Detect step7 program detection

[mario_ingen]

hello, I have a problem to see if I can help. I have to follow a failure in a machine, plc has two 300 and 400. The machine turns off (stop) and I can not know that the problem is that the amount of data to follow in the time they are off too.
I thought it was read in a manual siemens at some point, that there is a way to put a block on the program in step 7 and run a routine that tells me the input or bit is turned off.
Anyone have experience with this, from now through

Create a variable table.

if you thought but looking at the same time about 300 variables including trademarks and other securities, and that such failure is given once a day, I think the neck and eyes look so much going to leave me sick, heh.
Actually looking for something more technical .... maybe not doing a routine at step 7 and to throw in the plc, and follow the diagnosis with plcwin analizer for example.

any help is appreciated anyway
