PROFIBUS connection
Here we recommend users to
use the standard PROFIBUS
cable and connector (DB9
male). It is only needed to use
D-type connector via
PROFIBUS cable to connect
PROFIBUS Master station and
I-7550E module. PROFIBUS
Master station and I-7550E
module belong to terminal
equipments in this example, thus we need to enable the terminator resistor in
the D-type connector.
Address setting
The I-7550E is a slave device of PROFIBUS DP protocol. The station address of
I-7550E can be set by DIP switch. The DIP switch can be seen by open the
cover, as shown in the below. The range of DIP switch is 0~126, here we set I-
7550E module’s DIP switch to 1.
