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.
