The Siemens 6AG1416-3ES07-7AB0 is a SIPLUS S7-400 CPU that runs CFC, FBD, LAD, SCL, STL, and GRAPH programming with isochronous real-time (IRT) over PROFINET. The number of function modules (FM) you can add is limited by the available slots and connection capacity, so block allocation needs to be planned before commissioning.
Connectivity and fieldbus
Integrated PROFINET interface handles UDP and TCP/IP communication via loadable function blocks; a serial port is available for legacy fieldbuses. MPI is not supported—any MPI-dependent network will need a different CPU or a gateway.
Environmental and mechanical fit
Width 50 mm, height 290 mm, depth 219 mm. Ambient -25 to 70 °C, CE marked.
Diagnostics and forcing
Forcing is permitted. Read/write and diagnostic system functions (SFC 51, 58, 59, 13, 55, 103) have per‑interface call limits—for example RDREC and WRREC each allow 8 calls per interface, with a system cap of 32 across all external interfaces.
