Hi everybody, I'm in the process of replacing my old laptop and I would like some advice on what to buy. I need a good laptop for PLC's and control works. I would appreciate any help.

Look at NEC Art 725, and NFPA-72 Class 1, Class 2, and Class 3 Remote-Control, signaling, and power limited circuits. As a rule of thumb, 24 VDC is commonly used for control and low voltage signaling, it is safer and a lot easier to work with.

Thanks a lot Ken.

Hi folks, Can anyone please give me some information about what cable to use to communicate with PowerFlex 40, PowerFlex 70, and PowerFlex 525.? I don't find this information on Rockwell side. Thanks, Robert.

I found it on Rockwell, 1203-SFC, but my vendor says it is obsolete and that I should contact Tech support for a possible replacement. Do anyone knows the replacement part number? What cable are you guys using to communicate with any DataFlex Drive? I would highly appreciate any help. Thanks, Robert.

Hi Folks, I'm retrofitting an old machine and I need to index two cylinders, cylinder #1 will be keep extended to hold the part in place while cylinder #2 is retracted. After a few seconds, cylinder #1 will retract to let the part go to the next position on a downsream conveyor and cylinder #2 will extend and retract for a feaction of seconds then cylinder #2 will extend to hold the part in place to repeat the sequence . In orden to acomplish this, I'm planning to use two timers to index the cylinder on extended/retracted positiion. Is there a better way to do this? I'm usin a MicroLogix 1200. I would appreciate any help. Thanks, Robert.

Hi Folks, I have a tough decision to make. In my facility I have three PC's running Windows XP with RSLogix500, RSLogix5000, Factory Talk ME, and Panel Builder 32, and my employer wants me to upgrade these PC's with Windows 7 or Windows 8. They also want me to upgrade RSLogix500 V7 to RSLogix V8, RSLogix5000 to Studio5000 RSLogix5000, and Factory Talk ME V5 to Factory Talk V7. My questions to you guys: Which OS is better Windows 7 or 8? 32 0r 64 bit? Service Pack 2 or 3?. Any help will be greatly appreciated.

Hi folks, Do you know where I can find the set of Instructions that used to be here in the PLC Guide? These instructions, JPS, JRS, SBR, TON, CTU, SQO, LCD, RET, GRT, SUB, LES, ADD, OSR, NEQ, MOVE, CLR, FLL, etc., etc. are good handy tools when programming but it looks like there were removed. Does anybody know where it can be found? Thanks, Robert

Thanks, TW

Thanks a lot guys.

Thank you very much, ASForest.

Microsoft is not longer supporting Windows XP and I heard some people having isssues with Windows 8 or Wndowa 7 when running RSLogix500 or RSLogix5000.

Thanks Ken, I have mistakenly written Studio 500 RSLogix500 V21. This is wthat I thought but I wasn't sure about DriveLogix, FlexiLogix, and SoftLogix 5800 Controllers.

Hi folks, Can someone please tell me the differences between Studio 500 RSLogix500 v21 and RSLogix5000 v20? I'm confused about their application. Any help will be greatly appreciated. Robert.

Thanks Mickey.

Hi Folks, I need to replace an AB 1746 -NO4/A SLC-500 Analog Output Module, it's giving me inaccurate signals to the VFD that controls the speed of the main motor. I have uploaded the application program but I don't know if this particular module needs to be reprogrammed before it's inserted into the chassics. How the processor will recognize it? Does anybody can help me with this procedure? Any help will be highly appreciated.

Thanks a lot

Hi Folks, I'm in the process of buying a Factory Talk Machine Edition 15 Displays software for my current employer, and I was told by the vendor that it can be upgraded to 30 Displays from Rockwell site. Does anybody have done this before? The 15 Displays edition is about $500.00 cheaper than 30 Displays edition. Any help would be highly appreciated.

Yes, I was able to download the application program. Thanks

Hi Folks, I'm trying to download an application program to a 1746-L40B AB processor but everytime I try I get a measeage " Processor isn't reponding". I'm using a UCI converter. This program was written using an old version of RSLogix500. Any help would be greatly appreciated.

Thanks Mickey, you information was very helpful.

It looks like RSLinx makes connection since I can see the driver, DH85 UIC and the Processor, but it only shows node 0, then it shows node 1, 2, 3, 4, no found. Then when I open RSLogix500 and try to download the application program I got the following message "Processor no responding". I suspect I may using the wrong cable between the UIC and the processor. I picked up this cable from Radio Shack.

Hello everybody, I'm need to buy an omron CX-one software and I'd like to know what's the latest version. Can someone help me out? Thanks. Robert.

Thank for your help guys. What's the difference between Syswin and CX-One? I don't know which one to buy.

Thank Michael
