Choosing the most effective controller requires careful evaluation of multiple requirements.
Industrial controllers are using commercial off-the-shelf (COTS) technologies such as Ethernet, field-programmable gate arrays (FPGAs), USB, and MicroSD cards to improve price/performance ratios, shrink form factors, and add new features.
Picking the right hardware is critical, but users also need to make sure they include controller programming software in the evaluation process.
When selecting a PLC or PAC, specify the controller that best fits the applications. The controller specified should be based on controller capabilities and the application requirements, such as machine control, motion control, process control, test and data acquisition, distributed control, enterprise connectivity, or some combination.
