Technical support / Online Ladder Logic Program.
« on: March 20, 2007, 09:39:39 AM »
Hello.  Is it possible to access the local PC com ports with the online Ladder Logic emulator?  My task requires polling some equiptment and I would like to be able to test it before buying your super PLC product.  If the local com ports could emulate the PLC's ports that would be great.

Technical support / stumped with duplicate coils
« on: March 16, 2007, 04:16:58 PM »
I am having trouble figuring out how to avoid having dupicate coils in my project.  I have done a few simple projects before with ladder logic but this has me stumped.  The application is basically a washing machine, so I need to turn the coils ( recirculation pump, valves, drain) on and off for different cycle time lengths.  Duplicating the coils looked good until I tried to compile   :( .  So here is the deal.  I have about 5 cycles of different chemicals that need to enter and exit a tank. Some need to be in for 15 minutes, some really just need seconds after the tank registers full.  Can someone point me towards and example like this? - I've been scratching my noggin for days now.
