  1. 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. The software I have was downloaded from the argentinean schneider site, here is the address: http://www.schneider-electric.com.ar/sitio..._2003/index.htm You only need to register without cost and then you can access to downloads section. In this section, in addition, you can download other additional softwares and manuals.

  3. William, you can attach a signal converter between RTD and PLC in order to make a stronger connection and minimize the signal losses. In my job we have used this converter to drive thermocouple signals and send them to 1747-NI4 input modules: ULTRA SLIMPAK #G428-0001 The manufacturer is Actions Inc. I think this device could drive RTD signals. You can check its info. Regards!

  4. Have you verifyed the communication speed? Maybe this is the problem. Is possible too, that the communications port form PLC could be programmed as user mode (and is necessary the system mode to communicate with AB devices)

  5. If you need is a screen protected with password, I hope this help topic be useful. This help topic is from the PanelBuilder Software: Secure a screen You can restrict access to specific screens in an application by requiring authorized operators to enter a password. 1 In the Screens folder of the Application Window, click a screen. 2 On the Screen menu, click Properties. Or right-click and select Properties from the shortcut menu. 1 Select the Secured check box if you want to restrict access to the current screen. 2 To authorize specific operators to access the current screen, select the Operators tabs and then select the appropriate check boxes. A cleared check box denies access to an operator. Notes · Operators and passwords are defined on the Operators tab of the Application>Security dialog. · You can also secure screens from the Secured Screens Info tab of the Application>Security dialog. Screens folder The Screens folder is located in the Application Window. This folder contains a list of all screens in the applications. Screens appear in sequential order, by number and name. To open the Screens folder, click + next to the folder. To close the folder, click -.

  6. I agree completely with snerkel's point of view. I have a few experience in RSLogix, NAiS, Keyence, S7,PL7, and DirectLogix and for all those softwares I found most friendly the AB software. In fact, with S7 is easy to work (for me) almost as RSLogix. I think that depending the software we used to program, is the preference for everyone. For example, NAiS is too hard for me, but for a partner (who used to program in NAiS) this software is wonderful Did you understand me? Regards!

  7. Hi! Did you check if you can connect the PLC 5's using DF1? From your post, I understand you have connected only 1 plc in each PC. In my plant we had a similar case, when we tried to buy new KTX cards, we found only PKTX from our supplier, and in the old PC's we used, we only have the old type slots. Due we have a lot of PLC's connected in network in each channel, we decided to keep the old PC's and tried to improve the application we used (WW InTouch) with good results.(debugging the code) I hope this words be useful for you. Regards!

  8. When I need to register PLC changes in a Word document, first, in the RSLogix ladder I follow these steps: 1.-Select the rung to copy, 2.- type <CTRL-C>, 3.- In an open Paintbrush file, I type <CTRL-V> as a block, 4.- I type <CTRL-C> again, and finnaly, 5.- In a Word document type <CTRL-V> to paste the rung copied from RSLogix. It applies for ALL RSLogix (5,500,5000) programs I use I hope it be useful for you

  9. 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...
