CPU with Serial Links
The EKE-Trainnet® Central Processing Unit with Serial Links (CPS) serves as a processor for managing train computers and connected subsystems.
The EKE-Trainnet® CPS module is a processing unit providing serial communication interfaces. It enables the development, storage, and execution of applications for controlling and diagnosing on-board systems, making it ideal for creating Train Control and Management Systems (TCMS) or Vehicle Control Units (VCU). Additionally, the CPS can function as a Gateway, offering essential interfaces and routing capabilities.
Key Features
Three programmable isolated SCC channels (RS 485), with an optional fourth channel, are available for asynchronous or bit-synchronous communication with compatible train devices.
The EKE-Trainnet® CPS real-time clock is powered by a back-up capacitor and will run for a minimum of 30 days from the time power is no longer applied.
A 10/100 Mbit/s full-duplex Ethernet interface enables connection to any Ethernet communication network, typically linking the CPS to switches or electronic racks. Alternatively, it can connect directly to Ethernet-enabled devices, such as network cameras. The number of Ethernet interfaces can be expanded by using one of the EKE-Trainnet® Ethernet Switches.
The CODESYS® PLC kernel embedded in the CPU acts as the CPU’s operating software. Train management applications can be developed with the CODESYS® PLC software in order to create the desired control and diagnostic functions of the train. The open platform runs on the Linux Operating system and supports further software development in C language, either as a CODESYS® extension or on top of the module’s Linux kernel. The PowerPC processor provides enough processing power for demanding applications with 400 MHz core speed and 64 megabytes of 64-bit wide 100 MHz SDRAM.
The EKE-Trainnet® Portable System Tester (PST) interface (usually serial link or Ethernet) enables the use of the PST as well as other tools for event log operations, maintenance, debugging, downloading and application development purposes.
Options
The EKE-Trainnet® CPF is similar to an EKE-Trainnet® CPS with an extended event logging flash memory (4 GB vs 512 MB). EKE-Trainnet® CPF can act as a low cost event recorder when limited memory and protection are required. The EKE-Trainnet® CPF has all the features of the EKE-Trainnet® CPS.
