Features:
- Program and data each receive 5.6 MB within the CPU's 11.2 MB work memory.
- MPI/DP and switched PROFINET are integrated as separate communication paths.
- A plug-in IF 964-DP can add a third isolated PROFIBUS relationship.
Siemens 6ES7416-3ER05-0AB0 executes the S7-400 application while coordinating fieldbus and Ethernet data through distinct interfaces.
Its memory layout separates active program and process data from the card-based load-memory store.
The optional interface position lets 6ES7416-3ER05-0AB0 add another DP segment without converting either integrated PROFINET port.
The Siemens 6ES7416-3ER05-0AB0 CPU 416-3 PN/DP may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Active memory and card storage follow different paths
- Program area: 5.6 MB of work memory holds executable control code.
- Data area: A separate 5.6 MB region holds the active process and block data.
- Load store: FLASH or RAM cards extend load memory without enlarging either work-memory region.
- Backup behavior: Battery backup retains all work memory and an installed RAM card; FLASH does not depend on that retention path.
Three interface positions create separate network roles
- MPI/DP interface: The first RS485 port supports programming, operator, S7, and PROFIBUS relationships.
- PROFINET switch: Two RJ45 ports belong to one integrated Ethernet interface and forward network traffic through the CPU.
- Optional DP path: IF 964-DP adds another PROFIBUS master or device segment at the third interface position.
- Routing: Projected S7 routing connects supported engineering and communication paths across the assigned interfaces.
How the integrated Ethernet path manages distributed IO
- Controller role: The PROFINET interface operates as an IO controller rather than an IO device.
- Device set: As many as 256 PROFINET IO devices can be projected within the documented address and timing limits.
- Startup handling: Prioritized startup and device activation or deactivation are supported for configured IO devices.
- Replacement function: Device replacement without removable media applies to supported PROFINET IO devices managed by the controller.
CPU hardware, software, and rack resources must agree
- Rack space: The processor occupies two S7-400 slots and receives supply through the backplane.
- Engineering baseline: Firmware V5.3 is paired with STEP 7 V5.4 SP5 or a supported later release.
- Optional hardware: The IF 964-DP must appear in the hardware configuration before its third-interface resources are available.
- Diagnostics: The CPU diagnostic buffer can retain up to 3,200 entries for projected and runtime events.
