Program Example 11: COM2 (RS-485), Function Code H10
1. Function code K16(H10): write multiple words of data. For ELC COM2 ASCII mode, only 8
words can be written.
ASCII Mode when M1143=OFF
RTU Mode when M1143=ON
2. In ASCII mode, store the data that will be written to the drive in ASCII format in 8 continuous
registers started from D50. Received data from the drive will be stored in registers
D1070~D1076.
