Introduction
All Maple Systems HMIs programmed with EBPro (EasyBuilder Pro), including every cMT X Series and cMT Series model, are compatible with Keyence KV-L20V/700/1000/3000/5000/Nano Series (KV Studio Mode). Configure your Controller and HMI/cMT with the following parameters to establish reliable communication.
Supported series: KV-L20V, 700, 1000, 3000, 5000 series, KV Nano series
