  1. Hi everybody: I have one ESA panel VT505W. I have the original program but I can't open it because it was made with an old version of ESA Polymath. As I know I should open the proyect with the version 1.7, compile it and then work with the new version. I have been looking for ESA Polimath V1.7 without any succed. Does anybody have this versión?? Does anybody know another way to open this old proyect? Thanks
  2. Allen Bradley 1756-L1 can´t go online

    Today I could try what you have said. I have mounted one of the new cpus on the backplane and through its serial port I have been able to connect to the cpu that had the program and upload it. Once I downloaded the program I have found that the serial port was configured as User mode, for ASCII protocol, making it impossible to communicate with the plc once you download the program and the plc starts running. Fixed issue. Thank you very much to you both for your answers. They have been very helpful. Regards.
  3. I'm new arround here so first of all greetings to all and apologies for my English. I tell you the case: I have a machine that has an Allen Bradley PLC 1756-L1 (yes, it's already a bit old) communicating with another plc, a B&R 2003, through the serial port. I wanted to download the program from AB. I open RS-Linx, I create a DF-1 driver and then click on autoconfigure. At this point I get an error saying RS-Linx can't find the communication parameters. I tried to connect with two other cpus 1756-L1 that I have (these are new so they don't have program) and the RS-Linx locates them perfectly. I guess the ab cpu has its serial port configured as USER to communicate with the B&R plc (or something similar), so my question is if there is a way to connect to this cpu through the serial port (such as putting the serial port in default mode without deleting the program) or the only option left is to find an ethernet card to connect to the cpu. Thank you very much for any answer because I've searched a lot and I don't find any information about this.
