When you turn PLC on STOP LED is slowly flashing? If yes - for 90% it's initialization mode. In this mpde it can't be accessed. Wait for 10-15 minutes. CPUs should go into normal STOP mode. Then you can do required operations. You can find out more on https://support.automation.siemens.com/WW/llisapi.dll?func=cslib.csinfo&lang=en&siteid=cseus&aktprim=0&extranet=standard&objid=10805186&DataKey=10805186&treeLang=en |

hi, You can only download to a FLASH Card when the CPU is in Stop. The manual Automation System S7-400 CPU Specifications requires you to stop the CPU by using the mode selector switch. (See chapter 1.5, page 1-19) To be able to download changes in RUN, you need a RAM memory card. hope this helps, regards, |
