I recently discussed with some guys what would be the best underlying infrastructure for the PI-System (PI-Server, AF-Server, Coresight, DataLink). The existing network structure is as usual:
- Office Net (Company Domain Controller -> In Operation)
- Production Near Net - for PI-System and OPC-Server (NEW DOMAIN or Company Domain??? -> To be decided)
- SPC/DCS Net (without Domain Controller -> In Operation)
The dispute was about having an extra domain for the second layer (Production near network), that was put into place deliberately for the PI-System. Are there some PROS and CONS?
The second request for help was the question if Coresight should be operated in network layer ONE or Network layer TWO? Are here pros and cons too?
Thanks in advance for your help!
