It’s easy to get ahead of ourselves when we talk about the Industrial Ethernet. You look at the ever-growing reality of the Industrial Internet of Things and the longstanding concerns for security in these networks and you start to take this level of connectivity for granted.
However, so many companies are only just starting their Industrial Ethernet journeys. As you upgrade your network, choosing the right cabling will be critical to ensure you don’t disrupt traffic in the process.
Choosing cables for standard office settings can be hard enough—but when you’re upgrading to Ethernet in an industrial setting, keep these 6 points in mind.
If you’re starting from scratch on Industrial Ethernet and you’re upgrading from a legacy T1 copper network, you might not be planning for massive capacity.
Your networking needs could be 100M Ethernet all the way through 1G, 10G and beyond. This is the point where you weigh your fiber/copper options and consider various cable categories (Cat 5e for 100M or 1G, up to Cat 7 for 10G). If you’re unsure about navigating all of the various cable abbreviations, check out this post on media conversions.
In a standard IT network, you can choose cables based on business application needs. But when you’re talking about a factory floor’s OT network, the environment is everything.
Consider the level of vibration that cables will have to withstand. Will you keep cables protected in a specific control room? In this case you might not need to find such a flexible cable because vibration will be minimized.
However, if your cables are exposed to oil, moderate vibration, chemicals and more on the factory floor, you’ll need a more durable option. And at the extreme end, any cables that exist on your machines will need the highest levels of flexibility due to increased corrosion and vibration.
After considering your environment, you’ll want to make a decision on the right jacket protection for the cables in your network. There are 4 main options to consider:
If you’re unsure of the right choice between shielded and unshielded cables, unshielded is the easier choice because it works in most environments.
However, if you’re expecting unusually high noise ratios in your environment and need cables that can withstand it, foil or braid shields can help you protect the integrity of network signals.
When you don’t have to worry about vibration in your environment, solid conductors will work just fine. However, you face a choice between twisted or bonded-pair options when vibration challenges call for stranded conductors.
Twisted conductors might save you some money, but they are susceptible to damage during implementation and can cause greater challenges with network mismatching. Bonded-pair conductors are more suited for rigorous manufacturing environments.
Many of your considerations come down to the ruggedness of specific cable choices. Regardless of the cables you assess for your environment, you need to understand performance in all of the following categories:
If you take all of these points into consideration and decide on the right cables for your environment, you’re on your way to implementing Industrial Ethernet. Your next step will be determining the best way to design a network that ensures guaranteed traffic, visibility, and security.
