Program Example 3:
1. Function code K16(H10): For writing many word data into register.
When PLC is connected to VFD-S AC motor drive: M1143 = Off, in ASCII mode
When PLC is connected to VFD-S AC motor drive: M1143 = On, in RTU mode
2. When in ASCII mode, the user stores the data to be written in the designated register D50 in hex format. The
data sent back from AC motor drive are stored in D1070 ~ D1076.
