Hi all,
IÂ’m having issue on 1756-OB32 where one of the channel (CH14) keep on has 24vdc, causing my solenoid keep on energising without command. ThereÂ’s no indication light on the module, thereÂ’s no command from plc, but the channel output is on (24vdc). If swapped a new DO card, initially everything went well but after few weeks the same things happen again at the same channel.
Can anyone please advise?
Has anyone met the same issue before?
Regards
Sally
