Description
PROFINET-Switch IP67 managed 10 / 100MBit
One of the most important functions of a PROFINET-Switch is the prioritizing of the PROFINET frame traffic in the machine network. The managed switch can differentiate whether the frame is a web query, an FTP file transmission, a media stream, or a PROFINET frame. In the case of a high transmission load, the important frames can thus be prioritized in order to prevent frame losses. With a GSDML file you can integrate the switch into your automation environment in the usual way. The supported PROFINET protocols, such as LLPD, DCP, or even diagnosis alarms, can be easily configured and administered.
With its protection class IP67 and temperature range from -40 °C to +75 °C, the PROFINET Switch 8 Port, IP67 is ideal for use in rough industrial conditions. The product is ideally suited for installation without a control cabinet and therefore offers a wide range of applications.
Technical advantages when using a PROFINET-Switch:
- Prioritizing of PROFINET frames
- Assignment of a configuration via the device name
- Neighborhood detection

FAQ & SUPPORT
PROFINET-Switch IP67 managed 10 / 100MBit
Background
| Under certain circumstances, if an attacker with direct (physical) access to the PROFINET network attacks the devices using the DCP services of the PROFINET protocol, this can lead to a permanent loss of communication capability between the PROFINET controller and the PROFINET device. The reason for this lies in the nature of the DCP service provided by the PROFINET protocol. This DCP service can be used to change or reset device parameters via DCP command. Examples of this are DCP-Set (NameOfStation) or DCP-Set (Reset-to-Factory). No safety functions are provided for the use of DCP in the existing PROFINET specification. |
Impact
| Under certain conditions, an attacker – with direct access to the OT network – can prevent the PROFINET controller from establishing communication with a PROFINET device and thus disrupt the operation of the device. Manual intervention by the user is required. The device is not destroyed by an attack, it is simply no longer accessible to the CPU. A new assignment of the PROFINET name or IP address can restore device operation. |
Measures
| Helmholz recommends that its customers introduce or review a strict access policy for the network. Access from other zones to the PROFINET network must be restricted, in particular DCP services must be blocked. This can be achieved using a firewall or a suitable VLAN configuration.
Newer versions of the PROFINET specification address this problem by introducing PROFINET security in security class 1. Helmholz will successively implement PROFINET security class 1 for all active PROFINET components and make new firmware versions available. |
