  1. Well... since you asked. I tried installing the 9.0 software (from CD that came with my 1040) which then UNISTALLED my 8.6 software and will not run. Next I tried reinstalling 8.6 and now I just keep getting the error box that says: 'RUN TIME ERROR 2006- INVALID TOOLS COLLECTION INDEX' and wont let me open ANY of my Visilogic programs..... HELP!
  2. Quick question... How would you enable to a user to enter the value on a timer through the HMI and then have that timer value referenced in the ladder?? I have tried using the "timer" icon on the HMI tool bar which does allow for keypad entry and then lets me reference said timer in the ladder but the value entered on the HMI does not actually appear in the timer on the ladder? What am I missing here? Thanks!
  3. OK great thanks! At least I know what direction to head now. So I have spent all morning reading about PID and I understand the idea but there is still a few concepts I'm not getting... I understand that you must first configure your PID. Question #1: When configuring, how do I know what to put for PROPORTIONAL BAND/INTEGRAL TIME/DERIVITIVE TIME/SAMPLE TIME??? Question #2: I am totally not understanding the AUTO-TUNE concept... So you configure your PID then suspend it so you can run AUTO TUNE then the program is free to run the PID? Is that correct? I apoligize for my ignorance, thanks for helping.
  4. Thanks for the replies! In answer to your question, the program will be running a press. This is a hydraulic ram that is used in a plastics molding factory, the ram is basically similar to a giant bottle jack that presses pellets of nylon into fittings (ie; PVC type fittings). The variables are time and pressure, the user is going to have around 5 "recipes" depending on the material he is using. I need the user to be able to specify something like 2000PSI for 15 seconds... Then I need the program to be able to reference the MI from the pressure transducer and say "hey I'm only at 300PSI" and then pressure up to 2000PSI and count down from 15 seconds...
  5. Hello, I have a problem I can’t figure out with Visilogic. I am trying to create a program in which will be used to control a hydraulic press for a plastics factory. This requires “recipes†that have different times and pressures. I think I have figured out how to enter the recipes but the part I am stuck on is the analog output. I am using an analog signal from a pressure transducer and outputting analog signal to a +/-10V pump control (PSI) (using an IO-AI4-AO2) I can’t figure out how to make the program reference the current system pressure then compare that to the users desired “target†pressure then send the needed output to the +/-10v control. EX: The user requires a pressure of 600PSI and the transducer is reading 50PSI---- The program compares the difference then between desired pressure and actual pressure and analog outputs to the +/-10V pump control. THANKS!!
