  1. Spot Welding with an ABB IRB 6400

    I have quite a few manuals on CD, got them using bit torrent. Worked with the S4C+ controllers and 64/6600's for about 3 years, very simple to program and maintain. The S4's are a bit primitive when compared to the S4C but a few programming tweaks will fix that. Set up a program to home the robot and reset all the I/O if there isn't one already. That alone will save quite a few headaches.
  2. Excellent! That explains why I couldn't find the scanner configuration file in the PLC. Many thanks for the reply and link. It's just what I needed to continue learning.
  3. Would this program create a .dnt file? I don't have RSNetworx on my laptop so maybe that's a good place to start. Assuming the .dnt file is my configuration, how does the PLC incorporate it into the ladder logic for upload/download?
  4. I'm stuck. I' trying to figure out how you add a device to an existing devicenet network and map the I/O. I'm new to the 5555 series software and hardware but I know how to read a manual. maybe I skipped that page, not sure, but no luck finding it thus far. Most of our devices allow for 32 points per device and we use tags, something else I'm struggling to master. My past experience includes plc5 and 500 series using DH+ and Omron PLC's and networks. Working with devicenet is not new, programming with it is. Thanks.
  5. WinMerge ROCKS!

    Looks a lot like Ultra Edit.

    That looks like a cable we use for our Syron sensors, with the same results; very unreliable.
  7. ABB Flexicells

    We've had them here for over 2 years now; the modular design makes them easy to work on and work with. Adding fixtures, tooling and even robots is fairly simple. The only complaint I have is with the software, it's all sequencers! Talk about a PITA to troubleshoot.... Anyone else out there work exclusively with Flexicells?
  8. Have you ever? Did it work? I'm going to try this in a few hours, will post how it went. Usually one ties the signal wire to a PLC and then uses an output from the same PLC to light the light. I'm not sure why I was asked to do it this way but I'll try anything once.
  9. I don't think I made something clear with regards to the accuracy of this device. If you use a narrow plate to trip the prox as opposed to a wide one, the accuracy will increase. If you use several narrow plates, the accuracy improves that much more. More later..busy.
  10. Stumped

    I can't duplicate it on he bench. It only happens in the field. I still think it's strange to see a voltage there with no wires attached until the output goes true. This might be one for the geniuses at AB. (I realize it's feedback through the triac but from what source?)
  11. Easy enough to do. You'll need to 'beef up' one area of the sprocket with piece of plate steel twice the diameter in length as your prox head. Mount the prox close enough to the sprocket to cause the metal you added to trip the prox with each pass. Now figure out how far the conveyor travels for every one revolution of the sprocket. Write this down, you'll need this later. There a several ways to do this now. First you'll need to determine what standard of measurement your going to use, english or metric. Next, you'll have to decide how accurate you want this device to be, that will determine the measurement units, i.e inches-feet-yards or mm-cm etc. Your accuracy will increase with each sensor plate you add to the sprocket. Will you need to 'calibrate' the conveyor belt to control the point at which it stops? I would suggest another prox and trip bar, only this time, mount the trip bar on the conveyor itself. When this bar is sensed, you'll zero the count. Now for some ladder logic. Try a box instruction or two, they're always fun. Remember to include direction information in your program. If the conveyor moves forward, increment the count. If the conveyor moves backwards, decrement the count. If I have time tomorrow I'll bang out a sample ladder and post it. Have fun!
  12. I'm using the 1762-L24BXB model in conjunction with a fire alarm panel. The output in question is #2. With 24VDC applied to VDC2, outputs 2,3,4,5 and 6 function normally. I'm only using output 2, there are no connections to any other outputs mentioned above. While in operation, if the 24VDC supply wire is removed from VDC2, and the wire is removed from outout #2, 8 VDC remains between VDC2 and common. If the contacts are closed via the software, the voltage goes away, as though an internal cap was discharged. it does not come back until voltage is once again applied to the VDC2 terminal. I removed all the wires from the unit except unit power. The same thing happens when voltage is applied to VDC2, it stays there until the contacts for outputs 2-6 are closed. (when I say contacts I'm referring to the output in the logic) I'm checking the ground right out when I finish typing this and take my break. Anyone else seen this with the micrologix series?
  13. RSLogix 500 warning

    I observed this a few times myself, but wrote it off to long hours and no sleep. Good catch.
  14. OMRON touchscreen

    Yeah that's where it was alright, but I was already using that. The problem was that after I changed it I could not get back online. Eventually I did get back online after changing the node ID but I'm not sure how. I will try to recreate the problem tonight, if time allows, using our training simulator. I put the PS back in and the touchscreen problem did not return. Bad host link port. The last time I worked on this equipment I was led astray into thinking the CPU was in cabinet 1 when in reality the CPU was located in cabinet 2. I'm new in this department, still having to take peoples word for things. Thanks for all your help.
  15. CVM1-can't change the node ID

    When I changed the node ID offline I could no longer connect to the PLC. I switched cables and checked the DS settings. I was talking through the seriel port just fine. My boss wanted to know what kind of problem I was experiencing so I showed him, went offline, changed the node ID to 2 and tried to connect, this time, for whatever reason it worked. I didn't change anything between attempts. We have a trainer rack set up in the shop where we program new CPU's. I'm going to work on recreating the problem tonight and post results here. That was too wierd. Thanks.
