Profibus PCI Express cards with flexible NOVRAM memory module
29 July 2011
The FC3121 and FC3122 Profibus PC fieldbus cards from Beckhoff have a PCI Express interface, enabling the transmission of larger quantities of data. The new range can be equipped with NOVRAM cards as an option for the fail-safe storage of data. FC312x series cards for Profibus enable connection via the PCI Express interface. In contrast to PCI, PCI Express accommodates a higher quantity of data, so that the complete number of process data defined by the Profibus specification can be exhausted.
Up to 30kB of Profibus input and output data are transmitted per channel. The fieldbus cards can be used as single-channel (FC3131) or dual-channel (FC3122) Profibus masters or slaves. In dual-channel mode, the two channels act independently of each other.
The fieldbus cards can also be equipped with the FC600x NOVRAM cards as an option. The secured data can be transmitted to another fieldbus card with this memory module, thus ensuring high availability of the machine or plant controller. The NOVRAM cards, with memory capacities of 128, 256 or 512 kB, are of the plug-in type and can be retrofitted.
