EMS question about connect
A script written via Lua does not change the value
How do I get it updated at regular intervals?
After luaScriptResourse is executed in cmd, update the value only once at the first time.
module ("templates.PiTemplate", thingworx.template.extend)
properties.cpu_temperature = { baseType="NUMBER", pushType="ALWAYS", value=0 }
properties.cpu_freq = { baseType="NUMBER", pushType="ALWAYS", value=0 }
properties.cpu_volt = { baseType="NUMBER", pushType="ALWAYS", value=0 }
serviceDefinitions.GetSystemProperties(
output { baseType="BOOLEAN", description="" },
description { "updates properties" }
)
services.GetSystemProperties = function(me, headers, query, data)
log.trace("[PiTemplate]","########### in GetSystemProperties#############")
queryHardware()
-- if properties are successfully updated, return HTTP 200 code with a true service return value
return 200, true
end
function queryHardware()
local a = math.random(0,10)
local b = math.random(10,20)
local c = math.random(30,40)
properties.cpu_volt.value = a
properties.cpu_freq.value = b
properties.cpu_temperature.value = c
end
tasks.refreshProperties = function(me)
queryHardware()
end
I want to update the value regularly with a random function.
Help plz
thanks
