Safety Integrated

PROFINET IO also allows safety-related signals (e.g. emergency-stop motor) to be exchanged between the ET 200 distributed IO and a SIMATIC S7-CPU. For some applications, wireless communication (IWLAN) is the more cost-effective solution. In some cases, it is the only option, e.g. for communication between mobile or difficult-to-access areas in an automation system. A new use case describes this solution. To this end STEP 7 code can be downloaded free of charge.

In safety-critical applications, the transfer of safety-related data (e.g. emergency stop signal) to a safety-related (failsafe) evaluation unit (e.g. F-CPU) must be ensured, or you must have some other way of exposing errors in data transfer. The PROFIBUS and PROFINET bus systems ensure reliable data transfer thanks to the PROFIsafe safety profile. The safety function example available for downloading illustrates safety-related bidirectional Master-I-Slave communication via PROFIBUS DP.

The SIRIUS 3RK3 modular safety system is a new safety solution for the evaluation of multiple safety functions. The key component is the central module with eight safety-related inputs, one safety-related relay output and one safety-related electronic output. Expansion modules can be used to freely adapt the number of inputs and outputs to the requirements of the application. A DP interface module communicates with a host PROFIBUS network. Safety functions are parameterized quickly and easily using the MSS ES software, which also facilitates comprehensive diagnostics.

The Control Unit (CU) with PROFINET interface and PROFIsafe profile extends the modular system of the SINAMICS G120 series of frequency converters. This means that the SINAMICS G120 series of converters can also be operated in automation and drives architectures with PROFINET, for which safety requirements exist. In addition, the G120 PM240 FS F power modules up to 132 kW will be available from May 2008.

In addition to the frequency converters of the SIMATIC ET 200pro distributed IO system, a regenerative, failsafe version for PROFIBUS and PROFINET is now also available. The frequency converter has unique safety functions such as "Safe torque off", "Safe Stop 1“ and "Safely limited speed". In addition it has regenerative capability.
