DVP-ES3 Series Programming Manual Example 1. The PLC is connected to the VFD-S series AC motor drive (RTU modeSM210 is ON; 16-bit mode: SM606 is ON.). The value 16#12, to be written into the device at 16#2000 in the VFD-S series AC motor drive, is written into the device in the PLC first. PLC VFD-S The PLC sends 01 06 2000 0012 02 07. The PLC sends the data as the following table shown. _6 CRC CHK (01) above is the error checking code. You can calculate it with the CRC instruction (8-bit mode: SM606 is ON).
