Platform protects comms between smart factory and the cloud

Thu, Mar 28, 2019

At the Hannover Fair next week, Infineon Technologies will present what it claims is the world’s first Trusted Platform Module (TPM) specifically for industrial applications. The Optiga TPM SLM 9670 protects the integrity and identity of industrial PCs, servers, industrial controllers or edge gateways, explains Infineon. It controls access to sensitive data in key positions in a connected, automated factory as well as at the interface to the cloud.

The TPM protects sensitive data in connected devices and lowers the risk of data and production losses due to cyber attacks. It also shortens time to market and reduces costs, claims Infineon. Using Infineon’s audited and certified TPMs, manufacturers of industrial devices can achieve higher security levels of the IEC 62443 standard and accelerate their certification processes. Infineon says they can also cut costs for maintenance of the devices through secured remote software updates.

The Optiga TPM SLM 9670 meets the TPM 2.0 standard of the Trusted Computing Group and is certified by an independent test lab in accordance with Common Criteria. Service life is 20 years firmware can be updated on the chip to meet long-term security risks that may be encountered in an industrial environment. The Optiga TPM SLM 9670 has an extended temperature range of -40 to +105 degrees C and is qualified according to the industrial JEDEC JESD47 standard.

The Optiga TPM SLM 9670 is manufactured at Infineon’s security-certified facilities in Germany and will be available in large volumes from the second half of 2019.

Infineon offers application-specific solutions for business PCs and routers, connected vehicles, or cloud applications. The Optiga TPM SLM 9670 will be presented for the first time at this year’s Hannover Messe (1 to 4 April). Infineon will run a demonstrator for energy-efficient and secured smart factories at the stand of Amazon Web Services (Hall 6, Stand F46).

Power supplies’ triple isolated outputs suit robotic controllers

Thu, Mar 28, 2019

For factory automation applications, Cosel has unveiled what it believes is the first integrated power solution for robotic controllers. The RBC200F is a 200W, open-frame, configurable AC/DC power supply with triple outputs tailored for robotic controllers and factory automation.

The Cosel RB series offers three configurable isolated outputs, with one having a reinforced isolation to power intelligent gate bipolar transistors (IGBT) or equivalent applications. It is certified to EN62477-1 Over Voltage Category (OVC) III, by reducing the need for an extra isolation transformer when connected to a distribution panel, ensuring that the RBC200F power supply simplifies the design process for systems architects while reducing costs, claims Cosel. The RBC200F is digitally controlled on the input and output stages to reduce energy consumption.

The RBC200F accepts input voltages of 84 to 264V AC and delivers an output power of 207W. It is designed for convection cooling and can be operated from -20 to +70 degrees C at an altitude up to 3000m, or 9000m in the case of storage. The RBC200F can be installed in any orientation and under standard mounting (horizontal orientation); derating starts from 50 degrees C under convection cooling.

To reduce complexity, the RBC200F features three independent outputs. The master output can deliver 24V adjustable 22.8 to 26.4V, or 48V adjustable 45.6 to 52.8V with 144W output power. The second output can host configured modules of 3.3V/5A ; 5V/5A ; 12V/2.5A ; 16.5V/1.9A ; 24V/1.3A ; 48V/0.65A ; ± 12V/0.7A and ±15V/0.7A with a power of 16.5 to 30W depending on the output voltage. The third output can host any of the single output voltage modules in the same power level. For higher voltages, outputs can be connected in series. All output voltages are adjustable via a built-in potentiometer.

The master output DC/DC converter is based on an LLC resonant topology to optimise efficiency when the second and third outputs are using quasi-resonant-flyback topology.

The RBC200F as an input to output isolation of 3000V AC, and an input to ground isolation of 2000V AC. The isolation voltage between the three outputs has been optimised for robotic controllers applications. Isolation between the master output and output two corresponds to a functional isolation of 500V AC when the isolation between the master output, output two and the third output is reinforced to 3000V AC.

