IP the Wizard to detect the damaged equipment.
One of the main figures. Will be able to prevent large solids such as gravel. And even dust.
The second digit. Indicates the ability to prevent the liquid. Such as water or steam by a number, the more it means to be higher than it. (more…)
How to choose DCS or PLC for new automation system
Traditionally, users can choose between a PLC or a PLC / SCADA approach when selecting a control for use in the process. Richard Sturt, Rockwell Automation Business Development Manager, Process Industries, believes that Rockwell offers users a solution for the elements of both approaches.
An important advantage of the traditional DCS was that the supplier a “systems approach” and took it was designed for large applications. Much of the work of integrating different parts of the system was provided by the DCS vendor with a single database for the entire system. (more…)

Implement a network of wireless sensors on factory by standard control systems
The wireless mesh networks are designed to provide channels of communication bandwidth between sensor nodes have a wireless coverage area specific. Wireless nodes jointly making data transmission based on their “knowledge” of the network. In a mesh network each node can communicate with other adjacent nodes in the same area as they share the same network credentials.
A wireless node would normally be sent to its “parent.” If a node fails due to hardware failure or other reason, its neighbors are able to modify the route to transfer data to the next station.
Mesh networks use different communication protocols. A protocol is the vector ad hoc on demand (AODV) routing. When using AODV protocol network is quiet until a connection is required. When a node requires a connection broadcasts a request to connect to the network. Other nodes on the network broadcasts the request for registration in the same time, the ID of the requesting node. Assuming that the communication channels were initially put in place throughout the network, the receiving node sends a reply to the sender. Communication between stations is generally determined by the least number of “hops” through other nodes. When a communication link is not a routing error is returned to the original sending node and the process repeats. (more…)
