I have one s7 300 cpu , 10 IM 151 module and one hmi, all are in profinet network.

i want to show each IM sf/bf led status on hmi.

how to do this. 

------------------------------------------------------------------------------------------
Split from STATUS OF EACH IM MODULE SHOW ON HMI.

Hello,

I am sure, that is not possible to get state of LED in program for IM. I think, you must develop your own "reading-LED-State-Mechanism" (perhaps with the help of error-ob, diagnostic...).

With S7-1500 there is the LED-FunctionBlock, but only for LED of CPU themselves.

Hi,

using system status data read block i access the cpu sf/bf/run/stop status, but im sf status not Access.

Can any one help, to show sf status of Im-151-3.

Hello bhipune

If you had a S71200 or S71500 then you could use the DisgnosticView Control in HMI to see a diagnostiv view of whole peripherie. But With S7300 it does not work in this detailed sight.

Which HMI do you want to use?

Bye Murof

hi,

try this:

PROFINET IO – Diagnostics Processing in the User Program

hope this helps,

Hi, 

I found this old example Getting the "Status for the CPU LED Indicators", that is point to start. See the Ladder programming examples (LAD).

You can have a closer look at SFC51 if it not exactly what do you need. 

New question published by klllll is split to a separate thread with the subject CM1241 RS422/485 and S7-1214 DC/DC/DC CPU: Want to show the transmit and receiver LED status of Modbus module on SCADA.
