Get object name

Event script (attached to a tag):

Code:

value = event.getvalue() name = grp.find(event.dst).name now = os.time() h_key = 'h_alarm' l_key = 'l_alarm' h_lim_obj  = string.gsub(name, '_PV', '_HAL') l_lim_obj  = string.gsub(name, '_PV', '_LAL') alarm_h_obj = string.gsub(name, '_PV', '_AHL') alarm_l_obj = string.gsub(name, '_PV', '_ALL') h_alarm = value > grp.getvalue(h_lim_obj) l_alarm = value < grp.getvalue(l_lim_obj) if h_alarm then   storage.exec('hsetnx', h_key, name, now) else   storage.exec('hdel', h_key, name)   grp.checkwrite(alarm_h_obj, false) end if l_alarm then   storage.exec('hsetnx', l_key, name, now) else   storage.exec('hdel', l_key, name)   grp.checkwrite(alarm_l_obj, false) end

Resident script. Adjust the sleep time as needed (at least 5 seconds) depending on the average delay between objects value being detected as out of bounds and the alarm object change to 1.

Code:

if not check then   storage.openconn()   check = function(storage_key, alarm_obj_key)     local now = os.time()     local items = storage.exec('hgetall', storage_key)     for name, time in pairs(items) do       local delay_obj = string.gsub(name, '_PV', '_AD')       time = time + grp.getvalue(delay_obj)       if now >= time then         local alarm_obj = string.gsub(name, '_PV', alarm_obj_key)         grp.checkwrite(alarm_obj, true)       end     end   end end check('h_alarm', '_AHL') check('l_alarm', '_ALL')
