Explicit Messaging Quick Start

To send explicit messages, the Epsilon Ei-DN drive should be configured and successfully connected to the DeviceNet system as a unique node. This chapter will present examples that should be used as a tutorial.

Equipment

Ei-DN DeviceNet Digital Drive NT 207 Motor

Allen Bradley SLC 500 PLC™, 1747-L542 (4 Slot Chassis), P1 Power Supply, 1747 SDN Scanner Card (slot three)

How to Send Explicit Messages

An Explicit Message is compiled using an integer file (for example N10). Format the message using the following table.

	Integer File N10	High Byte		Low Byte
	N10:0	TXID		COMMAND

Message Header	N10:1	PORT		SIZE OF FIELD

	N10:2	SERVICE		MacID

	N10:3		CLASS

	N10:4		INSTANCE
Message Data
Message Data	N10:5		ATTRIBUTE

	N10:6		VALUE LOW WORD

	N10:7		VALUE HIGH WORD

Once formatted, use the copy command to transfer it to the M0 file. The copy initiates the explicit message transfer from the scanner to the Ei DeviceNet drive. The Ei drive response will be placed into the M1 file by the scanner. Using the scanner message received status flag (in the example of this chapter the location would be I:3/15), copy the M1 file to an integer file (N11). Once the message has been copied, the results may be examined from the N11 file.

TXID is set at 0x01 for all of the following examples. PORT will be set to 0x00 indicating a 1 port network.
