The required files and a description of the procedure for a firmware update are available on the Service&Support pages.

The firmware update to FW 2.6 for all affected modules is provided as a collective download under the following entry: (109478459)

Directions on how to implement the firmware update are available under entry ID:77492231
After the firmware update, the user program, the hardware parameter assignments, recipes and archives on the memory card and the data declared to be "retentive" remain stored on the CPU.

Compatibility between CPU firmware and display firmware:
A SIMATIC S7-1500 CPU with a firmware version V2.6 can be operated with a display with a firmware version ≤ V2.5.

Replacement case: 
When a CPU with firmware version ≤ V2.5 is replaced with a CPU with firmware V2.6, the STEP 7 project does not have to be changed. Upgrade of the STEP 7 software is also not required.

Configuration of a CPU with firmware V2.6 in TIA Portal Versions < V15.1: 
CPUs with firmware version V2.6 can also be used with TIA Portal versions < V15.1. The procedure for configuration with TIA Portal Versions in which the current firmware cannot be selected can be found in the following Entry:  109744163

New properties of the CPUs with firmware V2.6:
Configuration in the TIA Portal STEP 7 Professional V15.1 or higher is required to use the new functionalities.

New functions with firmware V2.6 for SIMATIC S7-1500 CPUs and ET 200 CPUs:

In addition to the OPC UA server, an OPC UA client is integrated in the CPU (RT license required) and offers the following functions via corresponding OPC UA communication instructions:

    • Method calls

    • Reading and writing data

      This enables vertical communication to MES systems/cloud services or controller-controller communication, for example, to be realized.

New features with firmware V2.6 for S7-1500 CPUs (not S7-1500C, S7-1500R/H):

  • Isochronous mode can also be configured for modules that are inserted next to the S7-1500 CPU in a centralized configuration. This means that functions such as the following can be realized:

    • Dynamic control tasks with constant dead times,

    • Precise measuring inputs,

    • Exact cams,

    • Dosing procedures,

    • High-speed analog value acquisition with oversampling

    • Motion control with deterministic position detection

New programming features with firmware V2.6:

  • The number of elements (blocks and UDTs) has been increased for CPUs

    • 1516/1516F/1516T/1516TF/1516pro/1516pro F to 8,000

    • 1517/1517F/1517T/1517TF to 12,000

    • 1518/1518F/1518 ODK/1518F ODK/1518 MFP/1518F MFP to 12,000


Security information
In order to protect technical infrastructures, systems, machines and networks against cyber threats, it is necessary to implement – and continuously maintain – a holistic, state-of-the-art IT security concept. Siemens’ products and solutions constitute one element of such a concept. For more information about cyber security, please visit
