Application
Writing the time in RTC in PLC_B directly into D0~D6 of PLC_A without writing in ladder diagram into
PLC_A.
Network
environment
(1) Adopt a static IP address.
(2) IP addres of PLC_A: 192.168.0.4
(3) IP address of PLC_B: 192.168.0.5
(4) Update from PLC_B to PLC_A.
1. See 6.1 for how to set communication.
2. Compile the ladder diagram in the MPU and download it to PLC_B. We do not need to write any corresponding
ladder diagram into PLC_A.

Explanations:
•
The data exchange will be executed every one second.
•
Write “0” into CR#28, and PLC_B will use CR#25~CR#26 as the IP address of the destination PLC.
