Hi group
I had successfully established a connection earlier today but I goofed something up and have now been banging my head against a wall for hours.
I can connect to the PLC easily with Comm 2 (RS232) but not ethernet.
Can someone tell me exactly how to set the settings in both my laptops ethernet adaptor (manually set an IP address and subnet mask, I assume...but what about DHCP) and also in the Channel configuration screen for the ethernet port in the PLC. (BootP, DHCP, etc...I read that BootP should be disabled) I have been changing the settings for that port in my application program using RS Logix then downloading it to the PLC using RS232...I do a PLC power cycle and the PLC is running the revised program no problem but I still can never get a proper ethernet connection in RSLinx. Best i have been able to do is (in RSLinx) it shows a semi-ok connection-- the model # of the PLC appears but the yellow question mark remains. I have tried both a standard cable and a crossover cable. I even loaded a fresh (empty) application program which had default settings for the e-net port...no luck...Any help would be very much appreciated.
