Example
1. The PLC is connected to the VFD-S series AC motor drive (ASCII modeSM210 is OFF; 8-bit mode: SM606 is ON.).
The PLC sends the command, and reads the data in the six devices at the addresses starting from 16#2101 in the
VFD-S series AC motor drive.
PLCVFD-S
The PLC sends "：01 03 2101 0006 D4 CR LF".
The PLC sends the data in the following table.
