2.1
Intended use
The Embedded PC is a modular control system and is intended for mounting on a DIN rail. The system is
scalable, so that the basic PC modules, power supply units, system modules and extension modules can be
assembled and installed in the control cabinet or terminal box as required.
The Embedded PC series is used in conjunction with Bus Terminals for recording digital or analog signals
from sensors and transferring them to actuators or higher-level controllers.
The Embedded PC is designed for a working environment that meets the requirements of 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.
Improper use
The Embedded PC is not suitable for operation in the following areas:
• Potentially explosive atmospheres.
• Areas with an aggressive environment, e.g. aggressive gases or chemicals.
• Living areas. If the devices are to be used in living areas, the relevant standards and guidelines for
interference emissions must be adhered to, and the devices must be installed in housings or control
boxes with suitable shielding.
2.2
Staff qualification
All operations involving Beckhoff software and hardware may only be carried out by qualified personnel with
knowledge of control and automation engineering. The qualified personnel must have knowledge of the
administration of the Industrial PC and the associated network.
All interventions must be carried out with knowledge of control programming, and the qualified personnel
must be familiar with the current standards and guidelines for the automation environment.
