Industrial Wireless System

Are you seeking disruption-free industrial communication with reduced cabling needs? ​
As the sole supplier, SMC offers an industrial solution for wireless communication with valves and I/Os. The system is available in a modular version (EX600-W) and a compact version (EXW1) and is compatible with Ethernet/IP, PROFINET, EtherCAT and CC-Link.​

​

Why choose wireless?​

By using a wireless solution, you avoid production interruptions due to loose or broken communication cables or bad contacts. It eliminates errors caused by electromagnetic noise thanks to the better immunity of wireless communication. In addition, there are cost savings as it removes the need for ultra-flexible cables, special swivels, complex dress packs and so on.​

​

Advantages of SMC's wireless communication:​

  • Easy installation and reduced maintenance with less cables and connectors​

  • Reliable and safe communication with frequency hopping and data encryption on the 2.4GHz ISM band​

  • Suitable in demanding applications where cables and connectors are subjected to stress​

  • Perfect for disruption-free communication in welding applications since the system's signal handling is not affected by interference from the weld​

  • Simple and flexible machine layout and smooth tool change​

  • Cloud-based monitoring and control of production via OPC UA built into SMC's AMS20/30/40/60.

FAQs

What does the term “wireless” refer to?

Wireless is the transfer of information between two or more points that are not connected by an electrical conductor. In wireless systems, the transmission medium used is the air through electromagnetic radio signals. There are different wireless signals depending on the range of frequencies they occupy. Some wireless networks currently being used: - Wi-Fi: 2.4 GHz, 5.8 GHz - Bluetooth: 2.4 GHz - Wibree: 2.4 GHz.

Is wireless being used in factory automation?

The use of wireless communication in instrumentation and the control level of the automation system is considerably reduced when compared to other scopes. There is, however, a clear trend and interest to apply wireless solutions in automation systems as it provides several benefits:
- Savings related to the cost of cables
- Easier communication configuration
- Positioning the sensors in positions that cannot be reached with wired units
- The growth of information and reliability on redundancy as more sensors can be installe

Is the communication response as reduced as far as 2 ms?

Theoretically, the signal response time could be as low as 2 ms. However, although the system can communicate every 2 ms, it cannot send information every 2 ms. The real communication response will vary depending on the number of remotes connected to one base and the effect of the frequency hopping, as such the system is suitable for an application where the response time is not critical. In short, what it is really important for customers is the reaction time, a time that depends on the number of connected devices and other factors.

What is frequency hopping or FHSS?

FHSS refers to Frequency Hopping Spread Spectrum, and is a communication technology that consists of rapidly changing the frequency used for transmission to another frequency, so as to prevent interferences from other wireless equipment.
When the frequency that is being used is also being used by for example WiFi, or any other radio wave signal, the frequency hops or switches to another frequency. In this case, the frequency is hopping every 2 ms.
Given that the frequency is changing continuously, this communication method is resistant to radio wave interferences due to reflections or noise from other wireless equipment, while ensuring a high level of data security. With this method, a multiple wireless system can be installed in the same area, and it is a suitable technology for point-to-multipoint communication.
