAM and 128 kB SRAM with battery backup.
