Industrial Applications

The SIJECT CI16iP StepB is optimized for use in injection molding machines,

where precise control of hydraulic or electric drives is critical.

Its compact design and rugged construction make it suitable for harsh industrial environments.

Troubleshooting and Support

Common issues include:

Connection Errors: During program upload, users may receive errors like “CPU type unknown” (e.g., error

code 6FC5314-6CF00-0AB0).

This typically indicates a mismatch between the controller hardware and the STEP 7 configuration.

Firmware Updates: Siemens recommends using compatible firmware versions to avoid communication

failures.

Technical Specifications

Conclusion

The Siemens SIJECT CI16iP StepB 6AT1131-6DF21-0AB0 is a reliable and compact control solution for

industrial automation,

particularly in injection molding machinery. Its integration with STEP 7 programming software and

support for modular I/O expansion make it a versatile choice for OEMs and system integrators.

However, users must ensure firmware compatibility and proper hardware configuration to avoid common

issues during setup and operation.

For further technical support, Siemens provides documentation

 (e.g., operation manuals 6AT1931-5AB41-0KA0 and installation guides 6AT1931-5AB61-0KA0)

and online resources through its Industry Support portal.

The Siemens SIJECT CI16iP StepB with order number 6AT1131-6DF21-0AB0 is a compact control system

designed for industrial automation applications, particularly in specialized machinery such as injection

molding machines.

This controller integrates advanced features to ensure reliable operation, precise control, and seamless

integration with industrial networks.

Key Features

Hardware Configuration

The SIJECT CI16iP StepB is equipped with a built-in CPU 314 core, which provides robust processing

capabilities for real-time control tasks. The controller supports modular I/O expansion,

allowing users to tailor the system to specific application requirements.

Key components include:

Memory Card Slot: Supports MMC storage cards (e.g., 6AT1131-0GA00-0AA0) for program storage and

data logging.

Communication Interfaces: Includes RS232 and MPI ports for connectivity

with programming devices (e.g., PC/MPI adapter 6ES7972-0CA23-0XA0).

Programming and Software Support

The controller is programmed using STEP 7 V5.x (e.g., 6ES7810-4CC05-0YX0),

a legacy but widely used software platform for Siemens PLCs. Key programming considerations include:

GSD File Requirement: Users may encounter challenges if the corresponding GSD file is missing during

hardware configuration in STEP 7.

Firmware Compatibility: The controller supports firmware versions up to V2.8 (older models)

or V3.0 (newer models).

Mismatched firmware versions may lead to connection errors, such as “Online: No other active partner

can be found.”
