I have a question, is there a Slimline with AC Input? I am designing a network of 26 machines, where I want to register the time of work, in order to know when it must be make a maintenance, or to to replace some pieces.

As there is too much distance, I think it is good if I assemble this application with a S7-300 PLC with Ethernet Port, and when a machine is started, the PLC begins to count the time; later, this time will be displayed in WinCC.

But I have a little problem. I do not have DC Control in the machines, then I want to know if there is a Slimline Slave with AC Input, instead with PNP Input. Thank you for your help.

Kind Regards,

Mauricio.
