Posted 29 Jan 2019 Hello I have a Mitsubishi FX in my production line, but I have a problem, If I lose the electric power I lose the connection between PLC and network, I need to restart the PLC for connection again of PLC in my network. Share this post Link to post Share on other sites
Posted 30 Jan 2019 (edited) Hello Antonio. Can you expand on your problem, what hardware are you using to establish this connection? Ie Ethernet or RS232? If you want communication to your PLC at ALL times; you could consider a UPS or possibly a control circuit powered from your incoming side of the isolator. However for the latter; you will need to check the electrical regs for your respectable country first.

Posted 30 Jan 2019 hi collinsd70 the connection is from ethernet, and yes, I have a UPS in my IDF of communication but the problem happens in the PLC conexion. Share this post Link to post Share on other sites
Posted 30 Jan 2019 Okay, so does the PLC remain on when the power goes out? Is the PLC ethernet passing through a router or switch? Regards Daniel Share this post Link to post Share on other sites
