CPU 1215C DC/DC/DC for extended-temperature panels
This Siemens S7-1200 CPU 1215C, order code 6AG1215-1BG40-2XB0, runs on a 24 VDC supply rated 20.4 to 28.8 V and operates across -40 to 70 °C. Per the datasheet, the PROFINET interface supports shared-device configuration, and PROFIBUS connectivity is available via the CM 1243-5 module. The unit includes FBD, LAD, and SCL programming and a 4 Mbyte load memory for code and data.
Mounting and integration
Dimensions: 130 mm × 100 mm × 75 mm. PROFINET interface supports autocrossing.
Fieldbus and I/O capabilities
The onboard PROFINET interface can act as client or server and supports shared device and RT/IRT communication. UDP is supported. MODBUS TCP is also supported. Digital I/O forcing is possible. The CPU provides a PID controller function. For analog inputs, the unit accepts 0–10 V and 0–20 mA signals. The backup time for the real-time clock is typically 480 hours. Storage temperature range (-40 to 70 °C) exceeds the operating range, which governs handling after installation.
