SIMATIC DP, electronic module for ET200S, 2 AO U, 15mm width, +/-10V, 13Bit+VZ, 1..5V, 12Bit, cycle time less than 1ms with LED SF (group error) SIMATIC ET 200S is a modular, scalable, decentralized I/O system that is designed especially for installation in small control boxes close to the machine. 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. SIMATIC ET 200S can be expanded with up to 64 I/O modules that can be plugged in in any combination. The system offers an extensive range of modules. Many modules are also available in different versions, which significantly improves scalability in terms of functionality and price. In addition to modules with standard functionality (ST), there are also modules with an extended range of functions and diagnostics (HF High Feature/HS High Speed). The advantage of the ET 200S system is its ease of use, for example the ability to change modules and terminal boxes during operation. The so-called hot swapping significantly increases the availability and productivity of the machine.
