1 Introduction Enabling particularly compact and energy-saving industrial PCs, the Intel® Atom™ processor E6xx series is a very low power system-on-chip (SoC) that offers a new level of platform flexibility. It eliminates manufacturer-specific system busses, such as the front-side bus (FSB), and utilizes the open PCI Express standard for processor-to-chipset interfaces. This feature permits connecting the processor with every PCIe-compatible device, such as I/O hubs from different manufacturers which were developed for application-specific requirements.

The processor is fit for industrial use and it satisfies the requirements for control and automation applications, including those for harsh environmental conditions. No fan is required since the processors in the family consume just 3.3 to 3.7 W due to Thermal Design Power (TDP).

The processor supports Hyper-Threading (HT) which permits the simultaneous execution of two software threads thus mimicking a multi-core processor for the software. At the same time the on-chip power-optimized 2D/3D graphics engine enhances visualization applications at low load on the processor. The processor is suitable for simple control, visualization and communication tasks and it does not only satisfy the requirements of industrial applications but also traffic control, building automation or energy transmission.

This White Paper describes:

• New features of the Intel Atom processor E6xx series

• The application of Intel® Atom™ processors in SIMATIC IPCs

• Application and performance data of the SIMATIC IPCs in an industrial environment

2.1 Intel® Atom™ microarchitecture

Like the long established Intel® Core™ processor family, the Intel® Atom™ microarchitecture is continuously innovated according to a defined schedule. A model is used here designed to deliver ongoing innovation. The Intel processor family follows the "Tick-Tock model" where the release of a new architecture (Tock) is followed by a reduction of the associated processor structures by improving the manufacturing process (Tick). As shown in the figure below, the Nehalem microarchitecture was first produced in 2009 on Intel® 45nm process technology (Tock). In 2010, the same microarchitecture was refined, implemented in the Intel® 32nm process technology (Tick) and released as Westmere.

Figure 2-1

The figure shows Intel's "Tick-Tock model" with the silicon technology of the next generation and with the new processor microarchitecture.

Improvements to the Intel Atom processor family follow a similar predictable schedule, with the difference being that improvements in the microarchitecture and processor manufacture are typically launched at the same time.

In general, the new silicon process technology employs smaller structures (e.g., transistors, conductors) that lower power consumption and power loss (e.g., TDP), thereby reducing the waste heat that must be drawn away from the system.

At the first product launch, the Intel Atom processor E6xx series runs at four different clock speeds ranging between 0.6 GHz and 1.6 GHz. The integrated 32-bit single-channel memory controller supports up to 2 GB of DDR2 memory at 800 MT/s (megatransfers per second). The DRAM configuration is permanently integrated.

2.3 Architecture of the Intel® Atom™ processor E6xx series platform

A major challenge when developing a system-on-chip (SoC) is delivering the right set of features to satisfy a wide range of industrial applications. This is achieved with the Intel Atom processor E6xx series, a highly integrated SoC that connects to application-specific components, i.e. I/O hubs and ASICs, via PCI Express. This approach allows equipment manufacturers to build devices with precisely the features and I/O they need. Intel's solution enables compact designs with the flexibility needed to satisfy the performance, I/O power and board size requirements for space-constrained embedded applications.

Keeping component count low, the Intel Atom processor E6xx series integrates general embedded functionality, such as 2D/3D graphics, display and memory controllers, audio, PCI Express and some basic I/O.

It is possible to achieve a two-chip solution when the other required features can be integrated into an I/O chip. This is illustrated on the right side of Figure 2-2.

Figure 2-2 illustrates that Intel Atom processor E6xx series make manufacturer-specific bus systems superfluous and that they increase the flexibility of the I/O devices.

In comparison: Prior generation Intel Atom processors are paired with an Intel system controller hub using a proprietary front-side bus (left in Figure 2-2). The required system controller hub contains a graphics engine and memory controller which are now integrated in the Intel Atom processor E6xx series. If other I/Os are required, another device, such as an ASIC, can optionally be added.

A drawback of this 2008 platform is that it is not possible to substitute the system controller with a customer-specific device. This restriction is eliminated now with the Intel Atom processor E6xx series. In fact, the new Intel Atom processor based platform accommodates up to four I/O devices over PCI Express. With the 2010 platform, a combination of proprietary devices, such as network adapters, ASICs and I/O hub, can be connected simultaneously, as shown in Figure 2-3.

Figure 2-3 shows that the Intel Atom processor E6xx series connects up to four I/O devices via PCI Express.

Suitable for many industrial applications, the Intel® Platform Controller Hub EG20T integrates a good mix of common I/O. These include SATA, USB client, SD/SDIO/MMC, a gigabit Ethernet MAC, as well as general embedded interfaces such as CAN, IEEE* 1588, SPI, I2C, UART and general purpose I/O (GPIO).

2.4 Technology

2.4.1 Intel® Hyper-Threading Technology

The Intel® Hyper-Threading Technology (Intel® HT Technology) is used in the Intel Atom processor E6xx series. All processors used in the Nano IPCs support this feature which provides the physical processor core with another parallel virtual processor core. Additional program components can be executed in parallel on this virtual core if the processor capacity is not fully utilized by the first thread.

