Your devices can talk to each other only if they are in the same subnet.
It was suggested to you to change the IP address of your Click PLC to 192.168.2 range.
Have you tried doing so?
Also, look at your reply posted previously:
pi@raspberrypi:~ $ hostname -I
169.254.189.229 192.168.2.16
If these addresses reflect 2 different interfaces, like wired and wireless, then change the IP address of your Click PLC to 192.168.2 range and connect it to the interface that has that
192.168.2.16 address.
