How Can We Help?
E504 message appears
Question
When I try to write a project to a PLC using the programming software:KPP, the E504 message appears and writing is not possible.
How can I do this?
Answer
We are very sorry, but this is a bug in the programming software: KPP.
(We plan to address this in the next update.)
As a workaround, uncheck all items on the retentive register settings screen and write to the PLC.
Next, reconfigure the retentive register with the settings you want (write to PLC), and then write the project.
