That's only the case if the battery is dead. There is an LED on the power supply module that indicates the status of the battery. If it is on the battery needs replacing. You can install a new battery while the unit is powered.
I'm not certain about whether the setup parameter places any limits on simply establishing a connection with the PLC. On your computer running the older version of Proficy, check to make sure your PLC target in the project folder is using the correct COM port. What are you using for a cable between the computer and the PLC? The port on the power supply module is RS485. You'll need a converter to connect your computer's RS232 port.
I don't think they still offer the demo version of Logicmaster.
