The Siemens 6GK1561-1AA01 is a CP 5611 A2 communication processor in the form of a 32-bit PCI card, designed to connect a programming device (PG) or PC to PROFIBUS or MPI networks. It enables PC-based engineering, diagnostics, and communication with SIMATIC S7 controllers and other PROFIBUS devices.
This card is a legacy product with significant compatibility limitations: it supports only 32-bit operating systems and is intended for use with SIMATIC NET V8.2 software or older. It does not support Windows 9x, and for modern 64-bit systems (Windows 10/11), the successor 6GK1561-2AA00 (CP 5612) is required .
