In this application, a DIN rail based OEM control system is used for centralized or decentralized control, monitoring and diagnosis of all functions during drive and brake operation. The system optimizes the operation process and relieves the driver. Theopen modular system is based on a standardized IEC 61131 user interface and modular hardware using a safe CANopen protocol as the system bus. It works in an ambient operation temperature between -40 to +85°C and the electronic boards inside are conformalcoated to protect them from condensation. The housing is HF-tight and resistant to solvents.
The individual modules feature plug-and-play functionality and can be hot-plugged during operation. All of them have their own self-diagnosis. Continuous tests during operation allow for error recognition independent of the switch state. The system conforms to the EN 50155 railway standard, with safety standard according to EN 50126, 50128, 50129 and protection level IP40. The processor module is based on theMPC5200 PowerPC and features Ethernet, USB, UART and CAN bus interfaces and an alphanumeric display for status and diagnosis. The power supply covers wide range inputs from 24 to 110V, is short-circuit proof and comes with continuous, no foldback, inrushcurrent limiting.
The collection of I/O modules includes digital input and output modules with 8 to 155 V wide range I/O, analog input and output modules with each channel individually electrically isolated, relay, PT100 and pulse encoder input modules.The bus system support comprises CAN bus, Ethernet, optionally MVB as the wagon bus and WTB via gateway as connection to the train bus.
A similar train control application uses CompactPCI systems with 3U cards in a conductive cooling enclosure for driverless, remote control of locomotives. The PowerPC based CPU card is equipped with an MPC8548.
