Program Example 9: COM2 (RS-485), Function Code H0F
1. Function code K15 (H0F): write multiple bits. Up to 64bits can be written.
2. M1143 = OFF, ASCII Mode, M1143 = ON, RTU Mode
3. For ASCII or RTU mode, ELC COM2 stores the data to be sent in D1256~D1295 and the
received data in D1070~D1085.
4. The messages for ELC1 (ELC COM2) and ELC2 (ELC COM1) are shown in the tables below.
