  1. AB PanelView Plus

    Hi All, What is the difference between a PanelView Plus and the PanelView Plus 6..??? Thanks
  2. SLC 5/03 Serial Port

    Hi Ken, Thanks...I kind of thought so too, but I wanted to rule out anything else first. I replaced that 5/03 with another one that I found and it worked Great...!! When I get time I think I will replace that 5/03 with a 5/05 and I think I will need to add a 1761-NET-AIC. Thanks again
  3. SLC 5/03 Serial Port

    Channel 1 is my DH-485 port connected to a 1747-AIC module connecting another rack and a PanelView. Channel 1 is configured for DH-485, Channel 0 is configured for DF1. IF I use my UIC connected to the DH-485 port on the AIC to my laptop I can go online just fine. But I can not connect my laptop serial port to the Channel 0 serial port on the 5/03 using a 1747-CP3 cable. RSLinx just can not see the processor. I have tried auto configure and manually configuring the driver, and it still won't connect.
  4. SLC 5/03 Serial Port

    I meant I have tried both ways..!! I have many SLC 5/02, 503, 5/04 and all work well with laptop and serial port. But this one processor I can not talk to serial port...only DH-485
  5. SLC 5/03 Serial Port

    I have checked all the above AND the JP4 Jumper (Protect Mode) on the processor. I am using a 1747-CP3 cable. My serial port on laptop works fine (tried on other processors and works just fine). I have a AB USB to Serial adapter and RSLinx still does not see this processor. If I use a UIC adapter and plug into DH-485 port it works fine and I can go online.
  6. SLC 5/03 Serial Port

    The 9 pin serial port. If I use the UIC I can connect to the DH-485 But curious why the serial port does not work.
  7. SLC 5/03 Serial Port

    I have a SLC5/03 that they are using the DH485 port to go to an HMI. I try to connect to the serial port and RSLinx does not see it. Is there some things to check to find out the reason this port is not working..?? Thank you
  8. High Speed Door Issue

    Well...This is what I ended up with. Works GREAT..!!! ThanksHSDOOR.RSS
  9. High Speed Door Issue

    Well... I will try that , but that would not drop out the door going down tho, would it..??
  10. High Speed Door Issue

    Hi All.. Happy Thanksgiving..!! I have a MicroLogix 1100 running a High Speed door. The problem is that when I:0/7 (Photo Eye) or I:0/6 (Rev LS) goes true after the door starts down, that it does NOT reverse and go back up. Once it is down and I:0/7 or I:0/6 goes true the door does go up tho. Any advice or edit would be appreciated. Im just not seeing it but Ive been looking at it too long. :) Thanks HSDOOR.RSS
  11. Hi All... I have two ML1400 with each IP addressed differently ( and What do I do in each of the ML1400 programs to turn a bit on/off in one by the other..??? Thanks
  12. Simple Heating Circuit

    Yes, I agree. PID is one way but they can be a lot of trouble (regardless of what some claim). Especially on an Oven where variables can change continuously. Ovens can have their own personality depending on age, insulation, door seals, fan circulation, heating elements, thermocouple type, etc. etc. I have 35 Ovens that had PID controllers (that was always giving trouble) and I took them all out and put a PLC with Feed forward logic. I use a mercury relay and feed forward logic in my PLC and I can hold the temp in a 2000 degree F oven within 5 degrees with no problem and it is easy to maintain and troubleshoot. I use a 3 phase mercury relay for switching the power on and off at the speed you want to ramp up the temp and then hold it there. then ramp it down if required. You will have to play with the ramp speed timing when you get within a few degrees of your set point to prevent overshoot and undershoot to the desired target (set point). There might be other ways also, but the feed forward is simple to program and it works. But, everybody has there own way they are comfortable with.
  13. ML1500 Analog Smoothing

    Just so Im clear on this... FV = FV + C (NV - FV) Where: F V = Filtered Value (F8:0) C V = Constant Value (F8:1) (range 0-.99) The smaller the number the more dampening. N V= New Value (F8:2) F8:0 = (F8:0 + (F8:1 x (F8:2 - F8:0))) F8:2 - F8:0 = F8:3 F8:0 = (F8:0 + (F8:1 x (F8:3))) F8:1 x F8:3 = F8:4 F8:0 = (F8:0 + F8:4) F8:0 + F8:4 = F8:0 Is the FV FIltered Value F8:0 my original non-smoothed signal OR my new smoothed signal..??? Is the NV New Value F8:2 my new smoothed signal OR my original non-smoothed signal..??? When you label it as New I just assumed it is the smoothed value. Thanks for your patience in advance..!! I apologize if Im making this more complicated than it is. I just want to do it right.
  14. ML1500 Analog Smoothing

    Will do. Thanks
  15. ML1500 Analog Smoothing

    Thanks Mickey Just curious...are there are any other methods also..??
