Pattern collection pro

Once you have built many plants you notice: they are the same shapes again and again. A pro does not write them anew every time but recognises them as building blocks and puts them together.

Four building blocks of the pro level#

Tracking always has the same form, whether panels, lights or valves follow:

lbn target SENSOR HASH("Sonne") Horizontal Average
jal convert                # to suit the build
select target night PARK target   # park at night
sb PANEL Horizontal target

The conversion depends on how you built it – for solar panels you know it from day 186. At night a select sends the devices into a parking position.

One block for three controls#

Generator, load shedding and target quantity look different but are the same hysteresis: “on below the lower limit, off from the upper one”. With load shedding only the output is inverted – shedding happens below the limit, the light is the opposite of that.

So you write the hysteresis once as a subroutine. Before each call you set four registers:

move value level
move low GEN_ON
move high GEN_OFF
move state gen
jal hyst
move gen state

The previous state of each control stays in a register of its own (gen, shed, furn). The subroutine only works on state.

Combining blocks#

A collective alarm connects blocks that know nothing about each other: batteries missing, store missing. Each condition becomes 0 or 1, or combines them. In addition each control gets its own safe direction: without a battery value the generator runs, without a store the furnace stands still.
