PROFIBUS Data Transfer Status
This is a 16-byte array with bit fields where one bit is assigned to
each slave station address. The associated bit is set if the slave
has reached or retained the "Data Exchange" state at least once
during the last three data cycles. For the bit/slave relationship,
refer to the Slave List Structure below.

PROFIBUS Slave Diagnostic
Status
This is a 16-byte array with bit fields where one bit is assigned to
each slave station address. When a slave leaves the "Deactive"
state for the first time, the associated bit is set. This bit is then
cleared when the slave enters "Data Exchange" state. If a slave
indicates "Extended Diagnostics" when it is in "Data Exchange"
state, the associated bit is set. For the bit/slave relationship,
refer to the Slave List Structure below.
