26 41 PROFIBUS Slave Configured List This is a 16-byte array with bit fields where one bit is assigned to
each slave station address. The associate bit is set if the slave
is present in the database. For the bit/slave relationship, refer to
the Slave List Structure below.
42 57 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.
58 73 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.
