You can modify the settings in D1434 ~ D1449, D1544 ~ D1559, D1450 ~ D1465 and D1560 ~ D1575
during the execution of EASY EASY PLC LINK, but the modified results will take effect in the next EASY
EASY PLC LINK polling.

END
I170
With I170, the processing of data in EASY EASY PLC LINK will not be done at END, but at the enabling of
I170 immediately after the receiving of data is completed
If the reaction speed of the RS-485 IC direction control signal pin of the Slave is slow, it is suggested that
you do not enable I170.
You can set up D1399 (starting Slave ID designated by EASY PLC LINK), and the ID# of the next 15
Slaves have to be in sequence. For example, when D1399 is set as K20, the Master PLC will detect Slave
ID# 20 ~ 35.
c) Example 3: Connection of 1 Master and 2 Slaves by RS-485 and exchange of 16 data between Master and
Slaves through EASY PLC LINK (M1353 = Off, linkage of 16 stations, 16 data read/write mode)
