WD: Data area write command

MD: Monitor data save and save reset command

MG: Monitor execute command

RT: Status read command

*We recommend the SI-35 of Lineeye Co., Ltd., for the RS485 converter on the PC side. (When using SI-35, FP2-CB485 (for FP2-MCU), FPΣ (COM3 and COM4) or FP-e, the maximum number you can connect is 99. When using with devices other than these, the maximum number will be limited to 31.)
