What this display module does for a commissioning engineer
The Siemens 6ES7591-1AB10-0AA0 is a spare part display module for SIMATIC S7-1500 CPUs, designed to fit CPUs running firmware version 3.0 or later. It is a 35 mm module — the same width as a standard S7-1500 slice — so it swaps into the existing CPU front slot without re-laying out the panel. When a display fails on a running line, this spare gets the HMI back up without a CPU replacement or firmware upgrade cycle, assuming the CPU already meets the V3.0 floor.
Lifecycle and compliance at a glance
RoHS compliance is confirmed since 19 December 2022, and the REACH candidate list includes lead monoxide (lead oxide) above the 0.1% threshold. Export control classification is AL: N / ECCN: N, so no special licensing is needed for standard international shipments.
