PLCSIM Timing Diagram

[Bret Davis]

I am running a program on STEP 7's PLCSIM, and I want to create a a timing diagram of the I/O as the program runs. Currently to do this I use the Record function of PLCSIM to produce a text file of the cycle time between any inputs and outputs. This though does not indicate which inputs or outputs were triggered and requires me to write out all of the I/O in excel to graph it. This is not the fastest and simplest thing to do so I was wondering if there is any other way to do this?

It may be possible to use OPC to accomplish this.

Quick googling turned up the following:
