Transport

Select the value TCP/IP for a TCP socket (stream) or select the value UDP/IP to use a UDP socket (connectionless datagram)

Listen for connections on port

Use this option to wait for new connections in a specific IP port, common in Slave Drivers. If this option remains unselected, a Driver connects to the address and port specified in the Connect to option

Share listen port with other processes

Select this option to share the listening port with other Drivers and processes

Interface

Select the local network interface, identified by its IP address, that a Driver uses to establish and receive connections, or select the value (All Interfaces) to allow connection in any network interface

Use IPv6

Select this option to force a Driver to use addresses in IPv6 format on all Ethernet connections. Leave this option deselected to use the IPv4 format

Enable 'ECHO' suppression

Enable this option to remove the echo from received data. An echo is a copy of sent data, which can be returned before a reply message

IP Filter

List of restricted or allowed IP addresses from where a Driver accepts connections (Firewall). Please check the IO.Ethernet.IPFilter property for more information

PING before connecting

Enable this option to execute a ping command, that is, to check whether a device can be reached on a network, for a device before trying a socket connection. This is a quick way of determining a successful connection before trying to open a socket with a device. The time-out of a connection with a socket can be very high. The available options are:

•Timeout: Specify the number of milliseconds to wait for a reply from a ping command. Users must use a ping command to check the normal reply time, configuring this option for a value above that average. Usually this value can be configured between 1000 and 4000 milliseconds, that is, between 1 (one) and 4 (four) seconds

•Retries: Number of retries of a ping command, not counting the first attempt. If all attempts fail, then the socket connection is aborted

Main IP

Type the IP address of a remote device. Users can use an IP address separated by dots, as well as a URL. In case of a URL, a Driver uses the available DNS service to map that URL to an IP address, such as "192.168.0.13" or "Server1"

Port

Type the IP port of a remote device, between 0 (zero) and 65535

Local port

Select this option to use a fixed local IP port when connecting to a remote device

Backup IP 1, 2, and 3

Indicate the IP address, the IP port, and the fixed local IP port of up to 3 (three) backup addresses of a remote device
