The Siemens Industry Automation Division has expanded its Simatic ET 200 distributed I/O product family with a new generation of devices. The Simatic ET 200SP with IP20 degree of protection supports Profinet, is characterized by a fast cycle time and high system performance and can be integrated into the automation solution via the TIA Portal or Simatic Step 7 engineering tools. The new Simatic ET 200SP distributed I/O is based on a scalable design with variable station set-up options. The basic device can be expanded with up to 64 modules and can thus process 64×16 signals in the maximum configuration which still only requires one meter in the control cabinet. The compact design also means the system is suitable for standard control boxes with a depth of just 80 mm, even observing the standard bending radii. The integrated power module also saves additional space and simplifies load group formation. The Simatic ET 200SP is equipped with two Profinet interfaces and an internal data rate of 100 Mbit/s ensures delivery of a high system performance. The backplane bus is isochronous with Profinet and can thus provide high-precision, virtually jitter-free data transmission. The bus adapter allows the user to freely select the most appropriate Profinet connection technology: RJ45 or FastConnect.
