Features:
- CPU314-2DP executes the SIJECT machine-control program.
- Grouped digital I/O connects switches, interlocks, valves and auxiliary actuators.
- Dedicated measurement channels separate temperature, position and fast analog signals.
The control interface combines program execution and machine-signal acquisition in one CI16iP assembly.
Discrete outputs switch 24 V loads, while analog outputs carry continuous command values.
Serial, MPI, PROFIBUS DP and P-Bus ports connect different parts of the control system.
The Siemens 6AT1131-6DE21-0AB0 SIJECT CI16iP Control Interface may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Connecting machine states and actuator commands
- Input groups: Forty digital channels collect switches, interlocks and machine feedback.
- Output groups: Forty digital channels transfer the calculated 24 V control commands.
- Connector map: Each group is assigned to a documented CI16iP machine connector.
- Common paths: Supply and return wiring must remain with the correct output group.
Keeping temperature, position and analog acquisition distinct
- Thermocouples: Eight channels convert heating-zone sensor signals.
- Linear scales: Four inputs acquire the documented position feedback.
- Fast analog inputs: Two channels digitize the configured 0 to 10 V signals.
- Analog outputs: Four channels produce continuous ±10 V control values.
Assigning each interface to its intended connection
- Operator-panel link: The serial interface exchanges display and command data with the SIJECT panel.
- MPI: The programming network supports controller communication and service access.
- PROFIBUS DP: The integrated DP interface exchanges data with configured field devices.
- P-Bus: The dedicated bus path connects its assigned SIJECT subsystem.
Preserving the CI16iP connector and project assignment
- Order suffix: The complete 6DE21-0AB0 execution must match the installed unit.
- Cable labels: Record every machine connector before removing the control interface.
- Project archive: Retain the CPU program, parameter set and communication configuration.
- Startup sequence: Verify supplies and signal groups before enabling machine outputs.
