yes I did that today as well for the first time. Normally I click View New posts, but I read them all. I've done this for years. But your right, if you don't read them all. View New Posts is tied to your last visit. I can see the sense here. We did not have anything like that before in previous board versions that I recall, I know we do alot of modifications and sometimes we don't get a modification back when we do an major upgrade but I am pretty sure I don't remember a suggestion like this. I think it's valid. I'll have to research and write some code to make it happen and give a choice maybe how you want to view the topics. Chris Elston

hmm..ok let me check into that. I think I see and understand your logic.

So does any one have any idea what market share of installation say Allen Bradley has in the USA market? Or Omron? Or GE? etc?

480 SINGLE phase? Really? not 3 phase?

By chance, would any of you happen to have any good workstations that you are upgrading and want to donate your old work station(s) to a good High School Robotics Team would you? Looking for two good work stations to run AutoCad Inventor and one to run 3Ds Studio Max animation software. They need to be pretty beefy machines especially that 3Ds Max computer. Inventor could be a slower PC. I know it's a long shot, but hey maybe someone is getting an early Christmas present and had some slightly older machines they wouldn't mind letting some kids use for education and learning how to become an engineer.

Mr. Willers, Thank you very much for this direction, the ARC report. That's what I was looking for, where to get the information or what orgainzation has that data. Chris

I like: ABB Mitsubishi

All fixed up.

Thank you Ron for pointing that out. We'll fix it and upload the version 6.0 this weekend.

I dunno if this will help but have you seen my Cognex Article to a Robot? It might show you some stuff in there that might help. http://www.mrplc.com/kb/index.php?article=72

Geez...residential electrical is ROUGH...

Please post in English if you can. Thank you.

Just a quick question. I have a Cat 4 safety installation. I buy a Cat 4 safety relay, hook it up with two-channels, manual reset, e-stop, and connect monitoring etc... But I want to shut down a 3-phase motor.... My external K1 and K2 relays. Do they need to be safety contactors that can handle the amperage of the 3-phase motor (fractional HP) or can I use a standard motor contactor with a N/C contact to monitor back to the safety relay? The safety relay channel one connected to K1 and channel two connected to K2 will control the coils of external K1 and K2 contactors, in this case which are in series to a 3-phase motor.

It seems I stumbled upon a product "gap". Definitely I agree with the safety contact, but traditionally with 700S-CF relays, they only go up to 10A. http://www.ab.com/en/epub/catalogs/12768/2...29737/tab4.html Looking for a 14A rating is tough in a control relay. I'll check the other solutions, but looks like this one is limited the higher amperages you go.

geez, I got my first look into a compact logix this week. Man, that's a tough way to think...how you can address your tags, and have structured tags within tags within tags....that's like a triple array!...whew... The guy who programmed this didn't bother with any descriptions in the "memory" tags and his short hand for symbols is a little less than desired.... like this one: "P15ONLT" what the heck does that mean... or "CS" grrr..... It's going to take some time to get use to the "free" reign of "memory allocation" in the PLC and structure it the way you want. I can see an advantage for it, but switching gears from 500 to 5000 is not something my brain can change too over night. Anyone have any other tips they want to share? I kind of didn't see a "used and unused" memory map. I guess you don't really need it. But if you had a tag that was configured as INT, with 16 bits, how do you know which one of those 16 bits you haven't used yet? The tag structure is tough to get a handle on too for me. I guess I will learn it as I go onward. I am just jumping in with both feet and no pointers at this point. The just "wing it" method...

Thanks

I did Halloween with a PLC, see my 2005 PLC Video: But like you, I switched to LOR for X-MAS. Here is my Christmas display with LOR (Light-O-Rama) http://www.youtube.com/user/chakorules#pla...s/6/RjwSCv3xbYs All my videos, displays, robotics.... http://www.youtube.com/user/chakorules

Anyone happen to make it up to the robot and vision show in Chicago? Did you see Motoman's SDA10 15-axis robot? I didn't go, but I heard it was kewl, so I looked it up. Amazing... http://www.motoman.com/datasheets/SDA10.pdf

Basically you have two choices for the InView Screen. Where you can switch a pre-determined message (the easiest) or Where you update a variable embedded into a message (little bit more work). Let me explain the easiest option first so you can get the hang of it. To switch messages: Just type your message using the inview software with no variables. Type it out normally, change the font, make it bold, change colors any way you want. Like in my article example, I created a message that said "OVEN JAM" http://www.mrplc.com/kb/Image/Image/ce-ab-inview-037.jpg "Message #5" Now I recommend creating a string array. Create a STRING array of 10 to start. In array My_String_Array[1] put the following ascii string: $141$r just type it in the array manually. Now write some ladder logic to copy the My_String_Array[1].Data[0] to your inview[1]. This will instruct the INVIEW to display message #1 you wrote in the screen software. To trigger or send the string to the screen, you need to toggle the bit inview[0].0 in your case. This will force the inview to read the string $141$r and change the display to message #1 If you want to change the screen to message #2 in the inview software, then I recommend In array My_String_Array[2] put the following ascii string: $142$r just type it in the array manually. Now write some ladder logic to copy the My_String_Array[2].Data[0] to your inview[1]. This will instruct the INVIEW to display message #2 you wrote in the screen software. To trigger or send the string to the screen, you need to toggle the bit inview[0].0 in your case. This will force the inview to read the string $142$r and change the display to message #2 Try this first, just making the inview screen toggle and change messages. Once you get the hang of that, I'll write more about how to update varibles in your messages....

I wrote an article on this. http://www.mrplc.com/kb/index.php?article=85 See if you can get what you need from it.

http://apps.detnews.com/apps/multimedia/pl...dex.php?id=1189 What do you think?

Can you elaborate part numbers with this statement in the article posted: "The software can be used to program the Micrologix 1000 and 1100" It use to be, the starter version would only program the 10-point Micrologix 1000. Has this been changed to program more part numbers besides the 10-point? Thanks for offering this to the MrPLC community.

I seen this via e-mail. Why would anyone do that? I guess not everyone is educated about electricity.

EVMOVE USB version should work too: http://forums.mrplc.com/index.php?autocom=...mp;showfile=490 Install your USB thumb drive into the computer FIRST, then run EVMOVE USB. You can then move your key to a USB THUMB drive.
