Speed is relative.  Especially in the world of industrial control.  1 millisecond look ahead features in the machine control world used be considered “cutting edge” (pun intended). The programmable controller, the standard of industrial control, has a speed of execution metric.  It is generally specified in thousands of instructions per millisecond.  At 1000 instructions every 2 […]

PAC hardware can be used in multiple domains, including logic, motion, drives, and process control. And the software programs all control and monitoring tasks of multiple domains. This feature enables the programs to “flow” as the requirements of the application dictate. Critical to any mechatronics system is the control. One of the newest controllers is […]

So when is a PC (personal computer) a PAC (programmable automation controller) or a PLC (programmable logic controller)? They are all the same. They all have microprocessors. They are all programmable. They are all available with hardware that is rated for industrial environments, shock, vibration, temperature extremes and various other requirements. They are all connected […]
