c.UDP send request

This program issues a UDP send request for socket number 2 on the Ethernet Port.
This ladder program is executed by turning on the A contact on the R0622.
	Parameters:		12544: 3100H, 00050: 0032H
			0341995909: 14627185H
	Transmission destination IP address: 133.113.98.20
	Transmission destination object socket UDP port number: 3000
	Transmission data word count: 1000
	Transmission data storage registers: D1000 and above

	/* UDP send request: executed when R0622 is set on. */
