WHEN COMMUNICATING DATA USING THE MC PROTOCOL

9.1.2 Message format and control procedure

This section explains the message format and control procedure.

(1) Message format

This section explains the message format for transmission between the Ethernet
module and an external device.
The communication data consists of "header" and "application data" as shown
below.

(a) Header

The header for TCP/IP or UDP/IP is used. The user does not need to specify
it; the Ethernet module attaches it.

(b) Application data

The application data is largely divided into "subheader" and "text" as shown
below.
The subheader represents command/response and the setting value is
predetermined.
The text contains the request data (command) and response data
(response) for each function and this data is determined by the prescribed
format (for a more detailed description, see sections 9.3 and later).

(c) Format in the application data field

• Communication in ASCII code

• Communication in binary code

NOTE

When communicating in the MC protocol, the user does not need to specify a
response for a command from an external device; the Ethernet module generates it
and then responds.
