Composer Elite Operating Manual

5.4.3 DeviceNet INFICON Messaging

All information exchanges are formatted and accessed via the Assembly Object
(04h, Instances 64h, 96h). Transactions with Composer Elite follow the form of
Host setting the Assembly Object data field (CE IN data) following the content
below (starting at

section 5.4.3

) and when the change indicator (Transmit / Receive

Message Count field) changes the response content is ready to be read out. Each
new command (CE IN data) must update the Transmit / Receive Message Count
field to signal the Composer Elite communications process that a new command is
pending.

NOTE: The body of the CE IN and CE OUT data block (bytes 2 … n) after the

Transmit / Receive Message Count field are identical to messages
exchanged over RS-232.

5.5 Message Format

Standard message protocol serves as a structure for the contained command or
response information. It also can provide a level of acknowledgment between the
host and server and a mechanism for verifying the information content.
