More Information

Overview Manuals Control Role Network Links Engineering Performance

Features:

  • This CPU runs SIMATIC S7-1500 automation logic with separate PROFINET and PROFIBUS connections.
  • The controller provides 1 MB program work memory and 5 MB data work memory for the station project.
  • A SIMATIC Memory Card is required for operating the CPU and retaining its project data.
The control task combines program processing with distinct network roles: one PROFINET IRT path, one PROFINET RT path, and one RS485 PROFIBUS interface.

Its program and data work memories serve different project contents, while the Memory Card provides the required operating medium for the installed CPU.

Before commissioning, the station engineer should preserve the configured network assignment and confirm that the selected TIA Portal version matches the documented engineering requirement.

The Siemens 6ES7516-3AN01-0AB0 CPU 1516-3 PN/DP Central Processing Unit may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Controller Role

  • Program execution: The CPU runs the user program for the SIMATIC S7-1500 station.
  • Working memory: Program and data areas are separated into 1 MB and 5 MB capacities.
  • Memory card: A SIMATIC Memory Card is required for operation and project storage.
  • Processing task: The stated 10 ns bit-operation performance applies to the controller processing function.

Interface Roles

  • PROFINET IRT: The first PROFINET interface provides a two-port switched connection for IRT communication.
  • PROFINET RT: A second PROFINET interface serves the separate RT communication path.
  • PROFIBUS: One RS485 interface provides the PROFIBUS connection at the CPU.
  • Planning boundary: The three interfaces must be matched to the existing station network design.

Project Preparation

  • Engineering software: Configure the CPU with STEP 7 TIA Portal V14 SP1 or V13 SP1 Update 4, or a later supported release.
  • Firmware baseline: Confirm the installed firmware against the documented V2.1 hardware-function status.
  • Project transfer: Retain the project settings for both PROFINET interfaces and the PROFIBUS interface.
  • Replacement check: Match the full CPU order number and interface set before commissioning.

Electrical Operation

  • Supply input: The CPU uses a 24 V DC supply within the documented 19.2 to 28.8 V DC range.
  • Current demand: Rated current consumption is 0.85 A for the complete CPU.
  • Backplane feed: The unit supplies 12 W to the backplane bus.
  • Heat allowance: Typical power loss is specified as 7 W for cabinet thermal planning.
Description
Siemens 6ES7516-3AN01-0AB0 is a SIMATIC S7-1500 CPU 1516-3 PN/DP central processing unit that runs the controller program and coordinates an automation station through integrated PROFINET and PROFIBUS communication.

A SIMATIC Memory Card is required by 6ES7516-3AN01-0AB0; the CPU provides 1 MB work memory for the program and 5 MB for data, while its stated bit-processing performance is 10 ns.

For network layout, 6ES7516-3AN01-0AB0 provides a first PROFINET IRT interface with a two-port switch, a second PROFINET RT interface, and a PROFIBUS interface, so these three communication paths remain distinct at the CPU.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
How should the two PROFINET paths on Siemens 6ES7516-3AN01-0AB0 be assigned?
Siemens 6ES7516-3AN01-0AB0 has a two-port IRT interface and a separate RT interface, so the network design should keep their required roles and device counts separate.
What memory must be planned for a Siemens 6ES7516-3AN01-0AB0 controller project?
Siemens 6ES7516-3AN01-0AB0 provides 1 MB program work memory and 5 MB data work memory, and it requires a SIMATIC Memory Card.
Can Siemens 6ES7516-3AN01-0AB0 connect to both PROFINET and PROFIBUS equipment?
Yes. Siemens 6ES7516-3AN01-0AB0 includes two PROFINET interfaces and one PROFIBUS interface, allowing those documented communication paths in the same CPU.
Which engineering version is required before configuring Siemens 6ES7516-3AN01-0AB0?
Siemens 6ES7516-3AN01-0AB0 is configurable in STEP 7 TIA Portal V14 SP1 or V13 SP1 Update 4 and later stated versions.
Why does the exact suffix matter when replacing Siemens 6ES7516-3AN01-0AB0?
The exact Siemens 6ES7516-3AN01-0AB0 suffix fixes the CPU memory, interface arrangement, hardware functional status, and firmware details that must match the station configuration.
