3.1 PLC Connection 3-3
PORT2
Set parameters into the special register “R774, 775”, then set “A5AA” (HEX) into the setting complete register “R767”. When
the set value at R767 is changed to “AAAA” (HEX), it is regarded as normal; if it is changed to “AEAA” (HEX), it is regarded as
erroneous.
Parameter setting register
PORT3
