Posted 13 Mar 2018 The plc runs for a minute and then the power turns off while the supply voltage is ok. I was sure that it is for the power circuit problem inside the plc. As I had a spare power circuit of cp1h and I checked it had same voltages output (5vdc, 24vdc & 0), I replaced it. Now I cannot connect it with my laptop to change to run operating mode. Could anyone help me? Share this post Link to post Share on other sites
Posted 13 Mar 2018 Can't really help, never torn them apart and swapped internal parts like that. Not sure they are even 100% compatible between models like that. Share this post Link to post Share on other sites
