The HMIYCF02ITRB is a Compact Flash memory card from the Schneider Electric Harmony Smart range, providing 2 GB of storage for HMI application files, recipes, and data logs. It is classified as a separate part accessory, not a panel-mount component.
What the 2 GB Rating Means for Fit
2 GB is the formatted capacity of the Compact Flash card. For a Harmony Smart HMI, this determines how much space is available for the runtime application, embedded web pages, alarm logs, and trend data. A typical small-line HMI project with a few dozen screens and moderate logging fits comfortably; a multi-machine cell with extensive historical trending may exceed it. The card plugs into the HMI's internal CF slot — no adapter or external reader is needed for installation.
