This Siemens PLC (programmable logic controller) is the smart choice for controlling and monitoring compact automation tasks. The modular expandable controller features inputs and outputs, as well as various communication options for convenience. It's seamlessly integrated into a common engineering framework to provide constant data management, such as efficient analysis and fast localisation of errors. An easy-to-read display offers plain text information of an error to cut commissioning times and save on production downtime. The unit's diagnostic function means you don't have additional programming work and makes system spanning easy. Ideal applications include temperature, pump and fan control, conveyor technology and packaging machines.

• Modular design makes the controller expandable without changing its physical size
• Fast counting and measuring motion control tasks are possible without the addition of special expansion modules
• Secure communication, thanks to copy and access protection that prevents opening and duplication of blocks without permission

The main advantage of using an analogue device like this one is simplicity. Rather than learning to write a programme, you can physically hook-up other components, such as signal generators.
