Those which are off --- would require no or a small standby EU demand, while those which are on would --- require more. --- If the total demand is less than the available power they are all updated with the --- demand number. --- If any surplus exists from the PR nodes the batteries will be charged evenly with this. --- If the total demand requires draw on the batteries they will be discharged evenly. --- --- If the total demand is more than the available power all RE nodes will be shut down. --- We have a brown-out situation. --- --- Hence all the power distribution logic resides in this single node. --- --- Nodes connected to the network will have one or more of these parameters as meta data: --- <LV|MV|HV>_EU_supply : Exists for PR and BA node types. This is the EU value supplied by the node. Output --- <LV|MV|HV>_EU_demand : Exists for RE and BA node types. This is the EU value the node requires to run. Output --- <LV|MV|HV>_EU_input : Exists for RE and BA node types. This is the actual EU value the network can give the node. Input --- --- The reason the LV|MV|HV type is prepended toe meta data is because some machine could require several supplies to work. --- This way the supplies are separated per network. +-- See also technic/doc/api.md technic.networks = {} technic.cables = {} +technic.redundant_warn = {} + +local mesecons_path = minetest.get_modpath("mesecons") +local digilines_path = minetest.get_modpath("digilines") local S = technic.getter + +local cable_entry = "^technic_cable_connection_overlay.png" minetest.register_craft({ output = "technic:switching_station", @@ -45,11 +20,22 @@ } }) +local mesecon_def +if mesecons_path then + mesecon_def = {effector = { + rules = mesecon.rules.default, + }} +end + minetest.register_node("technic:switching_station",{ description = S("Switching Station"), -
