SPECIAL SVs - LIGHT SIGNAL

This Chapter describes the Usage of the SV Configuration Variables, which are espacially used for Light Signals.

Each SV defines the pins for one of the eight elements. The "S" Bits of the register define the Start Pin of the element and the "N" Bits of the same SV defines the count of pins used for the same element. The Number of Pins is the Value of N13...N10, which is minimum 0 and maximum 8. (Maximum of 8 Pins per Element)

e.g. If N is 3, the Element uses 3 Pins, starting at Pin 0 (If "S" is 0).
So the element uses Pin 0, Pin 1 and Pin 2.

If "N" is 0, the element is disabled and does not write to any pin.

113 SPECIAL PIN BYTE, Element 4 RW

117 SPECIAL PIN BYTE, Element 8 RW

7 6 5 4 3 2 1 0

D3 D2 D1 D0 E3 E2 E1 E0

The "D" Bits of the register define the Pin Number of an Departure Signal (Abfahrtsignal) of Element 1 to Element 8.
The "S" Bits of the register define the Pin Number of an Substitution Signal (Ersatzsignal) of Element 1 to Element 8.

e.g. If D is 2, the Element uses Pin 2 for the Departure Signal.

118 SUBSTITUTION BLINK BYTE RW

7 6 5 4 3 2 1 0

SB8 SB7 SB6 SB5 SB4 SB3 SB2 SB1

The "SB" Bits define, if the corresponding Substitution Signal of the Element (1 to 8) is blinking (1) or not (0).

e.g. If SB2 is 1, The Substitution Signal of Element 2 is blinking.

119 DEPARTURE BLINK BYTE RW

7 6 5 4 3 2 1 0

DB8 DB7 DB6 DB5 DB4 DB3 DB2 DB1

The "DB" Bits define, if the corresponding Departure Signal of the Element (1 to 8) is blinking (1) or not (0).

e.g. If DB3 is 1, The Departure Signal of Element 3 is blinking.

SIGNAL MAPPING

For each element and each state, a defined aspect can be defined. Here the connection between the State and the aspect is built.

120 + SIGNAL STATE Signal Mapping, Element 1 RW

155 + SIGNAL STATE Signal Mapping, Element 2 RW

190 + SIGNAL STATE Signal Mapping, Element 3 RW

225 + SIGNAL STATE Signal Mapping, Element 4 RW

260 + SIGNAL STATE Signal Mapping, Element 5 RW

295 + SIGNAL STATE Signal Mapping, Element 6 RW

330 + SIGNAL STATE Signal Mapping, Element 7 RW

365 + SIGNAL STATE Signal Mapping, Element 8 RW

The value of the SV register ist the index of the predefined signal layout.

e.g. If SV 304 is 4, Element 1 mapps the predefined Signal 4 (SV 204 and SV 254) to the according output pins.

SIGNAL ASPECTS

You have the possibility to define 50 different Signal Aspects with 8 Pins per State (maximum Number of Pins per Element). The Element can map these Pinmap to each signal state. The Pinmap starts at the startbit and is copied to the pins. If the Elements uses less than the 8 possible bit, only the number of used pins are copied, started at Bit 0.

400 - 449 PIN MAP, Signal 0 to Signal 49 RW

450 - 499 BLINK MAP, Signal 0 to Signal 49 RW

If the according Pin in the Blink Register is set to 1, the Pin is blinking.

136 Go, Vmax = 100km/h 0

137 Go, Vmax = 110km/h 0

138 Go, Vmax = 120km/h 0

139 Stop at Shunting Signal ( use 0 instead!) 0

140 Go at Shunting Signal 0

141 Signal Dead 0

142 Signal Dead, Zs1 0

151 "Kennlicht" 0

As the signal does not support all states, the unused states will show an "Stop" aspect.
