Introduction
All Maple Systems HMIs programmed with EBPro (EasyBuilder Pro), including every cMT X Series and cMT Series model, are compatible with a Mitsubishi Q00U/Q01U/Q02U/QnUD/QnUDH. Configure your Controller and HMI/cMT with the following parameters to establish reliable communication.
Supported Series: Mitsubishi Q00U, Q01U, Q02U, Q03UD, Q04UDH, Q06UDH, Q10UDH, Q13UDH, Q20UDH, Q26UDH, Q00UJ CPU.

NOTE: EBPro (EasyBuilder) does not support Mitsubishi Q02U CPU for online simulation on PC. When using the Q02U driver, the HMI needs 10 seconds to initiate the PLC Q02U driver. Before initiation is complete, it is recommended not to write data to PLC — this could cause “PLC no response.” Incorrect wiring or data could cause the PLC to be locked. If the PLC is locked, please restart the PLC or reinstall the PLC module.
