Cyclic Communication Data Description
The following sections describe the device variables involved in cyclic communication. Most of
these variables contain a data part and a status byte. The status supports 2 different sets of
coding: the classic status and the condensed status. The condensed status offers gradual
prioritized information which is the most suitable to support you with process control and
maintenance tasks. Whereas the classic status follows a fixed mapping between failure cause
and status message, the condensed status can be configured depending on available failure
causes. For more information, refer to the device type manager description on diagnostic and
status mapping.
