12.4.1.3 Communication Rate and Distance
The communication rate range of the PROFIBUS DP is between 9.6K bps and 12M bps. The
transmission distance depends on the transmission rate and ranges from 100m to 1,200m. The
communication rate that Delta PROFIBUS product supports and the corresponding distance are
listed below.
Baud rate
(bps)
9.6K 19.2K 93.75K 187.5K 500K 1.5M 3M 6M 12M
Distance(m)

12.4.1.4 PROFIBUS Connector
The PROFIBUS connector used for connecting the PROFIBUS cable and stations is usually
classified into two types as below. No Delta PROFIBUS connector is available for user to purchase
currently. Users themselves need to choose the D-sub 9-pin PROFIBUS connector conforming to
the specification.
The internal structure of the PROFIBUS connector is shown as below. It contains one In hole for
input, one Out hole for output, one terminal resistor switch and 3 resistors. The In hole and Out
hole are connected to the previous station and next station respectively.
