Good day everyone!
I have some question relate with above subject. While i try make protocol for the CJ2M PLC.
i found out "Primary Expression (yN+x)" function but i cannt understand what`s this for. even i tried to find in the reference manual. i can not.
you can find it "Message Editor" -> "Message Variable" -> "Variable"
sorry i tried to upload picture many times but it kept showing failed to upload.
hope so i could find the answer. thank you!
