Program Example 9: COM2 (RS-485), Function Code H0F
1.
Function code K15 (H0F): write in multiple bit devices. Up to 64bits can be written.
2.
PLC1 connects to PLC2: (M1143 = OFF, ASCII Mode), (M1143 = ON, RTU Mode)
3.
For ASCII or RTU mode, PLC COM2 stores the data to be sent in D1256~D1295 and the
received data in D1070~D1085.
