M1353 has to be set On before EASY EASY PLC LINK is enabled. When EASY EASY PLC LINK is
executed, On/Off of M1353 will not affect the execution.
Registers designated in D1480 ~ D1495, D1576~D1591 (starting register for data read from Slave ID#1 ~
16) and D1496 ~ D1511, D1592 ~ D1607 (starting register for data written into Slave ID#1 ~ 16) can only
be register D, and every special D will correspond to one Slave ID#, e.g. D1480 corresponds to ID1,
D1481 to ID2, and so on.
D1480 ~ D1495, D1576 ~ D1591, D1496 ~ D1511 and D1592 ~ D1607 have to be set before EASY EASY
PLC LINK is enabled. In the execution of EASY EASY PLC LINK, you can modify the contents in these
special Ds, but the modified results will take effect in the next EASY EASY PLC LINK polling.
If the ID# designated by D1480 ~ D1495, D1576 ~ D1591, D1496 ~ D1511 and D1592 ~ D1607 is smaller
than 0 or bigger than 9,900, PLC will automatically correct the ID# into 9,900.
If M1353 is not enabled during the execution of EASY PLC LINK, the range for D1434 ~ D1449, D1544 ~
D1559 (number of data read from Slave ID#) and D1450 ~ D1465, D1560 ~ D1575 (numbere of data
written into Slave ID#) will be 0 ~ 16. If the setting in the special D exceeds the range, PLC will correct it to
16. When M1353 is enabled, the range will be 0 ~ 100. If the setting in the special D exceeds the range,
PLC will correct it to 100.
