Typical mixed configuration limits for SIMATIC PCS 7 automation systems, based on the SIMATIC PCS 7 Advanced Process Library (APL)

¹⁾ up to 200 process objects

Note:

The values quoted here are not AS-specific maximum values for the particular item. Instead, they represent a typical distribution of the available total capacity of the AS during mixed operation of all the items of a contiguous block.

The number of process objects is not an absolute value, but depends on the library used as well as on the number and type of blocks used in the application.

Modular automation systems of the S7‑400 range

The rugged automation systems of the S7-400 series are suitable for universal use. They are characterized by high processing and communication performance. The product range offered basically differs in the following features:

AS 410‑5H/AS 410E automation systems
• Preferred systems for new plants with SIMATIC PCS 7
• Suitable for SIMATIC PCS 7 as of V8.0+SP1¹⁾ or as of V9.0 (AS 410E)
• Standard systems, fault-tolerant systems, and safety-related systems are based on the very same CPU
• Performance of the general-purpose CPU 410‑5H is scalable and expandable based on the number of process objects
• Changes in the type of module during operation (TCiR) possible together with the SIMATIC PCS 7 Engineering System V8.1 and higher
• Redundant PROFINET configurations and configuration changes during operation for PROFINET in singular and redundant applications
Complementary S7-400 systems
• Can be used in plants with SIMATIC PCS 7 V8/V7
• As an alternative to AS 410‑5H/AS 410E, primarily in systems with SIMATIC PCS 7 V7
• Scalable based on types of CPU differing in performance

The CPU for all automation systems of the S7‑400 series is already equipped as standard with the PROFIBUS DP fieldbus connection. Depending on the type of CPU, one or two further PROFIBUS DP interfaces are possible directly on the CPU using additive IF 964 DP interface modules. If required, up to 10 PROFIBUS communication modules can be additionally operated on each CPU.

S7-400 automation systems can be integrated via a PROFINET interface into the CPU in PROFINET IO, some types via communication module CP 443-1 as well.

¹⁾ An additional Hardware upgrade package (HUP CPU 410-5H) is required for SIMATIC PCS 7 V8.0+SP1

Embedded automation systems

The embedded automation system SIMATIC PCS 7 AS RTX is a low-priced compact Microbox system with excellent physical properties. It is especially well-suited for plant-level use in the low to medium performance range or as an OEM product, e.g. in Package Units. Depending on the selected product variant, it is possible to connect the process I/O via a routing-capable PROFIBUS DP interface (SIMATIC PCS 7 AS RTX PROFIBUS) or a PROFINET interface (SIMATIC PCS 7 AS RTX PROFINET).
