  1. Connection with a CPM2A PLC

    Hi! Who knows how can I connect a PC to a CPM2A PLC using the PLC's serial port? Because I lost the original communications cable for this PLC (CQM1-CIF02) And I believe this cable is connected by the peripherial port (I never used the cable and don't remember what kind of connectors it have) And we can't get another new cable because I need to check quickly an error in the PLC's program Thanks a lot by your help!

  2. Hi, Everybody! I haven't experience in Modicon PLC's, I'm most involved in AB, but, in a TSX Nano I need to change in the program one output, since it is damaged. I got the PL7/07 software & cable, but when I tried to transfer the program from PLC to PC, a message appeared like 'Program protected' Reviewing the manual, I found that it is an option when the program is downloaded to PLC. The question is : Is possible to upload the program, even with his protection? Probably exists a jumper inside the PLC like in PC's, is it possible? I will be really thankfull if you can help me... Best Regards from Mexico...
  3. Hi all! After a long time... now I am back in the source... This amazing forum Now I'm developing an application with VB.Net and WinCE (handheld PC) and I need to communicate with a SLC 500... Usually, if i'm working in a PC, I install Rsling and configure a driver(serial, ethernet, DH or whatever) but i don't know if exists a RSLinx version for this environment, or if normal rslinx can work Could you tell me if it is possible?? Thanks in advance!!! Best Regards from Mexico!
  4. 1747-PIC Equivalent

    B&B Electronics have a replace for only 169.95! Its model is 232ABRJ45 http://www.bb-elec.com/product.asp?sku=232ABRJ45
  5. Wan Between Plc's

    nileshsurya: Maybe you can try using some ProLinx products. They have DF1 to RF or DH-485 to RF converters, and RF to -any protocol- converters, too. Check it from their homepage: http://www.prolinxgateways.com/ or more exactly: http://www.radiolinx.com/ Regards!
  6. Dh+ Network Load

    You can use a HMI in order to scan only alarm tags (I.E. WW InTouch or RSView) or even in excel, using an OPC Server like Kepware. Here in my job, we are monitoring all network using WW InTouch and this network is about 60 nodes.
  7. Basic question - need lil help!

    If you don't find the trial version, I have a copy and i can upload it in a free server, let me know if you want it. Additionaly, I can share a few manuals and example codes Regards!
  8. Loss for words

    In an application, I compare all the word and enable a bit. Maybe this logic can work for you: You only need an inverse logic. Regards!
  9. ROCKWALL?

    Maybe is a "pirate" PLC Like Raebook tennis shoes or Tommy Halfmaker jeans
  10. SLC 5/03 is not coming on network

    Hi, dude! With a similar problem I tried unplugging all PLC's from Network, and then connecting one by one, verifying that all PLC's are detected by RSLinx. This procedure works fine for me. Regards!
  11. ZelioSoft & TwidoSoft

    I have PL7 demo ver 4.0 (downloaded from Schneider site)
  12. Hi, all Now I need to work with a TSX Micro 3721001 PLC But my demo version of PL7 Pro can't upload or modify the PLC program And I also have TwidoSoft ver.1.13 and ZelioSoft, my question is: Can I use one of these softwares to program my TSX Micro? Or I need exclusively the PL7 software??? If someone of you can provide me a full version of PL7 I'll be greatful I already have PL707, but I think this software is exclusive for TSX Nano Is it right??? Thanks in advance Regards!
  13. PLC 5 Communication Problem

    Have you tried to go online witha PC, or with the laptop connected to AC power? Because I found a similar problem with my laptop. When I am connected with a laptop powered only with the battery,after a few minutes, the connection is broken. Then I connect the laptop to AC supply, and the connection works fine. I suppose that, because the battery power is decreasing, it don't support the serial connection. Try it. It could works. Regards
  14. Solid state relay to Plc input

    Maybe you have a wrong polarization for the PLC input. Check if it is PNP or NPN, and if it match the Opto22 polarization. Regards!
  15. You can use a temperature controller with a dual output. With the 1st output you can control temperature and you can set the 2nd output inverted, i mean when the setpoint is reached, this output is enabled to reduce temp, but you must connect a timer, such as mgvol said in his post. I have experience with love controllers, specifically Love 16A (it costs about $300) http://www.mod-tronic.com/Love/pdf/16A_data_sheet.pdf But Automationdirect have a substitute for this one: http://web5.automationdirect.com/adc/Shopp...rs/TC33-2010-AC Regards!
  16. In this forum exist an article about npn-pnp: http://forums.mrplc.com/index.php?act=Downl...&CODE=02&id=141 It was useful for me! Regards
  17. In order to keep your two devices connected, you can attach to PLC port a device from ProSoft which can duplicate DF-1 port, and then you can attach your panel and your PC. Their webpage is www.prosoft.com. You can take a view from it.
  18. single switch for turn on/off

    you can only enable a PLC output and connect it to a relay. Then in one N.O. contact connect the power supply of motor Here is an Example
  19. Hi All! Someone of you have an example of a program for a redundant system using SLC's (or another AB PLC)? This is because I'm involved in development of a redundant system, but I'm not sure about what kind of instructions could use, I think about MSG instructions is good, but, if i can use another logical sequence, or another special instruction. Thanx a lot!
  20. Redundant System with SLC

    For programming examples I mean, whether in order to keep both PLC's working together, is necessary some special instructions, like MSG, to "exchange" data between both PLC's. Did you understand me? I thank for your answer, Eddie!
  21. I have a doubt: TSX Micro is the same PLC as IDEC Micro? If it is right, then the PL7 Micro software can be used to program both PLC's Thanks
  22. Siemens components CAD drawing

    This is the file I have for S7-200 If you want drawings about other models, or you like this drawings in the original .dwg format, this is the page where I downloaded it: http://www4.ad.siemens.de/-snm-0135109872-...&objid=10860557 AutoCAD_pdf.zip
  23. Redundant System with SLC

    Thanks a lot! This info have been very helpful, mgvol. Best Regards!
  24. Redundant System with SLC

    Is possible to do this kind of control using SLC's? Because now I have only SLC's in availability. And, in addition, if you have a program example for this control, I'll be thankful.
  25. Hi, all I have a question: Did you know about some barcode reader with discrete outputs? Let me explain you: I have a NAIs PLC which need to know if a number is right. This number is a barcode printed in a label, and this number is necessary to start the process. So, i know that NAIs didn't have the capability to keep string registers entered by serial port (like entered by a barcode reader). So I think about a barcode wich I can program the valid codes and this reader coud set an output if the codes are right. What do you think about this? I'll be very grateful by you comments or suggestions.
