Safety PLC for rolling stock
Safety PLC for rolling stock
More reliability and safety
The requirements for rail vehicles of today and tomorrow grow constantly. Faster and faster connections must be made while maintaining a high passenger comfort. This is why, in their daily use, trains are subjected to very high stress, related to Environ-mentironmental, electrical and mechanical factors. This calls for higher and higher regulatory standards for rail vehicles.
ABB helps satisfy the high expectations towards the safety of the vehicles
ABB delivers reliable components, solutions and systems for rolling stock, always complying with the current standard requirements. Among others, these include:
− Safety Controller Pluto D20 Harsh Environment − Safety Controller Pluto D45 Harsh Environment
Using equipment on trains — what must
be taken into account
Rail vehicles must be specially equipped to be reliable within their respective areas and conditions of use. Examples of such areas and conditions include, among other things, the trains being primarily used in tunnels, or used at high speeds, or used as night trains with sleeping coaches. In providing trains with equipment, particular attention must be paid so the service life of the equipment is not shorter than the service interval of the rail vehicle. Further-more, the safety of passengers must be guaranteed, so that in the event of an emergency no additional hazard is created by defective electric equipment —an important aspect— especially if escape routes are limited, e.g. in tunnel systems.
ABB is a leading global independent supplier of innovative and reliable technology for rolling stock, railway operators and railway infrastructure operators. Using its all-encompassing business experience in energy and automation technology, ABB can offer reliable and cost-effective solutions for both these fields.
General standards for railway use
Fire protection and general electrotechnical requirements
Continous operation — in the most
extreme of conditions
Always on the move, despite heat, cold and humidity: the Environ-mentironmental conditions in which rail vehicles are used are gener-ally far more extreme than in an industrial plant. Their electronic components must correspondingly be completely vibration-proof, resistant to cold, dry and humid heat, and the resulting condensed water. Furthermore, as well as their electromagnetic compatibility, these devices must meet particularly high fire safety requirements. In the event of a fire, danger to people comes not only from the flames, but also from the smoke and poisonous vapors. Complete reliability under extreme conditions as well as a high degree of safety must be guaranteed. Nothing can be left to chance. All the components of a rail vehicle undergo numerous load tests before they are commissioned. Everything is tested and documented on the basis of safety standards and specifications.
The standards for electronic equipment used in and on rail vehicles – EN 50155 and IEC 60571
EN 50155 is the most important standard for electronic equipment used in and on rail vehicles. With the exception of local fire and smoke protection standards, this standard acts as an umbrella standard encompassing all the important electric and mechanical aspects. These include:
− the temperature according to EN 50125 − the humidity according to EN 50125 − the voltage supply according to EN 50155 − the insulation coordination according to EN 50124 − the electromagnetic compliance according to EN 50121 − the shock and vibration resistance according to EN 61373
The fire and smoke protection standard EN 45545
EN 45545-1 provides a classification of risks according to the categories of operation and design of train. The design of trains include four very different types of trains, e.g. standard vehicles and special trains with sleeping coaches. These trains can be operated in different categories. According to EN 45545-1, there are four such categories that depend on how many kilometers a route may lead through a tunnel or elevated section. A combination of these two criteria is decisive in classifying the hazard levels. A stan-dard vehicle that drives through a tunnel for less than a kilometer is classified as HL1. Below you will find a table that shows the hazard level that depends on the combination of the operation categories and the design categories.
Design categories
N A D S
Standard
vehicle Automated train without emergency trained crew Double decked vehicle Sleeping coach, 2-level or 1-level Operation categories 1 Tunnel < 1 km HL1 HL1 HL1 HL2 2 Tunnel < 5 km HL2 HL2 HL2 HL2 3 Tunnel > 5 km HL2 HL2 HL2 HL3
4 Train without side evacuation HL3 HL3 HL3 HL3
The Harsh Environment versions of Pluto safety PLC can be used on all trains up to hazard level HL3. The main criteria specified by EN 45545 include, among others, the oxygen index, which must be above 32%. For the Harsh Environment Plutos, this condition is met. Another critical aspect is the production of smoke, as well as the transparency and toxicity of the smoke. In the event of a fire, an opacity value of 150 guarantees that the smoke does not completely block the sight and the passengers can still orient themselves in the train.

IDFIX-PROG 10k (2TLA020070R2600)
Pluto is a safety PLC concept with the All-Master key feature, which simplifies safety system design and complies with the highest safety level, PL e, according to EN ISO 13849-1 and SIL 3 according to EN 62061, IEC/EN 61508. It also complies with all the relevant parts of EN 50155.
Pluto is an All-Master system for dynamic and static safety circuits, in which the inputs and other data are distributed via the same bus. One input can be used to connect several safety sen-sors, while maintaining the highest safety level. Pluto offers inputs for every safety product on the market. The function of the inputs is defined via the Pluto Manager software that is supplied with the equipment. Apart from failsafe inputs (I), Pluto offers several failsafe relay and transistor outputs (Q).
On every Pluto, even more failsafe inputs, non-failsafe outputs or simultaneous input/outputs (IQ) be set up. The features are provided in a simple way in Pluto Manager. Up to 32 Plutos can be connected to the same Pluto bus, making Pluto able to man-age both small and large safety systems. As Pluto is an All-Master system, each Pluto unit can control its own outputs locally and read the inputs of other Pluto units as easily as its own. Gateways on the Pluto bus allow for data exchange with other systems.
Pluto D20 and D45 with analog inputs
Pluto D20 is equipped with 4, and Pluto D45 with 8 safe analog inputs (4—20 mA/0—10 V). These can be configured as either ordinary failsafe inputs or as analog inputs (0—10 V or 4—20 mA).
Counter inputs Pluto D45
In Pluto D45, four of its analog inputs can be configuredas counter inputs (pulse counting) for frequencies of up to 14,000 Hz. The counter inputs IA0—IA3 can be used in two ways (counting forwards or forwards/backwards).
IDFIX-PROG
With IDFIX-PROG 2k5 or 10k it is possible to save entire projects. IDFIX-PROG is an additional component for the Pluto safety PLC used primarily for models without safety bus. It makes sure that the program can be easily recovered, in case the Pluto should need to be replaced. This means that no laptop is required when replacing units on the rail vehicle, which can lower downtimes to a minimum.
