Introduction
All Maple Systems HMIs programmed with EBPro (EasyBuilder Pro), including every cMT X Series and cMT Series model, are compatible with a Mitsubishi F930GOT Server. Configure your Controller and HMI/cMT with the following parameters to establish reliable communication.
Supported Series: F930GOT general-purpose communication Type 1

Protocol
Read Command
PC to HMI request frame (read RW0, 1 word / 2 bytes). STX = 0x02, '0' = Read command, CR = 0x0D.
PC → HMI
02 '0' [Read address] [Size] CR
02 30 30 30 30 30 30 32 0D
Read address (hexadecimal): 0 ~ FFFF = RW0 ~ 65535
Size (hexadecimal): 2 ~ FE = 2 ~ 254 bytes = 1 ~ 127 words (must be even)Code language: JavaScript (javascript)HMI to PC response frame (RW0 = 0x0010 = 16):
