Features:
- The CPU 314C-2DP executes the SIJECT 16i machine-control program.
- Grouped digital and analog interfaces connect machine sensors and actuators.
- The CI16iP Step B execution adds the documented PROFIBUS DP communication path.
Process inputs enter separate digital, temperature, position and fast-analog conversion circuits.
Calculated commands leave through grouped digital outputs or the assigned proportional-control path.
The operator-panel, MPI/RS232, P-Bus and PROFIBUS connectors serve different system partners.
The Siemens 6AT1131-6DF21-0AB0 SIJECT CI16iP Step B Control Interface may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Keeping four sensor paths electrically distinct
- Digital groups: Four connector blocks collect the documented 24 V input channels.
- Temperature path: Eight thermocouple inputs use their own 16-bit conversion circuit.
- Position path: Four linear-scale inputs acquire the assigned displacement feedback.
- Fast analog path: Two 0 to 10 V channels digitize the documented fast sensor signals.
Separating discrete commands from proportional control
- Digital outputs: Five connector groups carry the forty 24 V switching commands.
- Group supplies: Each output bank uses its assigned load supply and return.
- Voltage outputs: Four analog channels provide continuous ±10 V command values.
- Driver boundary: Proportional-valve outputs connect to the documented external or integrated driver path.
Assigning each communication connector to its peer
- OP link: The serial operator-panel interface exchanges display and command data.
- MPI/RS232: The service connector communicates with a PC, PG or supported operator device.
- P-Bus: The extension interface connects the assigned SIJECT peripheral path.
- PROFIBUS DP: The CI16iP-only port exchanges data with configured fieldbus devices.
Relating the STEP 7 project to the MMC and processor memory
- STEP 7 project: Hardware configuration and PLC logic are prepared in the documented engineering system.
- MMC content: The card can store PLC, recipe, menu and customer-picture data.
- Backed-up memory: The loaded processor program depends on the documented battery-backed path.
- Startup mode: The selector position is checked before the CI16iP is powered and placed in operation.
