I got this working. The following is the program and a screen shot of it. I filled the N7 table with the numbers 20, 40, 60, 80, and 100. With a time base of 0.01 seconds, that gives times between 0.2 and 1 seconds. Values are tested for equality to select a mole: 20 = mole 1, 40 = mole 2,..., 100 = mole 5. Anyways, I have a few questions because I have to write a report and I need to sound like I know what I'm talking about. 1. What's up with the mask on the SQO? I'm not sure what that is/does and what OFFFFh means. 2. What is the R6 (controller) and what is it used for? 3. What should I do to make the mole turn off once hit? I tried putting the "examine open" switch in the middle of rung 4, but it just paused the timer. I added rung 3 to finish the timer, but it didn't help. Any advice? Should I delete rung 3 or the examine open? 4. There are no pauses between moles, but I'm not sure the instructor has ever seen a Wac-O-Mole machine before... and no one else has ever completed a project on this scale for him before. However, do you guys have any easy-to-implement ideas? If not, it probably wont affect my grade anyways. Thanks, Mike WAC.RSS
