So for the last few weeks I have been communicating with my PLC's just fine. We use 10.10.10.10 mask 255.255.255.0 on our PLC's. For my laptop I set an IP of 10.10.10.250 mask 255.255.255.0. It has worked fine until today. I was not able to ping my PLC. Finally got IT involved and after a while he was able to get them talking, and what he did was set the mask on my laptop to 255.0.0.0
Can anyone explain to me why this would fix the problem? I also don't understand what could have caused this problem because I haven't changed ANYTHING on my laptops network settings since the last time I went online with a PLC. Can anyone shed some light on this for me? I am having a really hard time wrapping my brain around subnet masking...
