Unpassive Open Mode
To use unpassive open mode, set the connection parameters as follows:
• Set the IP address of the remote station (Node IP Address) to 000.000.000.000.
• Set the port number of the remote station (Node Port) to 0.
In unpassive open mode, the 218IFD connects to any station that attempts to access the rele-
vant connection number. If more than one station attempts access, the connection will be
established with the station that sent the connection request first.
When a connection is established in unpassive open mode, a connection request from another
station will break the current connection and establish a connection with the station that sent
the connection request later.
