M12 connector for the in-coming bus line
M12 connector for the outgoing bus line
4.2 Fieldbus termination
The bus is terminated using an external terminating resistor� The modules are not
capable of fieldbus termination�
The bus termination must be accomplished externally using a connector with integrated terminating
resistor (E12315) as passive terminating resistor�
4.3 Nominal current consumption of modules connected to PROFIBUS-
DP
It is important to consider the current consumption of the individual modules for
power-feed, module protection and assessment of the voltage drop on the power
cable�
Chapter 7 contains a table with the nominal current consumption of the modules�
