Copper, Fiber optics or WiFi?
Useful guidelines for designing your onsite communication network
We generally employ wireless protocols in cases where the backbone has already been established and additional equipment need to be added, or where trenching and racking are not economically or physically feasible such as river crossings.
Conclusion
We strongly recommend fiber optics for all SCADA systems where cable runs approach 100m or where there is a chance of electromagnetic interference. A ring topology is preferred because of its redundancy features and ease of diagnostics. Copper cabling should be used for short cable runs and inside buildings, and wireless communication devices limited to cases where additional equipment needs to be added to existing networks. In conclusion, it cannot be overstated that a thorough Network Design is the key to a robust and trouble-free SCADA system.
This forms part of our normal scope of supply and is conducted in close collaboration with the customer. Start thinking about your Network Design as early on in the planning process as possible.
