My respect,
We have a complete Unitronics system (USP-156-B10, EX-RC1, and other expansion devices).
One EX-RC1 wont communicate with PLC, only PWR LED gives a signal, the communication LEDs do not.
Second one is working perfectly.
We want to backup the configuration from EX-RC1 and upload to a new device.
Please help me what are the steps! 🙁
