Appendix 2 Request Code Table

This table lists the request codes (CMD) used with SEND/RECV instructions sent to the Ethernet
Port. Refer to the section/item indicated in the reference column in the table for detailed
explanations of the request codes.

The request code (CMD) types (1) to (3) have the following meanings.
Class (1) is module control, (2) is PC link protocol transmission, and (3) is socket interface
transmission.
For a single Ethernet Port, it is not possible to request another class (1) CMD while a class
(1) CMD is executing. This is also true for class (2) CMDs. If such a request is issued, the
status will be transmission port busy, and the request will go to the wait state.
For a single Ethernet Port, when requesting a class (3) CMD, it is not possible to request
another class (3) command for a socket for which an instruction is executing. If such a request
is issued, the status will be transmission port busy, and the request will go to the wait state.
There are eight sockets, and each can independently accept and execute a class (3) instruction.
