6.8 Connecting with Expansion Unit
6.8.1 Connecting with I/O Device Using PROFIBUS-DP
This unit functions as the PROFIBUS-DP master station.
In order to connect with I/O device by using PROFIBUS-DP, expansion unit (FCU7-EX891) and
PROFIBUS-DP unit (FCU7-HN571) are required. Mount the expansion unit on the right side of the control
unit and PROFIBUS-DP unit in the expansion unit slot.
Use dedicated cable for the PROFIBUS-DP and connect to the NET connector.
When installed at the end of the network, turn the terminator slide switch ON. In all the others cases, the
switch must be turned OFF.
When setting parameters in the PFOFIBUS-DP unit by using configuration software (parameter setting tool),
connect PROFIBUS-DP unit and personal computer (PC/AT compatible) with RS-232C cross cable. At this
time, configuration software must be installed in the personal computer.
