Posted 20 Apr 2022 The inverter i use is ABB ACS580, using the FENA 21 module. If my inverter doesn't accept ZP.OPEN connection, then what should i do? Can you give me some advice? Share this post Link to post Share on other sites
Posted 20 Apr 2022 Contact ABB. ZP.open just opens an ethernet port nothing else. So either your ZP.open instruction is not correct or your ip & port settings are not. If those are correct than There is something wrong at the other side. Share this post Link to post Share on other sites
Posted 20 Apr 2022 (edited) thanks for the suggestion sir. I will try to contact ABB. I've followed the ZP.OPEN instructions step by step. IP on the inverter is also the same. Edited 20 Apr 2022 by Chelz96 Share this post Link to post Share on other sites
