  1. ControlLogix DLL File

    Right, but I thought in my past experience we could do something like this with ControlLogix processors as well... neech
  2. ControlLogix DLL File

    @gclshortt That helped somewhat. However, he didn't say what the "special" folder name is. Also, I am trying to do this for a logix controller not SoftLogix. Need to make sure if I include the DLL in the special folder it will download with the program? Thanks, neech
  3. ControlLogix DLL File

    Hello, I've been wracking my brain, but I thought I remembered there was a way to store and execute a DLL file inside of a ControlLogix (not softlogix) controller? You could use exposed functions inside the DLL to fit your needs. Am I going crazy? Or is this not possible? Any insight into this is much appreciated. Thanks, neech
  4. Update: The world makes sense again. Being that this is a sinking device, I needed to measure across power and signal instead of signal and ground. Now, I need to figure out how to wire this up to my plc...maybe I can use an opto-isolator to convert to sourcing? I could maybe rewire the group of inputs as sinking, I will see. Thanks, neech
  5. Update: The sensor I am using is an IP810 hall-effect sensor current sinking pulse.
  6. I have a "paddle wheel" style flow meter that I am trying to wire to my Micrologix 1400. It is a three wire device and there is a tag on it that says it can run at 6-36VDC. So, naturally, I thought to wire this to one of the HSC inputs of the Micrologix directly. I hooked the ( + ) on the meter to 24V, ( - ) on the meter to common, signal to the oscilloscope, and ground on the scope went to common. I see a small 60Hz sine wave @ like 5mv when the wheel is not turning. When the wheel is turning I get a small square wave but in the same mV range. It is not a nice smooth square wave either its all jumbled up with the 60Hz sine wave.  I hooked this thing up to a transmitter and scoped the signal and ( - ) in parallel with the wheel - I get a nice smooth square wave signal when the wheel turns. It is only at 4.5V though. My questions are? Why does't the paddle wheel give me what I am expecting directly? Also, what is the voltage range on the pulse that a micrologix will see? I am assuming that it will not count a wave with a 4.8V amplitude.... Thanks for your help in advanced! neech

    You are right. I tested it and it is working. Thanks again for your help!

  9. RSLogix500 Ladder Problem

    Thanks guys, that worked (almost) perfectly. The only issue is when the last bit goes low, the timer doesn't start. So, when N7:0 and N7:1 both go to zero...maybe I can figure it out from here though. I appreciate your help. HERE IS THE CODE: SOR BST CLR N7:0 NXB CLR N7:1 BND EOR  SOR XIC B3:0/0 OTE N7:0/0 EOR  SOR XIC B3:1/0 OTE N7:0/1 EOR  SOR XIC B3:2/0 OTE N7:0/2 EOR  SOR XIC B3:3/0 OTE N7:0/3 EOR  SOR XIC B3:4/0 OTE N7:0/4 EOR  SOR XIC B3:5/0 OTE N7:0/5 EOR  SOR XIC B3:6/0 OTE N7:1/0 EOR  SOR XIC B3:7/0 OTE N7:1/1 EOR  SOR XIC B3:8/0 OTE N7:1/2 EOR  SOR XIC B3:9/0 OTE N7:1/3 EOR  SOR BST NEQ N7:0 0 NXB NEQ N7:1 0 BND EQU N7:0 N7:2 EQU N7:1 N7:3 TON T4:0 1.0 10 10 EOR  SOR BST MOV N7:0 N7:2 NXB MOV N7:1 N7:3 BND EOR  
  10. RSLogix500 Ladder Problem

    Ok, so I have 22 bits that I need to monitor the status of; all in separate words. Each change of state (on each bit) I need to trigger a timer and have the timer done to completion. I'd like to have the timer reset if a bit changes state during timing. I'd like to keep it to one timer. I'd like to keep things as simple as possible so the less rungs / branches the better. Any help?
