Program example 10: COM1 (RS-232) / COM3 (RS-485), Function Code H0F
1. Function code K15 (H0F): write multiple bit devices. Up to 64 bits can be written
2. M1143 = OFF, ASCII mode, M1143 = ON, RTU mode
3. The messages sent between ELC1 (ELC COM3) and ELC2 (ELC COM1) is shown in the
tables below.
Set value: K4Y0=1234H
Device Status Device Status Device Status Device Status
Y0 OFF Y1 OFF Y2 ON Y3 OFF
Y4 ON Y5 ON Y6 OFF Y7 OFF
Y10 OFF Y11 ON Y12 OFF Y13 OFF
Y14 ON Y15 OFF Y16 OFF Y17 OFF

If the ELC uses COM1 for communication, the program below can be usable by
changing:
1. D1109
→
D1036: communication protocol
2. M1136
→
M1138: retain communication setting
3. D1252
→
D1249: Set value for data receiving timeout
4. M1320
→
M1139: ASCII/RTU mode selection
5. M1316
→
M1312: sending request
6. M1318
→
M1314: receiving completed flag
