Using the Lua Script

To use the Lua script, create a file at the path specified in the configuration. It will be executed every X seconds (where X is set in the configuration under trigger).

Example Lua script:

local modbus = require("modbus1")      -- load the modbus module with configuration modbus1

local data = modbus.readHoldingRegisters(0, 10, "uint32") -- read registers 0-10 as uint32 (automatically split per the specified type)

for i, v in ipairs(data) do
    print(i, v)
end

Refer to the modules documentation for more details.
