PROFIBUS via M12 plug connectors
INFORMATION
This example is valid for ABOXes with PROFIBUS plug connectors.
The following figure shows the basic connection topology for PROFIBUS via M12 plug
connectors:
• For the PROFIBUS connection, the ABOXes have M12 plug connectors. They
comply with the recommendations of PROFIBUS directive no. 2.141 "Connection
technology for PROFIBUS".
• To prevent malfunctions in the bus system due to reflections, etc., the PROFIBUS
segment must be terminated using bus terminating resistors at the first and last
stations.
• The bus terminating resistors are already installed in the MOVIFIT
®
ABOX and they
can be activated using the S1 switch.
