Socket functions

Socket functions are used for communicating over a cellular network or LAN.

Please see the example program (shown for each function).

The sock() functions uses TCP/IP.

	•sockConnect	Initiates a socket connection
	•sockConnection	Returns the current status of a connection
	•sockDisconnect	Disconnects a socket
	•sockGetLocalIP	Returns the local IP address
	•sockIPFromName	Converts a string to an IP address
	•sockIPToName	Converts an IP address to a string
	•sockListen	Listen for a connection
	•sockReceive	Reads data from the connection
	•sockSend	Sends data over the connection

The UDP socket functions are used for communicating over the internet via IP-networks. The udp() functions use UDP/IP.

Please also see the example application section for examples.

For NX32L based devices it is recommended to use the Advanced so socket API.

IP address format:

In all places where an IP address aaa.bbb.ccc.ddd is stored in a DINT, the following format is used:

ddd is stored in bit 24..31.

ccc is stored in bit 16..23.

bbb is stored in bit 8..15.

aaa is stored in bit 0..7.
