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.
