ADD7 FEM (AddFEM) — Interface
Siemens · ADD7 FEM (AddFEM) · 6DL3100-8AA
Description
The AddFEM (Add 7 Front End Module) is a rugged field electronics module purpose-built for fast turbine control (gas, steam, industrial, and water turbines), providing a rich mix of analog/digital I/O and speed-sensing inputs directly on a PROFIBUS-DP slave interface. It can be used with SIMATIC S7/PCS 7, SPPA-T3000, or SIMADYN D automation processors, with the controlling logic typically implemented in the host automation processor rather than on the AddFEM itself.
