Product Overview
The CPU 417-4H is a fault-tolerant S7-400H central processing unit with separate code and data memory, MPI/DP and PROFIBUS DP communication, and two dedicated synchronization-module slots.
A matched pair can operate as an S7-400H redundant system with automatic synchronization and redundancy diagnostics. The CPU provides one MPI/DP interface, one PROFIBUS DP interface and two slots reserved for synchronization modules. The H-CPU performs a self-test after power-on and supports the redundancy event organization blocks used by the H system.

Frequently Asked Questions
Which STEP 7 release is required to configure 6ES7417-4HL01-0AB0?
Engineering requires STEP 7 V5.1 or a later compatible release.
How much work memory is available in 6ES7417-4HL01-0AB0?
The CPU provides 4 MB in total, divided equally between code and data.
Can standard DP interface modules be installed in the synchronization slots of 6ES7417-4HL01-0AB0?
Those two slots are reserved exclusively for H-system synchronization modules.
How many DP slaves can the second interface of 6ES7417-4HL01-0AB0 control?
The second PROFIBUS DP interface supports up to 96 slaves.
Does 6ES7417-4HL01-0AB0 perform a self-test after power is applied?
The H-CPU performs a self-test after power-on.
Which redundancy organization blocks are relevant to 6ES7417-4HL01-0AB0?
The controller supports OB70 and OB72 for redundancy events.
What must be aligned when replacing one CPU in a 6ES7417-4HL01-0AB0 redundant pair?
The two sides must use compatible hardware, firmware, synchronization modules and project configuration.
Compatibility & Ordering Notes
Compatibility Checklist
- Use matched and compatible CPUs on both sides of the redundant station.
- Keep the two H-sync module slots free of ordinary DP interface modules.
- Preserve the S7-400H project and synchronization-link configuration before replacement.
