Twincat System Manager & PLC Control, Beckhoff BC9020

1 post in this topic

Hi, I have a problem with my BC9020 and hope that someone can help me. I managed to set the IP adress of my PLC in the 10.2.5... add a root, run a program and make the PLC working for a while. I then tried another program, a new one... and now that I want to re-read the first program, Twincat System Manager doesn't allow me to enter in the "run mode" and stays in "config mode". It also has lost the IP address I set (10.2.5.....) and came back to the 172.16.22... (manufacturer settings) I cannot determine if the problem is in the PLC Control or In System Manager... This is my method to change the IP *** IP config *** 1) Reset the PLC First I place the end terminal next to the PLC. I set the DIP switches 1,6,7 to ON, power on the PLC and power off. I set the DIP switches 2,6,7 to ON, power on the PLC and power off. I set the DIP switches 1,2,6,7 to ON, power on the PLC and power off. 2) Set my PLC on the same AMS than my own IP (172.16.22...1.1) 3) In System Manager, add a new route 4) change the setting in I/O Configuration -> I/O Device -> Device 2(BX9000) -> clic on BX9000 define "set IP Address" to Manual define " IP Address" to 10.2.5...., the AMS change automatically. Press the configuration button and then Ctrl+F4 (run mode) This method worked but seems not to be the best... If you have any Ideas ? or questions? Thank you in advance Gregi
