6ES7151-7AA00-0AB0 — IM151-7 CPU interface module

This early IM151-7 CPU combines an ET 200S station interface with local program execution. Size the application from its own memory limits and retain the installed project rather than transferring the specifications of a later CPU.

Pre-order check 01

Installation environment

Check the mounting, connection and operating conditions for this exact configuration before installation.

Secure the controlled process and disconnect station power before removing the CPU.
Verify the DC supply is within 20.4-28.8 V and check polarity at the installed terminals.
Preserve the user project and current configuration before disturbing memory or station hardware.
Restore the ET 200S assembly and check the CPU mode and station diagnostics before enabling operation.

Record the installed arrangement and the final controlled checks in the commissioning file.

Pre-order check 02

Compatibility confirmation

Match the complete item to its field interface, mechanical arrangement and configured system.

CPU generation: Keep the complete early-generation ordering code in the replacement specification.
Application size: Check compiled program and data requirements against the 24 KB working-memory capacity.
Load-memory arrangement: Review the 40 KB RAM load-memory requirement separately from working memory.
Engineering version: Use the programming package applicable to the installed CPU firmware, not a later CPU default.
Electrical fit: Match the station supply, terminal arrangement and mechanical envelope before commissioning.

Check the saved project and the early CPU memory architecture before deciding that a replacement is application-compatible.
