6 Configure the Operation Modes
The configuration as Server (top part) requires the same parameters as the Driver Mode, hence
TCP Port(Control) and TCP Port(Data). Also the KeepAlive function operates the same.
The configuration as Client (bottom) first requires a destination. Here it is given by name, but a
direct IP Address may be more usual. On the destination there is also a TCP Port(Control) and
+
TCP Port(Data) to accept the connect of the NetCom .
The Connect methods are the same as with the TCP Raw Client mode. So connections to the
partners are permanent, last until there is no activity for a given time, or they are controlled by
the DSR signal.
+
Attention: You must not configure both NetCom with a Connect option configured as Permanent.
+
This will result in each of them attempting to contact the other at the same time. Both NetCom
will reject the connect, because they are already busy establishing a connect of their own. Instead
+
create an asymmetric configuration: either use one of the NetCom in Driver Mode, or configure
it with an empty Destination parameter. Or consider to have a connection on demand, i.e. use the
Triggered option.
