CompoBus/D Communications Card Operations	Chapter 5

Note Message communications are supported by CV-series and C200HX/HG/HE PCs, but not by C200HS PCs.

HOverview of Explicit Messages

Explicit messages are sent and received as described below. Basically explicit message communica- tions are executed in 1-byte (8-bit) units.

Content

Header

The header indicates the beginning of an explicit message and that the frame is an

explicit message request/response. It is set automatically for CompoBus/D

(DeviceNet), so there is no particular need to be concerned with it.

Node address

Request:

Set the node address of the Slave/Master to be requested.

Response:

The node address of the responding Slave/Master is set.

Service code

Request:

Set the code of the requested service (read/write, etc.).

Response:

The MSB (most significant bit) of the requested service code is

changed to “1” and returned.

Class

Function classification (major

Indicates the classification of a function

defined by DeviceNet. To specify a function,

specify these three codes.

classification)

Attribute

Attribute (Set values are assigned

for each function.)

Data

Request: Set the data to be written.

Response: Read-requested data or fault message are attached.

Footer

This is the part that indicates the end of the explicit message and executes the

CRC check. It is set automatically for CompoBus/D (DeviceNet), so there is no

particular need to be concerned with it.

5-2-2 Sending and Receiving Messages with C200HX/HG/HE PCs

HUsing IOWR

With C200HX/HG/HE PCs, explicit messages are sent using IOWR. To send an explicit message, it is necessary to place FINS command “2801” in front and to send the command to the Master Unit. The Master Unit that receives the command converts the command data to an explicit message and trans- fers it to the destination node. (When sending an explicit message, it is not possible to directly specify the destination node with IOWR.)
