With Hilscher's CIFX 2-channel cards, users have the option of implementing two independent fieldbus communication ports in just one PCI slot. Especially in compact box PCs from the newest generation, the number of PCI slots is rather limited and a 2-channel card has significant advantages. All of the cards have an extended temperature range up to +70°C as well as reliable address allocation on the PCI bus via a rotary switch. The user can choose from any combination of the leading fieldbus systems PROFIBUS, CANopen and DeviceNet. Due to loadable firmware and software licenses, the same hardware can alternatively be used as double master or as double slave. All 2-channel cards use the same application interface and data is exchanged via Dual-Port Memory or DMA. A complete software package is always included in the scope of delivery.
