<elekdra.fieldblock_out>

Field block for outgoing track

Description

This adds a semi automatic block implementation for directional traffic. Trains leaving our station are managed by this block, traffic in the incoming direction is not supported by this block. Use <elekdra.fieldblock_in> for incoming tracks or <elekdra.fieldblock> for bidirectional traffic!
On the block wire this is compatible with field block, relais block and Tf71.

Example

This 'Bl' is the starting point of a block section. The entry signal is 'ESig', the exit signal that is locked is the start signal of any route that terminates at route target 'RT'. Behind the last turnout of the station exists a track contact identified sensor 'A42'

<elekdra.fieldblock_out>
	<name>Bl</name>
	<contact>A42</contact>
	<blockroute>false</blockroute>
	<route_target>RT</route_target>
</elekdra.fieldblock_out>

Sub tags

Tag	Description
<contact> Type: String Cardinality: once	Track contact On exit route, this triggers 'Vorblock'. This is a reference to the name of a <elekdra.sensor> or <elekdra.axle_occupy_sensor>
<signalin> Type: String Cardinality: optional [0..1]	Reference of entry signal This signal has an effect on the enabling of the track contact for inbound trains. This signal normally does not exist, but if it does - maybe because the station is equipped for bidirectional traffic but can not use this capability - it is still made sure that the entry signal can be set to GO for returning shunters without accidentally triggering a Vorblock. It is a reference to the name of a <elekdra.signal>
<route_target> Type: String Cardinality: once	Route target of open track This is a reference to the <name> of a <elekdra.target>. It is the route target element of the open track that this block is associated with. This <elekdra.target> must be configured in all <elekdra.route> as <routeable>! With this mechanism, the appropriate departure signal is found that is dependent of this block when a route is established that terminates at this route target.
<name> Type: String Cardinality: once	Identification The block instance is referenced on the user interface and by other configurations by this string.
<blockroute> Type: boolean Cardinality: once	Does the blocked field block inhibit setup of a route? Setting this to 'true' has the effect that the setup of a route can be stopped by the block if the block is not in the state that permits sending trains. Setting this to true might be prototypical for some older plants, but it is not desireable for efficient operation. Setting this to false also helps to establish a route without a green exit signal but than to switch on the substitutaion signal.
