TCM’s build-in real time data acquisition system enables processing of raw field data acquired and transmitted directly from TCM field PLCs located in the Train Control Rooms (TCR) to the central TCM server. This eliminates latency, dependency on other subsystems and increases reliability.
Typical Integration of TCM into an Agency’s Systems Infrastructure
Lightning fast response times via modern industrial protocol – OPC UA
OPC UA (short for Open Platform Communications United Architecture) is a data exchange standard for industrial communication. TCM is based on OPC UA for communication between the central server and wayside field PLCs.
Small is Beautiful
Highly modular microPLC products like the Simatic S7-1200 PLC series from Siemens allow for highly customizable and cost effective solutions
