The transmission program will run when I000000 is ON, provided that the Network Instruction Enabled Flag for port 7 is ON and the RECV instruction has not been executed.

CIO 120000H remains ON while the SEND instruction is being executed, and it turns OFF when the execution of the instruction has been completed.

Word	Content		Meaning
D00000	00	0A	No. of send words: 10H
D00001	00	02	Destination network address: 2
D00002	04	00	Destination node address: 4
			Destination unit address: 0
D00003	07	05	Response required
			Communications port no.: 7
			Number of retries: 5
D00004	00	64	Response monitor time: 10 s

The 10-word data starting from I0000 is stored in D00010 and following words.

Transfers 10 words of data from the source node (D00010) to the PLC (from D00020 onwards) at network address 2, node no. 4, unit address 0.

Creates reset input.

Transmission error display

The reception program will run when I000001 is ON, provided that the Network Instruction Enabled Flag for port 7 is ON and the SEND instruction has not been executed.

CIO 120002H remains ON while the RECV instruction is being executed, and it turns OFF when the execution of the instruction has been completed.

Word	Content		Meaning
D00005	00	10	Number of receive words: 16H
D00006	00	03	Destination network address: 3
D00007	20	00	Destination node address: 32
			Destination Unit address: 0
D00008	07	05	Response required
			Communications port no.: 7
			Number of retries: 5
D00009	00	00	Response monitor time: Default

Transfers 16 words of data (from A100 onwards) from the PLC at network address 3, node no. 32, unit address 0, to words 2000 onwards.

Creates reset input.

Reception error display Reception data processing

When the data is received without an error, the 16-word data received at CIO 2000 and following words is stored in D00040 and following words on the same PLC.

Note When using the sample program, make sure that the bits and words used in the sample program are not the same as those in the user program or Special I/O Units.
