PAC products combine the functionality and openness of PC, the reliability of a programmable logic unit like PLC and the intelligence of I/O modules with flexible software tools for a wide range of applications from data acquisition, process control, motion control to energy and building management. Our PAC family includes FreeRTOS PACs for different requirements in OS, CPU and development platforms. The P10 - P12 gateways are based on STM32 ARM Cortex-M4 .
