The CNX Gateway is not necessary when using RS-232 serial communications.
TCP/IP connections between the server and the control systems require that each
side of the connection be provided with the IP address of the other. This kind of
connection also requires the use of the CNX Gateway which is separately licensed
software that facilitates communication between the server and the control system.
The CNX Gateway is typically installed on the server (when sufficient TCP/IP
sockets are available) or it can be installed on any computer visible (
i.e.,
pingable) on
the TCP/IP network. There only needs to be one Gateway running on one computer
to service the needs of all the computers and CNX control systems on the network.
However, multiple Gateways are perfectly permissible as long as they are run on
different computers.
