The CIV 521 interface module connects the world of field bus systems to the real time Ethernet VARAN bus comfortably and flexibly. The multi-language device communicates with all current field buses, from CAN to RS232.

The Professional gateway CIV 521 expands a VARAN bus network with numerous standard interface connections. In addition to the integrated VARAN splitter, which allows configuration of linear structures (1x VARAN-In and 1x VARAN-Out), the module has a standard Ethernet interface that can be used for servicing or integration into an office network.

The CIV 521 also acts as a power supply specifications for decentralized C-DIAS module groups.The main task consists of integrating conventional field bus systems into the flexible VARAN bus network. The user has the possibility to unit both worlds. The module has a CAN bus, an RS232 and RS422/485 interface as well as DIAS, C-DIAS and a TTY interfaces. These can be addressed over the isochronous, asynchronous or administration task of the VARAN bus.

SIGMATEK libraries are available for programming the interface connections, which allow the user to apply standard field bus instructions. The commands are converted to the VARAN bus and output to the respective field bus interface connections automatically, allowing completed development work to be reused efficiently.
