5.3.7.Map Descriptor Example 4 – Default Variation (Variation zero)

If a remote Client polls for data of a particular type and the variation is set to zero then the request is for the Server’s default variation. For the FieldServer, the default variation is always 1. This means that requests for variation zero will fail unless the Server contains a Map Descriptor where the variation is 1.

With Data Objects of variation 1 defined the Server can respond to requests for variation zero.

Such requests are polls for the default variation. The default is 1 for this driver.
