Hello,
After following the IoT Connectivity with Thingworx course, I'd like to understand if is it possible to use on handler for more than one properties.
For Example:
I'd like to update signal1, signal2 and signal3 values 0 or 1, but it doesn't seem to work for me.
SolarCollector1.lua:
properties.Signal1 = { baseType=“NUMBER”, pushType=“NEVER”, value=1, handler=“signalhandler” }
properties.Signal2 = { baseType=“NUMBER”, pushType=“NEVER”, value=1, handler=“signalhandler” }
properties.Signal3 = { baseType=“NUMBER”, pushType=“NEVER”, value=1, handler=“signalhandler” }
signalhandler.lua:
function read(me, pt, headers, query)
log.info(p_data.name, “Entering Signal Read Handler Function”)
– use csvtools to get last line
csvtools = require(“csvtools”)
file = io.open(“c:\EMS\microsever\logs\signal_log.csv”)
local lastline = csvtools.getLastLine(file)
local signalName = pt.name --For example Signal1
local rightColumn = 0
csvtable = csvtools.csvfile2table(file)
for k,v in ipairs(csvtable) do
for k2,v2 in ipairs(v) do
if v == signalName then
rightColumn = k
end
end
end
local timestamp = tonumber(lastline[1])
pt.value = tonumber(lastline[rightcolumn]
pt.time = tostring(os.time())
pt.quality = “GOOD”
pt.next = nil
tw_mutex.unlock()
return 200
end
