The annual Automation Fair is a highly influential professional exhibition held by Rockwell Automation in North America, including presentations, lectures, and more. It was held in Chicago in mid-November this year. The city is one of the most important manufacturing centers in North America and the location of the editorial department of CONTROL ENGINEERING.
Scott J. Johnson, Rockwell Automation Network Product Specialist, gave a report titled "10 Commandments for Industrial Ethernet to Control Tasks" in this year's lecture. I think it is also inspiring for Chinese users. value. He believes that the most common error in using Industrial Ethernet for control tasks is the choice of the switch. At the same time, it is important to remember that hubs cannot be used in the network.
Among the 10 precepts described by Scott J. Johnson, the following lists the most valuable points:
â–  Fully understand the needs of your system. Including work environment, I/O control, integration to the IT layer, scalability, security, performance, data traffic size, transmission speed, distance, transmission media, switches, routers, firewalls, etc.
â–  Understand the environment of the system. The key is to understand whether the control network is integrated with the company's IT network or is isolated. If it is integrated, there are many factors to consider when controlling network design and implementation, especially in terms of security, traffic, and IP address.
â–  IT personnel must be fully aware of the needs and conditions at the field level. For example, which party is responsible for network maintenance and management, and whether to adopt a unified IP address, what are the respective responsibilities of both parties? Such problems need to be communicated and resolved; at the same time, to ensure that IT personnel understand that I/O data streams are multicast.
â–  Correct network segmentation. This can greatly simplify the management and security of the network.
â–  You cannot use a hub.
â–  Choose the right performance switch, whether it is a managed or unmanaged switch, while the managed switch involves port mirroring, IGMP snooping, port diagnostics and many other considerations.
â–  Select the correct physical media. Copper, twisted pair or fiber? Different physical media have their own characteristics.
