Q : How to Maintain GD28 Communication with a PLC During Inverter Power Loss?
A: When using the GD28 to communicate with a PLC via EIP/EtherCAT/Modbus TCP, what can be done if the inverter loses power but the customer requires communication between the PLC and the GD28 to remain uninterrupted?
The key to maintaining communication is ensuring that the control board remains powered at all times. You can use an external 24V switching power supply to power the GD28 expansion card, thereby keeping the control board powered and maintaining communication with the PLC.
