(6)PC link protocol transmission (Data write)

The T series PC link protocol allows a T2N or T3H on a network to write register data to another T2N or T3H.

∙Register write request (using the SEND instruction)

(a) Function

The register data designated by the local station (T2N/T3H) is written to the designated register on the remote station (T2N/T3H).

(b) Transfer parameters

A	2¨	H
A+1	CMD = 0000H
A+2	Transfer Size
A+3	Register type (self-station)
A+4	Leading address (self-station)
A+5	Register type (target-station)
A+6	Leading address (target-station)
A+7	Response time limit

Module designation

Command number: Normally 0H; request to loopback 000FH

1)Transfer register data length: 1 to 128 words

2)Local station register type code

3)Local station leading address

4)Remote station register type code

5)Remote station leading address

6)Response time limit

1)Transferred register data length

Designates the transmission data length in word units. (1 to 128 words)

2)Local station register type code

This code indicates the type of register in which the local station transmission source data is stored.

3)Local station leading address

Designates the leading address of the register designated by the local station register type code.

4)Remote station register type code

This code designates the type of register at the remote station to which the transmitted data will be written. (see 7.3(6))Local station register code)

5)Remote station leading address

Designates the leading address of the register designated by the remote station register type code.
