Dear Mr. Viral, check the Article no. 1.2 of the manual sent byhdhosseiniin the previous post. It is mentioned there that FC112 ("GetLEDState") calls SFC51 ("RDSYSST") to query the state of an LED for the CPU. Clear that to use SFC51 for this purpose I must have FC112, which is "sinx" not "GetLEDState" Kindly check and tell me about your Simatic Liberary what is there against FC112.

Hello again, fc112 is not a standard function.You can copy it from s7 program provided here: https://support.automation.siemens.com/WW/llisapi.dll/csfetch/23330722/23330722_Getting_LED_Status.zip?func=cslib.csFetch&nodeid=23867977 the .zip file in front of the .pdf file.Download it and check.For more details and a general solution check what you can get from SFC51. UPDTE:Also check what here can suit your case : 34.20 SSL-ID W#16#xy74 - Status of the Module LEDs Best regards Hamid Hosseini |

Hi, Not sure you already solved. I'd like to ask what you try to achieve (Getting LED State) is for Standard CPU or H-CPU ?

Hello@shish, Thanks for reply. Can read out LED states ald? the reason why i asking is i did reading for all 13 LED states for H-CPU by using SFC 51 with own code. and if you are using H-CPU and not solved yet, i can help with some time.

Dearhdhosseini, I have used your sample program that you have sent me, but i am getting the value at RET_VAL is 8085 with SSL_ID w#16#0119 which states that "Due to a problem in the system, information is not currently available" kindly suggest ! Reg, Ashish

Hello, The program was not my sample, it is an example available here and just give you the correct link.About your problem, as far as comments in networks #2 and #3 suggest, CPU first check the SSL 0119 and in case of error switch to SSL 0174.Check the comment and see the RET_VAL in block called in network #3. Best regards Hamid Hosseini |

Dearhdhosseini, I guessed you are the expert and wrote such beautiful program for me. well, coming to the program, in network-2 i am getting RET_VAL 8085 (-32635) and network-3 is not being executed.

Hello again, I have written several codes in STL and SCL here, I never try LAD,You can search for what I have done here.In what CPU are you checking the program?The feedback from the block should be like this: 8082 SSL_ID is wrong or is unknown in the CPU or SFC. (-32638) in your case, I guess you are trying execution on PLCSIM? 8085 Due to a problem in the system, information is not currently available (for example, due to a lack of resources). (-32635) Update for more information Hamid Hosseini |
