Overview

Product overview

Key product information and technical features.

NI identifies the PC-STEP-2CX among its historical motion controllers. The supplied catalog record places it in the ValueMotion stepper-board range, which NI documents separately from its later FlexMotion and NI-Motion controller generations.

For system maintenance, distinguish this exact PC-STEP model from similarly named PCI-STEP and PXI controllers. Check the physical board identification, host interface, wiring documentation, and installed driver environment before selecting supporting hardware or software.

PC-STEP motion-controller model explicitly listed in NI's historical controller documentation.
Part of the legacy ValueMotion stepper-control product context.
Uses a historical motion-control software ecosystem that must be distinguished from later NI-Motion installations.

Driver distinction

NI-Motion 6.0 does not include ValueMotion; its readme identifies ValueMotion as a separate software package.

Do not select a PXI chassis or PCI host slot from the related-product platform hints; this model's interface still requires model-specific verification.

FAQ

Product-specific questions

Product-specific answers based on available technical information.

Is PC-STEP-2CX the same model as PCI-STEP-2CX?

No. NI lists PC-Step-2CX and PCI-Step-2CX separately. Preserve the complete model designation when checking documentation or identifying a board.

Does installing NI-Motion 6.0 also install ValueMotion?

No. NI's NI-Motion 6.0 readme explicitly states that ValueMotion is not included. Verify the separate ValueMotion software requirements for the existing system.
