When using programmable logic controllers as well as when using operating and monitoring devices as control
systems in conjunction with a Soft PLC (e.g. B&R Automation Runtime or similar product) or Slot PLC (e.g. B&R
LS251 or similar product), the safety measures that apply to industrial controllers (protection by protective equip-
ment such as emergency stops) must be observed in accordance with applicable national and international regu-
lations. This also applies to all other connected devices, such as drives.
3 Transport and storage
During transport and storage, devices must be protected against undue stress (mechanical stress, temperature,
humidity, aggressive atmosphere, etc.).
Devices contain components sensitive to electrostatic charges that can be damaged by improper handling. It is
therefore necessary to provide the required protective measures against electrostatic discharge when installing
or removing these devices.
4 Operation
4.1 Protection against contact with electrical parts
Before switching on programmable logic controllers, operating and monitoring devices and uninterruptible power
supplies, it must be ensured that the housing is properly connected to ground potential (PE rail). The ground
connection must also be made if the operating and monitoring device and uninterruptible power supply are only
connected for testing purposes or only operated for a short time!
4.2 Ambient conditions - Dust, moisture, aggressive gases
The use of operating and monitoring devices (e.g. industrial PCs, Power Panels, Mobile Panels) and uninterruptible
power supplies in dusty environments must be avoided. This can otherwise result in dust deposits that affect the
functionality of the device, especially in systems with active cooling (fans), which may no longer ensure sufficient
cooling.
The presence of aggressive gases in the environment can also result in malfunctions. In combination with high
temperature and relative humidity, aggressive gases – for example with sulfur, nitrogen and chlorine components
– trigger chemical processes that can very quickly impair or damage electronic components. Blackened copper
surfaces and cable ends in existing installations are indicators of aggressive gases.
When operated in rooms with dust and condensation that can endanger functionality, operating and monitoring
devices such as Automation Panels or Power Panels are protected on the front against the ingress of dust and
moisture when installed correctly (e.g. cutout installation). The back of all devices must be protected against the
ingress of dust and moisture, however, or the dust deposits must be removed at suitable intervals.
4.3 Programs, viruses and malicious programs
Any data exchange or installation of software using data storage media (e.g. floppy disk, CD-ROM, USB flash
drive) or via networks or the Internet poses a potential threat to the system. It is the direct responsibility of the user
to avert these dangers and to take appropriate measures such as virus protection programs and firewalls to protect
against them and to use only software from trustworthy sources.
5 Security concept
B&R products communicate via a network interface and were developed for integration into a secure network. The
network and B&R products are affected by the following hazards (not a complete list):
•
Unauthorized access
•
Digital intrusion
•
Data leakage
•
Data theft
•
A variety of other types of IT security breaches
It is the responsibility of the operator to provide and maintain a secure connection between B&R products and the
internal network as well as other networks, such as the Internet, if necessary. The following measures and security
solutions are suitable for this purpose:
•
Segmentation of the network (e.g. separation of the IT and OT networks)
•
Firewalls for the secure connection of network segments
