Placing a brand new Siemens Memory Card into a powered and running S7-1200 PLC transfers the PLC program from flash PLC memory to the SMC. From that point forward, the memory card is required to be installed for the PLC to go into run mode. If that is your intent, insert that SMC back into the PLC (with it powered off). Power the S7-1200 back up and it should go into run mode. Download the S7-1200 System Manual https://support.industry.siemens.com/cs/document/109814829 Review the section (Ctrl-F search for "Using a memory card") Of the available options, choose the correct one. It should also tell you what to do with the SMC you have now in order to convert it into the correct type of memory card. That manual is extremely valuable when you are first starting out with S7-1200 PLCs. Hopefully you have a Siemens S7-1200 Starter Kit and can work on it from your work area or desk and learn interactively with real hardware.
