Set system 901F
I have a PM901F CPU which I can't set the system time in (it's only one CPU in this network). The version of Freelance is 2016 SP1 with RU2. Operating system in the computers are Windows 10.
I have read earlier questions similar to this case.
Subnet mask is 255.255.240.0
When I try to set the system time it looks like below
I press "Ok" and every thing seems to work.
If i look at the CPU:s time variable it tell me that nothing have happen. The system time haven't changed at all.
Is there anyone who can tell me what to do? Maybe I have forgot something?