When Intel HT Technology is enabled on the Intel Atom processor E6xx series; the Windows operating system displays two available logical cores in the Windows Task Manager. The performance gain due to Intel HT Technology can be as high as 30 percent, but it depends on the application software. Generally, the performance of a core with enabled Intel HT Technology is lower than the performance of two physically separated cores. Additionally, the overall performance depends on factors such as the degree of parallelization of the programs being processed, dependencies of individual threads on one another, total number of open (running) programs and the distribution of threads by the operating system.

Intel HT Technology provides separate data paths for two tasks which means that the processor maintains two execution states at the same time. As a result, the CPU will process another task if the task it is executing stalls (e.g., waiting for an I/O device), which eliminates wasteful idle time.

The performance improvement derived from Intel HT Technology is illustrated in Figure 2-4, showing three multi-tasking examples. Firstly, the tasks are executed sequentially, task 1 followed by task 2. Secondly, the tasks are assigned alternating time slots. These first two examples require about the same amount of time because they both incur significant delays when the CPU must wait for data. Thirdly, Intel HT Technology executes tasks concurrently, taking advantage of idle time to work on another task and thus reducing overall execution time. The key benefits of Intel HT Technology are greater performance, lower power consumption and smaller form factor, compared to adding a physical processor core to increase computer capacity.

2.4.2 "ACPI" power management

ACPI (Advanced Configuration and Power Interface)

ACPI makes available diverse interfaces - among others, those for power management. There are many options for saving power through ACPI. The computer can assume various "idle states" for this purpose. These "idle states" are defined in the ACPI specification.

Operating modes of the processor

ACPI defines 4 CPU states from "C0 - processor executes code" to "C3 - processor is totally idle". With ascending state number the time increases until the CPU returns to the C0 state.

Operating modes of the system

ACPI defines 5 operating modes from S1 to S5. Some features are given in the following.

Note Availability of the operating modes depends on the installed operating system. Furthermore, note the instructions for the operation of WinAC RTX. (WinAC RTX does not permit using the "Hibernate mode" of the operating system.)

• S0 - System functions normally.

• S1 - CPU in stop, monitor off. "Wake up" to the "S0 operating state" within few clock cycles.

• S2 - Slightly deeper "sleep mode" than "S1". CPU entirely without power. Wake up time slightly longer than "S1".

• S3 - Standby mode. Most of the mainboard hardware has been switched off; the operating state is saved to a volatile memory. "Wake up time" few seconds.

• S4 - Hibernate mode. The operating state has been saved to a non-volatile memory. Complete boot process of BIOS. The operating system will start as from "S3" then. The hibernate mode is ended by switching the IPC off and on with the main switch.

• S5 - Soft-Off: The operating system is shut down and switches the power supply to the Soft-Off mode. The system can be reactivated with a mechanical push button ("power ON") which is connected to the mainboard or - depending on the model and BIOS setting - via the network interface "Wake on LAN" (WoL).

2.4.3 "SpeedStep" power saving function (EIST)

Intel SpeedStep® Technology

Similar to ACPI, Enhanced Intel SpeedStep® Technology serves for power saving of Intel processors. Enhanced Intel SpeedStep® Technology allows reducing the computer performance/clock rate, for instance, if the CPU load is small.

The reduced clock speed reduces the voltage which, in turn, influences the heat generation of the CPU.

Furthermore, costs can be cut thanks to smaller accumulators or capacitors for uninterrupted power supply (UPS) of IPCs.

2.4.4 Wake on LAN

"Wake on LAN" (WoL) allows "restarting" a computer within a network from a remote computer. For this purpose, a special data package (Magic Packet) is sent to the computer which is to be restarted. The computer which receives the "Magic Packet" must be provided with hardware which supports "Wake on LAN":

The following components of the IPC must support WoL:

• Mainboard

• Network adapter

• Adapter driver

• BIOS (Basic Input/Output System)

The computer can thus be activated even though the operating system has been shut down. The power switch must not be switched off.

2.4.5 Graphics Engine Intel® Graphics Media Accelerator 600

The Intel Atom processor E6xx series has an on-chip 2D/3D graphics engine that performs pixel shading and vertex shading within a single hardware accelerator. The pixel processing is delayed until the pixels shall become visible. This reduces access to the memory and improves the performance.

The graphics engine has various Application Programming Interfaces (APIs), including the following:

• OpenGL*

• ES2.0

• OpenGL 2.1

• OpenVG 1.1

It supports hardware-accelerated HD video decoding and encoding.

Decoding: MPEG2, MPEG4 part 2, H.264, WMV9 and VC1

Encoding: MPEG4 part 2, H.264

The display controller supports LVDS and SDVO displays, 80 MHz and 160 MHz, respectively.

Nanobox IPC227D

The following screen resolutions can be defined via the system for IPC227D:

• 640 x 480

• 800 x 600

• 1024 x 768

• 1280 x 1024

• 1440 x 900

• 1600 x 1200

• 1680 x 1050

• 1920 x 1080

• 1920 x 1200

Nanopanel IPC277D

IPC277D is available with the following screen sizes:

• 7" TFT color display touchscreen - resolution: 800 x 480 pixels

3.3 Control with Nano IPCs

In the industrial environment it is not only the maximal achievable performance that plays a role, it is also a minimum performance that is reliably available to ensure a predictable response of a system.

