Hello, this PLC don't have any key lock on the front. Try load the new firmware in the PLC, after that the PLC get default setting for Modbus und Modbus+. Warning! You lost your project.

Looks like 140 CPU 11303 can be programmed with either Concept or ProWORX. If you see the PLC over MB+ network with MBSTAT, but cannot connect to it with Concept then it likely has a ProWORX OS in it. Either connect with ProWORX or re-flash with Concept OS. Check manuals before doing that!
