Usage
Essential for engineering stations running STEP 7, WinCC, or MicroWin. It allows the PC to act as a Class 1 or Class 2 Master on the Profibus network. The «A2» revision offers improved compatibility with modern PCI slots.
Legacy Note
As PCs move to PCIe (Express), standard PCI slots are becoming rare. This card is critical for maintaining legacy Industrial PCs (IPC) that control older machines.
