Siemens 6GK1561-3AA00 Simatic S7 PLC Module Card

Siemens 6GK1561-3AA00 CP 5613 PCI Card is a PROFIBUS DP master interface that installs in a PCI slot on a PC, PG, or industrial IPC to connect to a PROFIBUS DP network. This 32‑bit PCI card (3.3/5 V signaling; 33/66 MHz PCI bus) provides a dedicated PROFIBUS DP interface for open communications with Siemens SIMATIC NET and compatible devices. As a member of the CP 5613 family, it supports DP master data exchange at standard PROFIBUS DP speeds up to 12 Mbit/s and includes a DP‑RAM interface for DP master operations, enabling reliable cyclic and acyclic data transfers between a PC and DP devices. Typical applications include linking an industrial PC or server to PROFIBUS DP devices such as PLCs, remote I/O, and field devices, enabling configuration, monitoring, and data integration within legacy and open automation architectures. The 6GK1561-3AA00 variant is part of Siemens’ SIMATIC NET lineup for PCI-based CP 5613 interfaces, designed to support MPI/DP communication options and integration with older SIMATIC hardware in retrofits or new builds that rely on PROFIBUS networking. This card provides a robust, field‑proven connection that extends PC‑based control systems into Siemens’ PROFIBUS ecosystem, facilitating reliable device communication and data exchange across industrial networks.
