Modern computer numerical control machines called CNCs, allow you to connect to a teleinformatics network or as most prefer a computer. The most common question we receive is what is a teleinformatics network used for?

A teleinformatics network saves time and avoids a number of unnecessary and time-consuming activities. Here’s a list of all of the benefits to connecting your machines tools to a network:

  • The network allows you to remotely transfer technology from the server to the individual components. The server also allows you to manage digital versions and thus track their changes.
  • Using a network is faster, more reliable, and prevents damage to or destruction of a control program transferred from a device such as a pen drive.
  • You can have electronic delivery of production orders such as an MRP or MES.
  • You can monitor a machine’s working time.

The teleinformatics network on the production floor is not a computer network you would use at home to which we would connect a printer, scanner, or perhaps even TV set. Its proper design and topology should take into account the goals to be achieved (transferring programs, monitoring, etc.) as well as security of access and use. It is a myth that the connection of a CNC machine’s tools allows them to be accessed from anywhere on the Internet. However, it does depend on the topology design, applied solutions, and security used.

So, once again, the teleinformatics network on the production floor is not a home or office network. Exploitations and different environmental requirements also affect the way it is designed and built. So, what should characterize the network?

  • Resistance to currents straying.

    Especially if cables are placed in ducts where a CNC machine’s power supple cables run. This prevention can be achieved through the use of shielded cables or constructing a fiber optic network. (Complete resistance to drive and wiring, as well as wandering currents with a Fiber network is only 20% more expensive.)

  • Connectivity stability and the ability to remotely monitor the entire infrastructure.

    Let’s not forget that an IT network includes many other things including switches and hubs, routers, and firewalls.

  • Adequate bandwidth and access times.

    Because there are not large amounts of data being sent over the network, the industrial network does not need to have the highest data transfer rates. It should be noted, however, that depending on the network’s topology and expected response times, relatively new (and therefore expensive) solutions are usually used. Additional, this network is built “for the future” and not simply just for the here and right now.

Most importantly, most modern CNC systems are equipped with network cards as standard; older versions, however, may require the purchase of an additional expansion card or license for it such as a Siemens Sinumerik.
