The OMRON HMC-EF183 is a 128 MB CompactFlash memory card designed to expand storage capacity in OMRON SYSMAC PLC systems. This flash memory module stores user programs, PLC configurations, I/O tables, and logged data, enabling offline program editing and complete CPU Unit backup without a programming device. The card supports ROM operation during PLC startup, file-based I/O memory logging in CSV or TXT format, and data access via a PC memory card adapter. Pre-formatted with FAT16 file system, it accommodates up to 511 files in the root directory and guarantees 100,000 write cycles. The compact form factor (42.8 mm × 36.4 mm × 3.3 mm) consumes approximately 30 mA during PLC operation and weighs 15 g maximum.
