Hello, There is a point to be shared regarding your question as continuation to the following discussion:
When a CPU is in STOP mode (for example in S7-300/400), program execution is stopped and LED evaluation program is not working and perhaps data retain their last valid data.CPU in STOP mode means a plant shut-down, you should check LED status visually plus data in diagnostic buffer to find out the reason for fault.
I also suggest reading the following LINKs for introduction of a product with more options to offer: How do you run diagnostics on a WinCC Operator Station for all the S7-400 CPUs connected? S7 300 / S7 400 CPU DiagnosticsI hope these comments help you Hamid Hosseini |

Hello again, Try with SZL ID:=W#16#0119 with one of the following index numbers.In case of "-32638 (W#16#8082)" error try again with SZL ID:=W#16#0174.Please note there is no case of index number 0 as you have tried. Also provide sufficient space for result stored in DR.
Find more information in this manual ( System Software for S7-300/400 System and Standard Functions).
