Access control

access to a CP via IP-List. The access control only influences the transfer
of project data via WinNCS res. from PG into CP and CPU.
The normal data transfer between CPs and PGs is not influenced.
By means of the IP-List you may exclude or include IP addresses res.
address ranges for the project engineering. The access control is only
active when you choose "WinNCS" or "PG" or both.
The IP-List is transferred together with the CP project engineering.
