Features:
- The CPU combines digital, relay and analog I/O with program execution in one device.
- Two PROFINET ports connect controller, HMI and engineering traffic through an integrated switch.
- Signal boards and expansion modules extend communication and channel capacity around the compact CPU.
Machine signals enter the onboard process image before the user program evaluates them.
Program results drive the relay and analog outputs while diagnostic data remains available to the project.
High-speed counters and communication services operate alongside the cyclic control task.
The Siemens 6ES7215-1BG31-0XB0 S7-1200 CPU 1215C Controller may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Coordinating discrete and analog signals inside one CPU
- Digital inputs: Fourteen 24 V DC points supply machine-state data.
- Relay outputs: Ten contacts switch external load circuits at up to 2 A.
- Analog inputs: Two 0 to 10 V channels measure continuous signals.
- Analog outputs: Two 0 to 20 mA channels send continuous commands.
Sharing two physical ports across one controller interface
- PROFINET: The CPU exchanges cyclic I/O and controller data.
- S7 communication: HMI and peer devices use the configured S7 connections.
- Open Ethernet: TCP/IP, ISO-on-TCP and UDP serve application communication.
- Web server: Browser diagnostics use the enabled CPU web functions.
Keeping program, retained data and added hardware roles distinct
- Work memory: The executing program and active data use 100 KB.
- Load memory: The downloaded project resides in the 4 MB load area.
- Retentive data: Selected values can use 10 KB across power cycles.
- Module capacity: Three communication modules, one signal board and eight signal modules can extend the CPU.
Handling events that cannot wait for the normal cyclic scan
- High-speed counters: Dedicated hardware captures pulses up to the documented frequencies.
- Input filters: Parameter groups balance noise rejection and response time.
- Analog conversion: The two onboard voltage channels update on a 625 µs conversion path.
- Task timing: Counter and analog values enter the program through their assigned process data.
