module functions

The Trainnet® CPE is a straightforward processing unit designed exclusively for Ethernet bus connectivity. It is used exclusively as a part of the Trainnet® Remote Input/Output Module (RIOM) to redirect I/O signals between the train computer (e.g. VCU) and the RIOM.

key features

The Trainnet® CPE comes with a 10/100 Mbit/s Full Duplex Ethernet interface that is used to connect to the Trainnet® train computer.

The Trainnet® CPE simply reads and writes I/O signals. It is able to redirect input signals from the RIOM to the train computer. The CPE can also get information from the train computer and pass it on to the RIOM I/O modules that generate output signals.

Please note that the CPE does not have a real-time clock or flash memory: it cannot be used to run train applications. It works only when it is connected to a Trainnet® train computer, typically a Gateway, VCU or TCMS.
