I have a Koyo Click. I have a software application that I talk to it with. The Modbus communication is working fine....except......
The Koyo Click has an option to password protect the PLC program. You can't upload/download without the password.
I want my project password protected. I don't want somebody else reading the PLC Program.
The problem is that when the password protection is enabled, the Modbus no longer functions. In order to get Modbus to work, I need to open up the Click Programming software, connect to the PLC, and enter the password. Then the Modbus works fine.
Is there anyway to get the modbus to function while the password protection is enabled? Is Modbus locked or can I use the modbus connection to edit the password?
Any help is appreciated.
