Explanation of command
Command 01 (Y, R coil read) send
Example) When the 1 bit of Y17 is readed from the unit No. 17 of the remote unit, and a command to transmit
the readed bit data to the 5th bit of the DT100 in the local unit is sent from the COM1.

Example) When the 64 bits (4 words) of data from Y10 to Y4F is readed from the unit No. 17 of the remote unit,
and a command data to the area starting with DT100 in the local unit is sent from the COM1.
