CONNECTOR PINOUT

The Profibus DP-V1 communication module has two connectors to the Profibus network, each one with the
following pinout:

INDICATIONS

The alarms, faults and status indications are done through the device HMI and parameters.
2.4

DIP SWITCHES

At each segment of the Profibus DP network, it is necessary to enable terminating resistors at both end points
of the main bus. For this purpose, the Profibus DP communication module has two DIP switches that can be
activated (both switches to the ON position) to enable the resistor. The DIP switches should not be activated if
the network connector already has the terminating resistors.