Certiﬁed to IEC/EN62477-1 OVC III and complying with EN61558-2-16, the RBC200F can be directly connected to the installation distribution panel, eliminating the need for an additional isolation transformer.

The reinforced isolation of output three is suitable to supply voltages to IGBTs or IPMs, which reduces the number of power supplies required to power robotic controllers and high power modules in factory automation. By integrating a reinforced isolated output, the ‘three in one’ RBC200F has an equivalent footprint 40 per cent lower than conventional solutions, claims Cosel.

The RBC200F has built-in inrush current limitation, over-current, over-voltage, as well as thermal protection.

The RBC200F is certified in accordance to UL62368-1, C-UL (equivalent to CAN/CSA-C22.2 No.62368-1), EN62368-1, EN62477-1 (OVC III) and complies with EN61558-2-16 (OVC III).

The RBC200F has a built-in active input filter, and conducted noise complies with FCC-B, VCCI-B, CISPR11-B, CISPR32-B, EN55011-B, EN55032-B and the harmonic current emission with the IEC61000-3-2 (class A).

In accordance with IEC62368-1, Cosel’s RBC200F has a leakage current of 0.40 to 0.75mA maximum, though for applications requiring lower levels, the option G offers a leakage current of 0.15mA maximum.

The RBC200F measures 101 x 38.3 x 152mm (3.98 x 1.5 x 5.98 inches), or 101 x 38.3 x 164 mm (3.98 x 1.5 x 6.46 inches) if including a terminal block. Weight is 450 grams. An optional chassis with cover is available on request, as well as a vertical mounting terminal block. In the case of harsh or corrosive environments, a conformal coating option is available (Option C).

The RBC200F has a five-year warranty.

RZ/G Linux aims to reduce industrial control certification time

Wed, Mar 27, 2019

With the aim of reducing IEC 62443-4-2 user certification time by up to six months, Renesas Electronics has collaborated with Civil Infrastructure Platform Security Working Group in Linux Foundation to release a security option based on its RZ/G Linux platform.

According to the company, it will reduce the amount of time required for users to obtain certification under IEC 62443-4-2, the international standard for security technologies used to protect industrial control systems from cyber attacks.

Such cyberattacks on industrial control systems’ infrastructure, such as manufacturing plants and power stations are a serious threat which promoted the establishment of the IEC 62443 international security standard covering industrial control system operators, system integrators and equipment suppliers as well as enterprises and organisations involved in industry and public infrastructure. Within the standard, endpoint devices (sensors and programmable logic controllers – or PLCs) must be certified under IEC 62443-4.

To help developers overcome the certification challenges, the Renesas RZ/G Linux Platform security solution, together with the activities in Civil Infrastructure Platform (CIPTM) project, will enable users to reduce the time required for obtaining IEC 62443-4-2 certification by as much as six months.

Within the IEC 62443-4 standard, IEC 62443-4-1 deals with development process compliance and IEC 62443-4-2 deals with the technical compliance of the devices themselves. Renesas is working through the newly established CIP Security Working Group to develop secure open source software (OSS) that complies with IEC 62443-4-2, to establish guidelines for implementing security functions and applications using OSS, and to help create the testing procedures and testing environments necessary for obtaining IEC 62443-4-2 certification.

Renesas supports embedded Linux devices in the industrial field with the RZ/G Linux platform which combines an RZ/G microprocessor and a verified Linux package with long-term support. The security solution will include all the software and documentation necessary for obtaining IEC 62443-4-2 certification, confirms Renesas. It provides an optimal development environment for products employing the RZ/G Linux Platform.

The new IEC 62443-4-2-compliant security solution is scheduled to be available by the end of 2019, starting with the RZ/G2M microprocessor, with solutions for other RZ/G2 MPUs to follow.

Renesas will continue to provide solutions with IEC 62443-4 support while working to advance enhanced endpoint intelligence to develop shared technologies such as security technology and functional safety technology
