Dear lidumazie,
A memory reset meansclearing RAM. You can use the MRES switch to reset the CPU and you can do it as well through STEP7. You can read the following in In S7-400H manual
If you would like to do it in SIMATIC Manager, all you have to do is to select the PLC>Diagnostic/setting>Clear/reset. Both methods will not erase the contents of an EPROM and if you were asking how to erase or clear an EPROM, you have to put your flash card in a programming device(SIMATIC PG)and in SIMATIC Managergo File>S7 memory card>delete. Best regards. H-H |
