Technical support / Computer(s) won't see PLC any more - Please help
« on: September 07, 2007, 03:48:10 PM »
Hi,
I hope someone can help! We have programmed the PLC, and have been communicating with the computer via a 9-pin RS232 cable. Things were working fine, and we updated the program successfully several times. Now, however, the computer will no longer recognize the PLC. We have tried using a different cable, and we even tried two other computers. We have a critical update that has to be done, and we can?t get to it.
Thanks for your help! You can?t imagine how happy we will be when we solve this!
