Intended use

With the CU8210-D004-0200 4G USB stick, Beckhoff Industrial PCs can be equipped with a GSM/UMTS/LTE modem and subsequently connect to a mobile communication network. The USB stick can also receive and send text messages using the Short Message Service (SMS).

The 4G USB stick was developed for a work environment that conforms to protection class IP20. This involves finger protection and protection against solid foreign objects up to 12.5 mm, but not protection against water. Operation of the devices in wet and dusty environments is not permitted, unless specified otherwise. The specified limits for electrical and technical data must be adhered to.

The 4G USB stick is used to:

• equip Industrial PCs with an internet connection in rural areas without a comprehensive wired infrastructure;
• establish a mobile communication connection between devices over long distances,
• or to reach difficult to access machine or plants such as wind turbines more easily. In addition, service technicians can check the status of a plant with the help of a direct connection to the Device Manager or a remote connection.

Improper use

The 4G USB stick is not suitable for operation in the following areas:

• areas in which the use of radio devices is prohibited.
• Potentially explosive atmospheres.
• Areas with an aggressive environment, e.g. aggressive gases or chemicals.
• applications that require real-time communication via radio.
