Two ES in One PCS7 Project

Hello everybody,

My question is about considering two ES in one PCS7 project (not in multi-project). Is it possible to have two ES connected to plant bus and also terminal bus with two different IP address? In that case, if it is necessary to install ES/OS single station on each station with different license or one license can be installed on both station? Also how I can transfer any data change from one ES to another ES? is transferring data possible with selecting relevant station and download command?

thanks in advance
Yes it's possible ... you have to put the project in a share directory … and then you open the project on the both ES …. But for compiling the CFC, you don't have to edit in the same time, CFC of the some PLC ...
