The global cellular network allows you to access your machines and systems at any time and anywhere.
For the continuous acquisition of your process data, Phoenix Contact offers cellular devices which support all carrier technologies, from SMS texts through to data communication via GPRS/EDGE (2G), UMTS/HSPA (3G), and LTE (4G). With the globally available cellular network, the devices become a reliable communicator, even in areas with a weak infrastructure.
The smallest remote stations and entire system parks, such as remote pumping stations, can be connected to the control center using methods spanning from SMS messaging, through remote control protocols at low-data rates, all the way to broadband VPN connection, depending on the communication requirements.
Cellular technology provides a secure communication solution for applications with a large data throughput. In an LTE network, monitoring images and server functions are made available to the control center from around the globe.
The routers with VPN functionality make closed communication on the Internet possible. The data traffic can be transmitted directly to the control room via VPN. Thus, for example, it is possible to connect wind turbine generators via camera applications, or to connect to the network of a sewage treatment plant.
SMS technology is ideally suited for a low number of switching operations or a large number of different actuators. A remote process can be controlled via SMS commands with a pre-paid card without being bound to a contract.
Using the SMS version of the TC MOBILE I/O X200 remote control system, access controls can be implemented with an ordinary cellphone by activating the door lock release system or systems can be reactivated in the event of an error. The I/Os of a controller can be connected via SMS or the VPN tunnel can be initialized on demand through the existing software interface of the cellular routers.
Special security directives apply to critical applications, such as the distribution of water, gas, oil, and electricity. In such applications, communication over public networks is often completely prohibited.
Many providers offer SIM cards that use a private APN (Access Point Name). With this method, a private network can also be established through the cellular interface, and a distributed LAN (Local Area Network) is created. In contrast to the public cellular network, fixed IP addresses can be used, allowing direct communication between the substations. When using this approach, an attempted Internet attack on critical applications is impossible.
