Hello, For an automation project i have to be able to receive and send sms messages. Therefor i use a s7-1200 (1212 ac/dc/relay) and the cp 1242-7. The program i wrote didn't work so i decided to look at an example on this website. CEX21-Szenario3_SMS https://support.automation.siemens.com/WW/llisapi.dll?func=cslib.csinfo&objid=34677186&lang=en&cspltfrm=0&cssw=0&csbinh=8 Accidently i download this example program to my cpu. Now i have the following problem: i cannot access the plc anymore through step7, i have following diagnostic lights on the plc: Run/stop : constant orange error: flashing red. I can still find the plc in step7 through "online access". But when i want to perform a reset to factory setting i get error: "the action cannot be performed in the current operating mode of the module" when i try to change the ip i get error: "the function could not be executed" when i try to flash the leds, they DO flash. The general diagnostics gives no values (all empty) What can i do to get my plc back to life? kind regards, |

Hello nicopereel, Have you gone online with S7-1200 CPU with this same laptop / PC already? If so, did you install any new software? I have came across the same issue recently, where we found that some restrictions were applied to that laptop. (typically on ethernet port settings / firewall). We used another laptop, where as we were able to perform all the above said operations using STEP 7 v11 itself. or alternatively you can use S7-1200 tool to change IP address / reset the CPU to factory settings. |
