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.

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.

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.

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?

Looks a lot like Ultra Edit.

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

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?

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.

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.

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?

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?)

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!

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

We have recently experienced a large number of power block failures in our AD controllers. We only turned the power off and back on for maintenance activities and BOOM!, 8 thousand bucks down the tubes. I'm wondering if anyone else has or is experiencing this same problem. If you are we may need to work together to find a solution and push Kawasaki into some kind of action. I'm looking the board over now without a set of prints, so far nothing. I have been performing component level repair for over 20 years now,but without the right equipment like a Huntron Tracker or an o'scope it's not easy. We do have an analog Simpson, so thats a start. I suspect the diode/scr blocks. They have failed at power up in a few other systems I have worked on, and it turned out to be a bad batch! All I have now are a bunch of theories but ya gotta start someplace!! :-p

The Inspiron 2600 laptop from Dell comes with XP pro but does not come with a seriel port. My question is simply this, how do I communicate with Omron C200H/CVM1-CPU11&CPU21 SERIES PLC's without a seriel port? I read somewhere else a USB-seriel converter will not work for this. Our new systems are coming in with CS1G's so they won't be a problem to talk to. I still have my old laptop and from the looks of things I may have to keep it a while. I'm sure the guys at Omron are all over this and probably have a solution for it which I'm not yet aware of. I thought I would post this here because it may affect a lot of us at some point, if your lucky enough to get a new 'puter like myself. :-p

I'm using several of the 620s and having trouble with one, it loses connection to the host randomly. What I saw first was a connection loss whenever an estop condition was initiated, started tracking that through the logic. It was then reported to me that it happened randomly and got me thinking I was barking up the wrong tree. First thing I replaced was the NT-AL001 232-422 interface, nope, replaced the touchscreen itself, nope, finally replaced the PLC CPU and P/S, nope. P/S for the touchscreen was checked and rock steady at 24.02 VDC. Any ideas or suggestions would be appreciated. The only thing I haven't changed is the seriel cable which runs between the adapter and the PLC, it's located in a cable tray in the basement and not subjected to any movement, that's why I haven't changed it. The ends look ok, no damage there. I plan to set up the components I removed on the bench tonight and see how they work together outside the equipment.

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.

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.

CVM1-CPU21-V2 is what I suspect is causing me problems with a touchscreen. Once I replaced it the touchscreen functioned OK but I can't link to it serially. I can see it on the ethernet connection however. What I found was the node ID for the new CPU was still fac set at 0, it needs to be set at 2. If I go offline to change this I can no longer connect through the hostlink port. I know there's a way to do it but can't recall what it is because it has been a while. Can you help? I'll be here another 6 hours tonight, thanks.

PS to the NT-AL001 was OK, changed the PLC rack P/S and CPU, problem cleared. Now I have a new problem, I can't change the CPU node from 0 to 2. I know it can be done and I'll keep after it until I figure it out tonight. My memory isn't what it used to be I suppose, and my notes from CS1G class don't help me either. I ran into the same problem there and Jay showed us Omron noobs the way. More to come.

Yes the software is free as is the training! You heard me right, you can attend the school in Duluth Ga at no charge. We have several DVT systems and we prefer them to the PPT systems for a number of reasons. I can go into those reasons if you wish, but right now I'm kinda busy.

I'm still working on this, the screen stays on as long as there is no estop. Once machine control reset is lost it displays connecting to host until reset is restored. I'm scheduled for the class in November but I hear that class doesn't deal with this model! Ah well, I'll keep after it, and post my findings.

OK, I checked and auto reset is on. When it drops out I get 2 messages, one is 'connecting to host' and the other is 'setting memory'. I have not noticed the comm or power lamp flickering. I'll continue reading the manual and tinkering tonight until 5am, and promise to post results here. I may even break out the o'scope and check the P/S for AC ripple, which is easier than replacing it. I know it's going to be something simple in the end, don't want to overlook anything.

WindowsXP was installed on our maintenance terminals on the shop floor and since that time we cannot use the scroll wheel on the mouse. The scroll wheel works ok in other applications, but not AB Logix. I've switched between the auto scroll and universal scroll selections already. It's not that big of a deal until you have to look at several rungs. The arrow up/down keys work if your in the left side bar. This helps but I think there has to be a way to enable scrolling, I just haven't found it. Any ideas? Thanks.

Just purchased a copy of Omron Motion Control interface software (WS02-MCTC1-EV2 CX-Motion V2.0) but did not receive a manual with it. No problem, I'll just download it, not. It's not on the Omron website and a web search turned up 2 matches in Japanese and one in Italian. Would you happen to have a copy in that magic box of yours Jay? Or you could just post the link and I'll take it from there, either way will work. I would have called our local rep but they don't work nights! :*-( Thanks in advance. (I'm trying to connect to it via our ethernet connection or SYSMAC LINK, I can talk to the PLC all day long but cannot see this device. We were using some old DOS software but decided to upgrade. I guess I was hoping to bounce right online with the new stuff but that's not happening. I've been at it for about 2 hours now and still no go.)
