8.5 Network variables
Network variables are a way of transferring data between two or several
controls. Currently network variables are implemented on the basis of UDP.
The variable values are transferred automatically on the basis of broadcast
messages. These services are not confirmed by the protocol, i.e. there is no
control whether the message actually reaches the recipient. The network
variable transfer corresponds more to a 1 (sender) to n (recipient)
connection.
The libraries "NetVarUdp_LIB.lib", "SysLibCallback.lib" and
"SysLibSocket.lib" have been inserted into the library management of
CoDeSys.
8.5.1 Settings in the target system
Enable the check box "Support network variables" in the tab "Network
functionality" of the dialog box "Target settings". Enter "UDP" under
"Names of supported network interfaces".
