(2)Transfer parameters (A)

The data required for a request to the Ethernet Port is set up in an area that starts in the register indicated by [A]. Then the application executes a SEND or RECV instruction. Here we present an overview of the structure of the transfer parameters. Tables 4.1 and 4.2 list the requests that can be issued to an Ethernet Port.

A

A + 1

A + 2 A + 3

M

3100H

CMD

Parameters

Module designation

 

Command number:

Indicates the request type to the Ethernet

 

Port.

Parameters:

This data differs depending on the type of

 

the request to the Ethernet Port.

Module designation:

Designates the Ethernet Port mounted in the T2N.

3

(Module ID):

Must be set to 3 for an Ethernet Port.

1

(channel number):

Must be set to 1 for an Ethernet Port.

00 (station number):

This two-digit field must be set to 00.

<Important items>

e.Do not modify the contents of the transfer parameters while an instruction execution is in progress.

The SEND or RECV instruction may not complete.
