Hi, We experience the same problem with a "6es7954-8lc04-0aa0" 4MB memory card. This memory card is the succesor of the "6es7954-8lc03-0aa0" 4MB memory card. The old version of the card is working perfect. When inserting a new card (before power up), the orange LED starts flashing when the CPU is powered. We have tried several new cards en PLC's (CPU215, CPU214), but the all react the same (flash orange LED). With the old version of the card, we have no problems (luckly we have some on spare). Does anyone has an idea what could be the cause and solution for this issue? Thanks in advance ------------------------------------------------------------------------------------------ |

Have you prepared the memory card for use as a program card, or to expand load memory, or whatever? The card needs to be prepared for the specific use case. F1-Help and the S7-1200 System Manual describe what the memory card is trying to do. If I recall correctly, the new memory card is basically moving the project from the PLC to the memory card. However, you really should read up on the correct ways to use memory cards in the s7-1200 PLCs. There are many posts in the s7-1200 conference about memory cards. Might be worth a search.

Hi, which LED is flashing exactly and are there any other LEDs flashing lighting in which colors (also alternating colors)? Compare that with this table: Status-LEDsIs the LED status not described in the table, create a Support Request. regards sancruz |
