Point Control Logic (CANPOINT)

A Raspberry Pi Pico based module specifically intended to handle the operation of points and the corresponding control panel on Roxeter.

Configuration

This will need to be set up in the configuration data in the code:

• Layout point number – integer
• Internal point number – integer

Consumed Events

• Roxeter panel point switch normal – on / off
• Roxeter panel point switch reverse – on / off
• Route requiring points normal called (on) / cleared (off) - High Byte TBC
• Route requiring points reverse called (on) / cleared (off) - High Byte TBC
• Points detected normal – on / off
• Points detected reverse – on / off
• Track(s) over points occupied (on) / clear (off)

Produced Events

• Point motor movement request reverse (on) / normal (off) - High byte 0
• Points normal indication – on / off - High byte 1
• Points reverse indication – on / off - High byte 2
• Points locked indication – on / off - High byte 3
• Points out-of-correspondence indication – on (flashing) / off - High byte 4
• Points set and locked normal – on - High byte 5
• Points set and locked reverse - on - High byte 6

Internal State

Point state:

• Unknown
• Normal
• Locked normal
• Reverse
• Locked reverse

Availability:

• Free to be locked normal
• Free to be locked reverse

Some events are predefined and cannot be changed. All have the CANPOINT's node number with the event number set as follows:

• 1 - the CANPOINT's node number with the event number set to the internal point number plus 1000,
• 2 - the CANPOINT's node number with the event number set to the internal point number plus 2000.
