Features:
- The CPU divides integrated work memory into independent code and data areas for the S7-400 program.
- Two onboard PROFIBUS-capable interfaces and one IF 964-DP option position organize distributed communication.
- Central-rack, expansion-rack, and multicomputing functions define how the processor participates in a larger S7-400 station.
Siemens 6ES7416-3XL04-0AB0 is the CPU 416-3 configuration for executing control logic and managing I/O in a SIMATIC S7-400 station.
Its memory organization separates executable code from process data and permits load-memory expansion through an S7-400 memory card.
Interface roles, rack limits, and connection resources determine how the processor exchanges data with programming devices, operator stations, and distributed I/O.
The Siemens 6ES7416-3XL04-0AB0 SIMATIC S7-400 CPU 416-3 Central Processing Unit may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

How Program and Data Areas Are Separated
- Integrated work memory is divided equally between executable code and runtime data.
- Load memory begins with internal RAM and can be expanded by an approved S7-400 memory card.
- Data-block count and block-size boundaries shape how the STEP 7 project is partitioned.
Station Structure Around the CPU
- The processor occupies two slots in the central S7-400 rack.
- Expansion-rack support extends the station through the documented S7-400 interface-module architecture.
- Multicomputing allows several CPUs to share one central rack when the station is configured for that mode.
Three Communication Positions with Different Jobs
- The first isolated RS485 interface can operate as MPI or as a PROFIBUS DP master/slave connection.
- The second integrated interface provides another PROFIBUS DP master/slave path for distributed stations.
- The third position accepts an IF 964-DP module instead of duplicating either onboard connector.
CPU Functions Used for Event Timing
- The hardware clock supplies the system time used by program and diagnostic functions.
- Runtime meters accumulate configured operating intervals independently of standard timers.
- Timer and counter resources are assigned by the user program within their documented CPU ranges.
