Chapter 4 Relay Ladder Logic Programming 76
Example 1: Data Link Mode 1
Set ① = 1, ② = 5, set ③ as the initiate of I3, the state of actual sending terminal I3~I7 is sent to memory
list; the controller ID = 3, the state of corresponding memory list position W25~W32, and relationship of
sending terminal is as below:
Example 2: Data Link Receive mode 2
Set ① = 2, ② = 5, set ③ as start from M3, set ④ as start from W17, when enabling the Data Link, the
state ‘ON/OFF’ of M3~M7 is controlled by the state of memory list position W17~W21.
