This paper addresses the design and implementation of a wireless network. proposed as a cost-effective support platform for PLCs. With this network. one or more supervising stations may access remote equipment like PLCs. An applicable communication methods are described and we applied efficient method among them to PLCs communication. The paper specifies these requirements and indicates methods to fulfill them. Also. it provides to the model of operation, and focuses on the implementation approach. The hardware and software design is described together with a number of critical points related to wireless communication on the Cnet. Furthermore, a discussion on system expandability and performance is tackled and some observations are stated. The main conclusion is, that the proposed method can feature good performance under normal operating conditions.
