Las Communication Networks in Industry They facilitate the description of a type of transmission system that facilitates the exchange of information among the various components that make up these networks. A connection is established between the different levels of the factory, from the offices to the machines that manufacture the product.
In this post, we're going to talk about the CIM Pyramid in Industrial Communication so that you can understand where it all begins and the different stages that communication goes through.
Organization of the Industrial Pyramid
One could talk about two clearly distinct layers. En the lower part We work with a large volume of data, where there is no control whatsoever, and the broadcast times are quite high. But as we get closer to the upper part, where the product reaches its peak, there are fewer transmissions because the product is practically complete; there is complete control, and less time is spent on data transmission, but it is done in a decisive and thorough manner.
Everything I'm telling you is governed by the pyramid CIM (Computer-Integrated Manufacturing), where the levels of a fully automated factory are defined. These can be summarized as follows:
Factory or management level
Among the components that make up the system are servers and computers. It is the level of information, where a large amount of data is received and company managers begin to shape the product they want to launch. Communications between them must be capable of transmitting large amounts of data, which is why networks are used Ethernet standard with protocols TCP/IP.
Floor level
Es the level at which the supervisory function is located by the various control systems. Communication is established between systems and monitoring devices, which again requires Ethernet networks using the TCP/IP protocol.
Cell level
Es the level at which orders from superiors are received and broken down into simpler orders to pass them on to lower levels. From this point on, communication must be more specific yet robust; that is why we begin working in real time with industrial Ethernet networks.
Field Level
Es the level at which the sensors are managed on the lower level. It features the PLC’s, robots, and control cards. This level requires control networks rather than data networks (ControlNet, ProfiNet, etc.).
Process or instrumentation level
Este es the level at which the commands of the elements that control the process are executed. There is direct interaction with the higher level, and everything happens in real time. At this point, the machines are already fully programmed, and there is very little room for human interaction—only for analyzing and resolving any errors that arise.
For all these reasons, the CIM Pyramid in Industrial Communication It is a very well-defined tool that includes all the necessary parameters to ensure the product meets the specific end goal.
