More Information

Overview Manuals Digital I/O Groups Measurement Paths Communication Links Replacement Wiring

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.
Description
Siemens 6AT1131-6DE21-0AB0 is the SIJECT CI16iP control interface that combines a CPU314-2DP controller with the machine I/O needed by a SIJECT 16i injection-molding system. The processor executes the control sequence while the interface board gathers feedback and distributes commands to the connected machine circuits.

Digital connections on 6AT1131-6DE21-0AB0 are organized across grouped connectors for switches, interlocks, valves and auxiliary actuators. The CPU reads those input states into its process image, then the output groups transfer the calculated machine commands through their 24 V paths.

Temperature, position and pressure-related signals reach 6AT1131-6DE21-0AB0 through separate measurement sections: thermocouple channels monitor heating zones, linear-scale inputs track mechanical position, and fast analog inputs acquire the configured 0 to 10 V signals. Analog outputs form a different path for continuous command values rather than discrete switching.

Communication on 6AT1131-6DE21-0AB0 is divided among the operator-panel serial link, MPI, PROFIBUS DP and P-Bus interfaces. Each connector serves a defined peer or subsystem, so the complete CI16iP wiring map and saved SIJECT project must be used when the control interface is replaced.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Which information should be captured before removing 6AT1131-6DE21-0AB0?
Photograph and label every CI16iP connector on 6AT1131-6DE21-0AB0, then preserve the SIJECT project, CPU program and communication parameters.
How are heating-zone signals handled by Siemens 6AT1131-6DE21-0AB0?
Eight thermocouple channels on Siemens 6AT1131-6DE21-0AB0 convert the assigned temperature signals separately from the digital and fast analog paths.
Why must digital output commons be checked on 6AT1131-6DE21-0AB0?
The grouped 24 V outputs of 6AT1131-6DE21-0AB0 depend on their assigned supply and return paths, so a misplaced common can disable or misroute actuator commands.
What connects the operator panel to 6AT1131-6DE21-0AB0?
A dedicated serial interface on 6AT1131-6DE21-0AB0 carries operator-panel command and display data, while MPI and PROFIBUS serve different communication roles.
Can the analog and thermocouple inputs of 6AT1131-6DE21-0AB0 be wired interchangeably?
No. 6AT1131-6DE21-0AB0 uses separate conversion circuits for thermocouples, linear scales and 0 to 10 V fast analog signals.
Does a CPU314-2DP marking alone identify 6AT1131-6DE21-0AB0?
No. 6AT1131-6DE21-0AB0 is the complete CI16iP control interface, so the integrated CPU marking does not replace the full 6AT order number.
