Модульные системы S7-400 Siemens

Обзор

C надежными и многоцелевыми системами автоматизации AS 410, система управления процессами SIMATIC PCS 7 предлагает экслюзивные системы автоматизации из серии SIMATIC S7-400, которые, вследствие своей гибкости, могут использоваться в различных областях промышленности. В зависимости от требований она может конфигурироваться как:

• Стандартная AS 410S система автоматизации
• Система повышенной надежности AS 410H
• Система противоаварийной защиты и безопасности AS 410F/FH

С высокопроизводительной аппаратной платформой и оптимизированной прошивкой V8.0, инновационный CPU 410-5H перекрывает спектр всех задач, возлагаемых на традиционные системы автоматизации с AS 412 до AS 417. Производительность системы гибко масштабируется путем количества загружаемых SIMATIC PCS 7 процессных объектов (PO). Системная карта расширения доступна для

• 100 PO
• 500 PO
• 1 000 PO
• 1 600 PO
• ≥ 2 000 PO (PO 2k+)

Сокращение типов CPU к единственному CPU предоставляет много преимуществ. Значительно упрощается выбор и конфигурация систем автоматизации, равно как и спектр запасных частей и возможности расширения системы в последующем.

Дизайн

Similar to all SIMATIC PCS 7 automation systems of the S7-400 series, AS 410 automation systems are available as "AS bundles" as follows:

• Individual components bundled per system in one delivery
• Pre-assembled and tested complete systems (no extra charge compared to delivery of individual components)

With a SIMATIC PCS 7 Industry Library Runtime license and a SIMATIC PCS 7 AS Runtime license, the AS bundles are equipped for 100 process objects (PO). Building on this, the number of process objects can be increased with cumulative AS Runtime licenses for 100, 1 000 or 10 000 POs.

The configuration of the AS bundles as well as the Article No.''s can be defined by selecting pre-configured ordering units. System-specific ordering configurations are available in tabular form for this purpose in the sections "Standard automation systems", "Fault-tolerant automation systems" and "Safety-related automation systems".

For interactive configuration of AS bundles, there are also two online configurators available in the Industry Mall:

• SIMATIC PCS 7 AS 410 Single Station configurator
• SIMATIC PCS 7 AS 410 Redundancy Station configurator

CPU, aluminum rack (except UR1), optionally redundant power supply modules, communication modules and sync modules of the SIMATIC PCS 7 AS 410 bundles have an additional coating (conformal coating).

AS 410 bundles for operating temperatures up to 70 °C

The AS 410 bundles are usually designed for operating temperatures up to 60 °C. Additional designs are available for extreme conditions; these are permitted for operating temperatures up to 70 °C. Their components mainly carry the designation "XTR" (extended temperature range) in their names. All components of the "AS 410 bundles for the extended temperature range (XTR)" also have an additional coating (conformal coating).

The Article No.''s of the AS 410 bundles for the extended temperature range (XTR) can be defined in the sections "Standard automation systems", "High availability automation systems" and "Safety-related automation systems" by means of an individual configuration table. The online configurators in the Industry Mall offer an XTR-specific pre-selection.

Flexible and scalable availability

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

For a SIMATIC PCS 7 AS Single Station of the AS 410 type, 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 the standard automation systems as well as the high-availability and safety-related AS 410 automation systems. With 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
• Additional protection of the circuit board with coating (conformal coating)
• 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

For detailed information about CPU 410-5H Process Automation, see "Technical specifications".

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/O can be operated on a PROFIBUS DP interface in the CPU and on additive CP 443-5 Extended (conformal coating) PROFIBUS DP interfaces. You can configure up to 4 individual or redundant CP 443‑5 Extended PROFIBUS DP interfaces (conformal coating) for an automation system using the configurators for SIMATIC PCS 7 automation systems in the Industry Mall as well as in the catalog sections "Standard automation systems", "Fault-tolerant automation systems" and "Safety-related automation systems".

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 ET 200M or ET 200SP I/O stations (see also the "PROFINET" section in the "Communication" chapter). PROFINET IO interfaces made available by additive communication modules of the CP 443-1 type (conformal coating) cannot be used.

Backup batteries

Lithium backup batteries of type AA with 2.3 Ah are used in the power supply modules of all SIMATIC PCS 7 automation systems of the S7‑400 range (AS bundles). Since lithium batteries are easily inflammable, more rigorous transport and storage regulations apply to them.

To avoid subjecting the AS bundles to these more rigorous transport and storage regulations, the backup batteries must be ordered and delivered separately (order no. 6ES7971-0BA00).

The following backup batteries are required depending on the configuration of the AS bundles:

• SIMATIC PCS 7 AS Single Station with
  • 1 power supply module: 2 units
  • 2 redundant power supply modules: 4 units
• SIMATIC PCS 7 AS Redundancy Station with
  • 2 power supply modules: 4 units
  • 2 x 2 redundant power supply modules: 8 units
