Composer Elite Operating Manual
5.4.1.7 Acknowledge Handler Object (2Bh)
The supported services are:
 Class - Get Attribute Single (Revision, UINT, 0001h)
 Instance - Get/Set Attribute Single
5.4.1.8 I/O Data Format Object (64h)
The I/O Data Format Object is a vendor specific object used to determine how the
contents of the Assembly Object buffers are formatted and used. The Composer
Elite Output (CE OUT) and the Composer Elite Input (CE IN) can be used to
exchange INFICON messages. Alternatively, the Composer Elite Output (CE OUT)
can be used to cache a predefined set of data values.
Per the Composer Elite Cache Data Sets (see section 5.4.2, DeviceNet Data Sets,
on page 5-12 ), all INFICON data sets are formatted per these byte tables and
accessed via the Assembly Object (04h, Instance 96h). The Composer Elite will
continuously update these data values as the values change. A change indicator
in the form of a count field will be maintained to indicate when the values may have
changed. Also, an update in progress indicator is given to indicate when a data set
could be partially updated. The data set currently published is reported to help the
host correctly interpret the data present.
NOTE: The data set functionality is only available when a Polled, COS, Cyclic or
Bit Strobe connection is detected.
