2.3.19.4 Connection of EtherCAT-Coupler of type EK1501 for fibre optic cable
If the analog sensor signals should not be connected on the central Peakanalyzer, they can
be connected on a distributed station in a separate steel box in the field. The subsystem than
has to be connected via fibre optic cable to the central Peakanalyzer base module.
The Coupler EK1501 is used for the Ethernet signal transmission in the EtherCAT network.
Picture 18: View of EtherCAT-Coupler of type EK1501 for fibre optic cable
The EtherCAT-Coupler EK1501 connects the branched Peakanalyzer terminals of type
ELXXXX in a separate steel box with the central Peakanalyzer base module via fibre optic
cable.
Such a Peakanalyzer station consists of the Coupler of type EK1501, a number of EtherCAT
terminals, a bus end cap and a power supply. The coupler transforms the telegrams of the
Ethernet-100Base-FX to the E-Bus signal representation.
The SC-Duplex connector of the fibre optic cable from the central Peakanalyzer base station
is connected to the upper EtherCAT input X1. The fibre optic cable must have the same unique
identification label as the coupler input IN.
The SC-Duplex output X2 can be optionally used to connect a further branched Peakanalyzer
station. The outgoing EtherCAT branch from port X2 must be labeled on the coupler and the
corresponding fibre optic cable. Chapter 2.3.19 describes in more detail the labeling schema
of the unique identifier for junction, coupler and cable.
For better understanding an example for the labeling:
The first coupler of type EK1501 of the first Peakanalyzer as well as the corresponding junction
port X1 and the fibre optic cable have the label 1.1.
The second coupler of type EK1501 of the second Peakanalyzer as well as the corresponding
junction port X1 and the fibre optic cable have the label 2.2.
The clamp labeled with X5 is the power supply for the coupler and has to be connected as
described in chapter 2.3.1, 2.3.2 and 2.3.13.
