• capture PLC-data in our LAN

    Our PLC-vendor is going to provide us collected PLC-data on a server in our LAN. Are sockets (port higher then 1024) the best way to do this? As we are AS/400-minded people, will FTP resolve this with the same performance? Or are there other possibilities? Please, please, give us some guidelines.