If the software controller SIMATIC WinAC RTX2010 or the fail-safe version SIMATIC WinAC RTX F is used with a SIMATIC Nano IPC, a system can be realized with which a predictable performance will reliably be available both for SIMATIC WinAC RTX (F) and for the Windows part.

SIMATIC Nano IPCs can be used with the software controller SIMATIC WinAC RTX without any restrictions. The following requirements have to be taken into account though.

• Intel HT Technology: The Intel HT Technology might impair the real-time capability of WinAC RTX, especially, at a high load from Windows programs. In the case of applications with high requirements for real-time, in particular, when using the clock-synchronized mode, it is recommended to deactivate the Intel HT Technology (to be done directly in BIOS).

How many logical processor cores does SIMATIC WinAC RTX use?

Generally, SIMATIC WinAC RTX can run both on IPCs with one processor core and also on multiple-core processors. An IPC with one processor and Hyper-Threading appears like a multi-core processor from the software view (and, thus, from WinAC view).

When Hyper-Threading is activated, one of the two available logical processor cores will be used for SIMATIC WinAC RTX. No other applications will run on this logical core then.

The other logical processor core will be available for other applications, such as HMI, then.

Note When "Hyper-Threading" is deactivated, Windows must be set to a "Single-Core HAL" and, if required, WinAC RTX must be reinstalled. Information on this matter can be found in entry: 29001277

3.4 Visualization with Nano IPCs

The following software products are available for visualization applications with the Nano IPCs:

Configuration software:

• Recommended: SIMATIC WinCC V11 Advanced or SIMATIC WinCC V11 Professional

• SIMATIC WinCC flexible Advanced SP3

Note The configuration software also contains the runtime software for operator control and process monitoring on the Nano IPCs.

Runtime software for operator control and process monitoring on the Nano IPCs

• Recommended: SIMATIC WinCC Runtime Advanced V11

• WinCC flexible 2008 Runtime

Note A runtime file is created through compilation of the project file, e.g. by an IPC227D. The created runtime file can be used with one of the runtime software products specified before for operator control and process monitoring on the Nano IPC227D.

3.5 Configuration of visualization applications for Nano IPCs with the TIA portal

WinCC flexible Advanced can be used for configuring the Nano IPCs (IPC227D or IPC277D) by selecting a PC station (WinCC flexible Runtime) as control panel type.

We recommend using the software SIMATIC WinCC Advanced V11 or WinCC Professional V11.

WinCC Advanced V11 and WinCC Professional V11 provide key benefits here:

• The desired Nano IPC can be selected directly in the hardware catalog and be used via the project manager.

• The "widescreen format" is available.

The configuration view of the TIA portal is shown below.

The figure below shows a performance comparison of different processors, focusing on the Intel Atom processors described in this whitepaper.

Figure 3-3

The performance comparison between the Intel Atom E6xx processor platform and Z530 and N270 shows that there are only slight performance differences. The decisive factor is the different distribution of the power consumption of chipset and CPU and the modified bus system. For more information, please refer to chapter 2.2.

The more even distribution of the power consumption of the Intel Atom E6xx processor platform leads to a better distribution of waste heat. Other advantages include the modified bus system (PCIE replaces the FSB) and improved graphics performance

4 Applications

4.1 Control and visualization

Combination of operator panel and control

The combination of operator panel and control on a Nano IPC provides saving of space and permits use in confined space.

Other benefits of this combination:

• Open PC platform The Nano IPC can be combined with other standard software products, such as an Office environment. Archive data which have been created during runtime, for instance, can be displayed immediately with a spreadsheet application in this way.

• Integration of special tasks The engineering tool SIMATIC WinAC Open Development Kit (ODK) permits the flexible use of all resources of the IPC from the control program via three different interfaces to expand the PLC functionality.

• Automatic project transfer If required, different control projects can be loaded to the software controller WinAC RTX during runtime. Different tasks can be adapted during runtime in this way.

• Saving/archiving current PLC parameters A lot of storage space is available due to the PC environment. Therefore, extensive PLC data can be archived permanently and processed further.

4.2 Communication gateway

Implementation of protocols and physical interfaces

It is frequently required to combine different systems. The compact Nanobox PCs SIMATIC IPC227D are a particularly suitable choice here. They have many different interfaces and permit integrating additional functions.

Table 4-1

Available interfaces Optional functions

• LAN

• PROFINET

• Serial interfaces – RS232 – RS485 – CAN

• as PC expansion card (PCIe), e.g. for PROFIBUS

• Diagnostics / Web server An example application is, for instance, "User-defined Web Sites for HMI Operator Units", to be accessed via the entry ID: "48955975" in the online support.

• Data preprocessing

• Integrating additional I/Os, such as PCIe card for SIMATIC IPC227D.

Examples of monitoring large diesel engines or gear units
