SIMATIC DP, Power module PM-E for ET 200S, DC 24V with diagnostics. SIMATIC ET 200S is a modular, scalable, decentralized peripheral system designed specifically for installation in small machine-mounted control cabinets. The modules can either be plugged directly into an ET 200S IM with CPU functionality or connected to a central controller via PROFINET or PROFIBUS. The SIMATIC ET 200S can be expanded with up to 64 peripheral modules, which can be combined in any configuration. The system offers a wide range of components. Many modules are also available in different versions, significantly improving scalability in terms of functionality and price. In addition to modules with standard functionality, there are also those with extended features and diagnostics. The advantage of the ET 200S system lies in its ease of use, such as the ability to change modules and terminal boxes while the system is running. The so-called hot swapping significantly increases the availability and productivity of the machine.
