'Last Level' and 'Last Scene' information typically comes from the DALI64 sensor. When the
user enters the setting mode for any light group these are the values that will be displayed ini-
tially, and the user will start setting (incrementing / decrementing) from these values. If 'Last
Level' and 'LastScene' information is missing, the user setting will start from 50% and scene 1.
If the DALI64 sensor is connected to port 2, the TR80 wall module will read the 'Last Level' and
'Last Scene' directly, without any dependency on a master controller. If DALI64 sensor is con-
nected on port 1 (or a different lighting control system is employed) the master controller will
need to provide this information to the wall module.
The 'New Level' and 'New Scene' registers are used to convey user commands to the master
controller. These will normally be at an invalid value of 32767. If the user selects a new light
level or a new scene on the wall module, the relevant register will contain the newly selected
value. But as soon as it is read over Modbus, it will automatically revert to the invalid value of
32767. This scheme ensures all user commands are registered as a change-of-value and can
be acted upon by the master controller.
If a DALI64 sensor is connected to port 2, the TR80 will directly send light level or scene recall
commands to the DALI64. There is no need for the master to route values in that case.
