Like all SIPLUS PCS 7 automation systems in the S7‑400 series, AS 410 automation systems are only available as individual components:

Flexible and scalable availability

A particular characteristic of the modular S7-400 systems is the flexible and scalable availability of various components.

For a AS 410-type SIPLUS PCS 7 AS Single Station, you have the option of specifically increasing the availability by implementing a redundant configuration of the power supply or the Industrial Ethernet communications module, and combining these measures.

Even the AS Redundancy Station of the AS 410 type with its redundant CPUs offers significantly higher availability. It operates according to the 1oo2 principle, in which a switch is made from the active subsystem to the standby system in the event of a fault. Starting from here, you can double the power supply or the Industrial Ethernet communications module for each subsystem, and combine these measures.

CPU 410-5H Process Automation

CPU 410-5H Process Automation

The CPU 410‑5H Process Automation is at the heart of standard automation systems as well as high-availability AS 410 automation systems. With system expansion cards for 100 PO, 500 PO, 1 000 PO, 1 600 PO and ≥ 2 000 PO (PO 2k+), you can define your performance for your specific application with up to around 2 600 PO.

If the performance limit defined by the system expansion card is reached during configuration, commissioning or operation, a subsequent increase in performance is possible without replacing the hardware by using an appropriate number of CPU 410 Expansion Packs 100 POs/500 POs.

As shown in the figure, CPU 410-5H Process Automation is equipped with two PROFINET IO interfaces (2-port switch in each case) for up to 250 I/O devices and a PROFIBUS DP interface for up to 96 PROFIBUS DP slaves. Two integrated slots allow the synchronization of two redundant subsystems via sync modules and sync cables (FOC).

CPU 410‑5H Process Automation supports NTP as well as S7 time synchronization.

Other features include:

• Integrated 48 MB load memory and 16 MB RAM each for program and data
• Cycle time up to 10 ms/9 process tasks
• Total number of I/Os (on PROFIBUS DP and PROFINET IO) approx. 7 500, 16 KB each for inputs and outputs
• Expanded temperature range during operation up to 70 °C (as of product version 2)
• High-precision time stamping
• Recessed RESET button
• Preset hardware parameters (PCS 7 skinning)
• Changes in the type of module during operation (TCiR) in association with the SIMATIC PCS 7 Engineering System V8.1 and higher

I/O connection via PROFIBUS DP

The distributed process I/O can be integrated into a PROFIBUS DP segment either directly or via a lower-level fieldbus (PROFIBUS PA or FOUNDATION Fieldbus H1). For details on this, see sections "PROFIBUS DP", "PROFIBUS PA" and "FOUNDATION Fieldbus H1" in the "Communication" chapter.

PROFIBUS DP segments with distributed process I/Os can be operated on a PROFIBUS DP interface in the CPU and on additive SIPLUS NET CP 443‑5 Extended PROFIBUS DP interfaces (6AG1443-5DX*). You can configure up to 4 individual or redundant SIPLUS NET CP 443‑5 Extended PROFIBUS DP interfaces (6AG1443-5DX*) for one automation system using the configurators for SIPLUS PCS 7 automation systems in the Industry Mall as well as in the “Standard automation systems” and “High-availability automation systems” catalog sections.

You can additionally implement further PROFIBUS interfaces using separately ordered CP 443-5 Extended PROFIBUS DP interfaces (conformal coating). According to the manual, up to 10 CP 443-5 Extended interfaces (conformal coating) can be operated in one automation system.

I/O connection via PROFINET IO

You can easily and efficiently connect AS 410 automation systems to remote I/O stations via the PROFINET IO interfaces integrated in the CPU 410‑5H Process Automation, for example, to remote SIPLUS ET 200M or SIPLUS ET 200SP I/O stations (see also the "PROFINET" section in the "Communication" chapter). PROFINET IO interfaces provided by additive communication modules of the SIPLUS NET CP 443-1 type (6AG1443-1*) cannot be used.
