Developing high performance data acquisition and control systems takes better tools than the industry normally provides. As the most common controllers, PLCs can be still weak in many applications, and especially they are not good choice for data acquisition due to their limited capability of computation, speed, memory and programming constraints. The fact that today s PCs have many advantages compared with their relatively low price made them very popular in industrial environments. In this project a PC based controller was designed for data acquisition and control purposes. Although such similar systems exist, this product with some advantages could be a good alternative to the existing ones.
