Controller for railway applications

Moxa’s ioPAC 8600 modular programmable controller combines various interfaces into a single device. It is particularly suited for railway applications.

The controller supports the C/C++ and IEC 61131-3 programming languages and ready-to-run services, including CANopen (CiA 301), data logging, Modbus TCP master/slave, active tag to OPC, and SNMP V1/V2c/V3. Packing all of these features into one product aims to sustain system reliability, seamless data transmission, and simplified deployment and maintenance.

A refurbished train may only have a limited number of coupler poles, even when the entire existing network, which could include wiring for CAN, EIA-485, and other technologies, is removed. Moxa’s two-wire Ethernet technology offers system integrators the option to upgrade to an IP network using existing wiring.

The solution provides more options for train communication network refurbishment projects. One module can be used to create a 100 Mbit/s Ethernet backbone using existing cabling, and supports by-pass functionality. However, if users are looking for more bandwidth plus redundancy, they can use the modules in pairs.

Older train systems run on a daisy-chain network topology based on either CAN or EIA-485. When it comes time to switch to an IP-based network on the refurbished train, duplicating the automatic carriage sequencing function is not easy. Moxa gets around this challenge by building support for automatic carriage sequencing functions directly into the IP network, reducing the effort required by the system integrator.

At the Innotrans 2016, Moxa will show the controller at their booth 4.1/320. The exhibition will take place from September 20 to September 23 in Berlin, Germany.
