The 6ES7648‑2AJ60‑1MA0 is the ECC variant of the 4 GB DDR3‑1600 DIMM for SIMATIC IPCs. Error‑correcting code (ECC) memory detects and corrects single‑bit errors in real time, preventing data corruption that could crash a long‑running process or silently alter critical control parameters. It is the right choice for IPCs running databases, redundant SCADA nodes, or any application where data integrity is non‑negotiable.

ECC for Data Integrity

• Unbuffered ECC: each 64‑bit data word carries an 8‑bit ECC checksum. The memory controller can correct single‑bit errors and detect multi‑bit errors, dramatically reducing the risk of undetected data corruption.
• Industrial qualification: tested for 24/7 operation in the same vibration, temperature, and electrical‑noise environments as the corresponding IPCs.

Compatibility and Installation

• Designed for SIMATIC IPCs that support ECC memory: refer to the specific IPC model documentation to confirm ECC support.
• Plug‑in installation: snap the DIMM into the 240‑pin slot — no BIOS configuration required beyond verifying ECC is enabled.
• Do not mix with non‑ECC modules: ECC and non‑ECC DIMMs must not be mixed on the same platform.
