Key features

Performance and deployment

samosPRO allows the implementation of compact, fast and modular safety solutions for applications in mechanical and system engineering.


The programming is carried out with the software samosPLAN that is available in the download area of the VIPA homepage.
The programming software supports you during programming via a graphic device configuration and an intuitively easy to operate functional diagram editor. In the certified function block library there are standard logic blocks AND, OR, NOT, XNOR, XOR as well as application specific logic blocks like emergency stop, two-hand, muting, pressing, mode selector, reset and re-start. Up to 255 of these logic blocks are deployable in a project.


The system configuration including the system programs of the entire samosPRO systems is only stored in the program removable storage SP memory. This offers the advantage that the samosPRO system does not have to be reconfigured after the replacement of the connection modules.


Up to four samosPRO controller modules can be safely networked via the EFI interface. The connection with the standard VIPA controller is made via fieldbus gateways for PROFIBUS or PROFINET. The integration into other networks is made via gateways for CANopen, Modbus/TCP and Ethernet/IP. Up to two gateways can be connected to a controller module. The signal status (variables) can be replaced bi-directionally via these gateways. Gateways that are based on Ethernet additionally allow an online access including programming and remote maintenance.

Structure and concept

samosPRO is a fast, compact, modular safety controller for monitoring and controling mechanical and system engineering applications.
The system enables complete and economic safety solutions that are more flexible than conventional relay technology.
The graphic device configuration and a functional diagram editor with extensive certified function block library ensure convenient and clear programming.
The modular design also allows expansion at a later stage and therefore flexible planning with fewer module variations. Up to 12 input and output expansion modules each with a width of 22.5 mm can be connected to a controller module. In this way 8 to 96 safe inputs and 4 to 48 safe outputs can be implemented.

The safety control system samosPRO is certified in accordance with EN 61508 to SIL 3, EN 62061 to SIL CL 3 and in accordance with EN ISO 13849-1:2006 up to Performance Level e/category 4. This covers the requirements of mechanical and system engineering applications.

It is mounted on a 35mm profile rail.
