Mid-Range Transistor Output CPU for S7-200 SMART:Model ST30, a 24 V DC PNP transistor-output CPU in the SIMATIC S7-200 SMART series—ideal for medium-complexity automation applications requiring balanced I/O count and fast response, such as small production lines, feeders, and inspection systems.
Supports High-Speed Pulse Output (PTO/PWM):Up to 6 high-speed outputs support PTO (Pulse Train Output) and PWM (Pulse Width Modulation).Maximum frequency up to 100 kHz—can directly drive stepper or servo drives for precise positioning and speed control.
Dual Communication Interfaces for Flexibility:Features 1 built-in RS485 port + 1 Signal Board (SB) slot (supports RS232/RS485).Supports MODBUS RTU (master/slave mode)—enables connection to HMIs, drives, and instruments.SB allows adding communication without using expansion module slots.
Built-in Real-Time Clock (RTC):Integrated RTC supports time-stamping, scheduled operations, and data logging.Clock maintained via supercapacitor or battery card—ensures time continuity during power loss.
Seamless Integration with STEP 7-Micro/WIN SMART:Programmed and monitored using STEP 7-Micro/WIN SMART software—supports LAD, FBD, and STL—user-friendly and efficient for engineering.
