EKM1101 | EtherCAT Coupler with ID switch and diagnostics
The EKM1101 EtherCAT Coupler connects the ELMxxxx EtherCAT measurement modules with EtherCAT. Such a station consists of an EKM1101 coupler, any number of EtherCAT Terminals and a bus end cap or an EtherCAT extension such as EK1110 or EK1122. The coupler converts the passing telegrams from Ethernet 100BASE-TX to E-bus signal representation.
On account of three significant properties, the EKM1101 and the functionally identical ELM9410 power supply terminal are designed to meet the needs of high-precision analog measurement technology, e.g. with ELM3xxx terminals:
- To reduce interference in the connected terminal, both the E-bus supply US and the 24 V power contact supply UP are electrically isolated and filtered in the coupler. The power contact supply can carry a maximum load of 2 A.
- The extensive voltage and temperature monitoring provides assistance with commissioning and operation; results are displayed by LED and in the process image.
- The built-in three-axis position and vibration sensor allows a constant view of the mechanical situation in the control cabinet.
As a result, the EKM1101 can be used in special measuring situations instead of the conventional EK1100 EtherCAT Coupler. Mixed operation with EL9410 is possible, but this negates the concept of electrical isolation. The EKM1101 has two hexadecimal ID switches for assigning an ID to a group of EtherCAT components. This group can then be located at any position within the EtherCAT network. Variable topologies are therefore easily implementable.
