Great video, what about if the PLC has a red led turned on in SF and there is no card on the slot, do you think could be possible to get a backup from the plc under the conditions described above? , sorry for the akward question but I am new with Siemens PLCs, thanks for your support

There is a communication problem with S7 319-3pn/dp.inorder to troubleshoot the error do i need the memory card to be inserted in cpu.can i test without memory card or in other words is it possible to communicate the cpu with pc without memory card in it.plz help

[@IGSElectronics]

No you need memory card to be able to communicate and do anything with cpu, as it is it’s storage.
