Which controllers can be used to set up a PROFINET field bus in PCS 7?

  • Entry
  • Associated product(s)
To set-up a PROFINET fieldbus in PCS 7, you can use AS 410 modular systems or complementary S7-400 systems. It is advisable to use AS 410 modular systems for new systems.


PROFINET is supported as a fieldbus with PCS 7 V8.0 Upd1 and above. From PCS 7 V8.0 SP1 onward, HART communication via PROFINET is released.
Using SIMATIC PCS 7 V9.0 and a wide range of hardware and software innovations, has significantly extended the functionality of PROFINET in PCS 7. To be able to exploit these innovations to the full, it is advisable to use CPU 410 with firmware V8.2 and PCS 7 V9.0. Only this combination makes available the following PROFINET functions:

  • Redundant PROFINET R1 configurations
  • Configuration in Run in standard systems (CiR)
  • Configuration in Run in H systems (H-CiR)
  • High-precision time stamping (SoE)

Following controllers can be used:

Recommended: AS 410 modular systems
When you use CPU 410 with firmware V8.1 and above, it is only possible to use the two integrated PROFINET interfaces to set up the PROFINET fieldbus. With older firmware versions, it is only possible to use one of the integrated interfaces. 

Complementary S7-400 systems
Apart from this, you can use the CPUs below of the complementary S7-400 systems to set up a PROFINET fieldbus:

  • H-CPU via the integrated PROFINET interface from V6.0.1 onward
  • Standard CPU firmware V5.3.1 and above with CP443-1EX30
  • Standard PN-CPU via the integrated PROFINET interface from firmware V6.0.2 onward

To configure the CPU 410-5H, you need at least SIMATIC PCS 7 V8.0 SP1 and the "HUP CPU 410-5H" hardware upgrade package. "HUP CPU 410-5H" is not part of the SIMATIC PCS 7 V8.0 SP1 installation package; you can download it at entry ID 68627630. Newer PCS 7 versions already contain the hardware upgrade package (HUP). 

Following devices can be used:

The entry below contains an overview of the PROFINET devices that you can use in PCS 7 and the functions that they support: 109747976

Apart from this, please pay attention to the information in the "SIMATIC Process Control System PCS 7 Approved Modules" manual. The tables that it contains list the PROFINET components that are approved for PCS 7 in column "F" (functions) marked with a "P" (the component has been approved for PROFINET). You can find the manual in the following entry: 109748745
