You can connect the control with your plant's intranet or use a transposed
cable to connect directly with a PC. The data transfer rate is dependent on the
amount of traffic at the time on the net. For information on the pin layout, see
Chapter 3, "Mounting and Electrical Installation."
Maximum cable length:
Unshielded: 100 m
Shielded: 400 m
Network topology: Star configuration
This means a hub serves as a central node that establishes the connection to
the other participants.
The control requires an NFS server (Network File System) or a Windows PC
(SMB = Server Message Block) as the remote station. It must operate
according to the TCP/IP protocol principle.
