5.4.2 DeviceNet Data Sets
5.4.2.1 Initialization
After a power cycle, Composer Elite will default to expecting and responding to
INFICON messages. To instruct Composer Elite to cache data in CE OUT instead,
in the host computer set the I/O Data Set attribute to a non-zero value. The value
will specify to Composer Elite which data set to cache. This value can be changed.
When Composer Elite is caching data to CE OUT, CE IN is not used.
NOTE: Switching data sets, or between INFICON messages and a data set, may
take a few moments to complete.
