What will happen when I remove memory card and put in pc to read data? Will PLC go stop? Will pc make memory card not readable by plc? Splitted from Sample program: S7-1200 and DATA LOG. |

Hi, from the S7-1200 System manual (http://support.automation.siemens.com/WW/view/en/36932465): 4.5.4 Program card Using a program card as the load memory for your CPU " WARNING Verify that the CPU is not actively running a process before inserting the memory card. Inserting a memory card will cause the CPU to go to STOP mode, which could affect the operation of an online process or machine."" WARNING If you remove the program card, the CPU loses its external load memory and generates an error. The CPU goes to STOP mode and flashes the error LED." |
