CANx based meter counter

[admin]

You can use binary input mode and event script to measure the time between each ON telegram.

Code:

value = event.getvalue()
if not value then
  return
end

tsec, tusec = os.microtime()
time = tsec + tusec / 1000000

key = 'on_time'
out = '1/1/2'

delta = time - storage.get(key, 0)
  
log(delta)

if delta < 0.4 then
  grp.checkwrite(out, false)
elseif delta < 0.8 then
  grp.checkwrite(out, true)
end

storage.set(key, time)
