It runs on 24 VDC at 5 W, carries 16 MB application memory with 128 kB backup, and communicates over Modbus and Uni-TE protocols. Compared to the XBTGT1105, the HMISTO511 uses a smaller 200 x 80 pixel monochrome display, draws 5 W, and provides 16 MB application memory with 128 kB backup.","metaTitle":"Schneider HMISTO511 Harmony STO HMI, 3.4\" monochrome, 200x80","metaDescription":"Schneider HMISTO511 Harmony STO HMI: 3.4\" backlit monochrome STN LCD, 200x80 pixels, 16 MB application memory, 5 W, IP65 front, Modbus/Uni-TE.
