-- ======================
-- Description
-- ======================
--
-- Umożliwia załączenie lub wyłączenie wyjścia na podstawie wejścia z niezależną zwłoką na załączenia lub wyłączenia wyjścia.
-- Przy czym załączenie oznacza wartość <> 0 a wyłączenie oznacza wartość 0
-- Osobna zwłoka dla załączenia lub wyłączenia.
--
-- Jeżeli podczas fazy wyłączenia input zmieni stan na <> 0 to następuje przerwanie fazy wyłączania i output = input.
--
-- Jeżeli w fazie załączania input zmieni stan na 0 to następuje przerwanie fazy załączania i output = 0.
--
-- ======================
-- Parameters
-- ======================
--
-- SubLogic supports following variables:
--
-- input.value - wejście
--
-- output - wyjście
--
-- counter.main.downcounter - licznik który odlicza czas do 0.
--
-- counter.cnt.downcounter - podlicznik, po osiągnięciu wartości 0 wartość counter.main.downcounter jest zmniejszana o 1
--
-- counter.phase - faza opóźnienia
-- 0 - brak zwłoki (output = input)
-- 1 - faza zwłoki w załączeniu (output = 0) do czasu upłynięcia licznika counter.main.downcounter
-- 2 - faza zwłoki w wyłączeniu (output = input) do czasu upłynięcia licznika counter.main.downcounter
--
-- setting.on.delay - zwłoka w załączeniu wyjście (przejścia z output o wartości 0 do wartości input)
--
-- setting.off.delay - zwłoka w wyłączeniu wyjście (przejścia z output o wartości <>0 do wartości 0)
--
-- setting.cnt.period.on.delay
-- setting.cnt.period.off.delay - okres w sekundach podlicznika do zmniejszania licznika głównego counter.main.downcounter.
-- w zależności od tego czy jest liczona zwłoka w załączeniu czy wyłączeniu wyjścia Np.
-- 60 oznacza odliczanie czasu (counter.work_time) w minutach.
-- 3600 oznacza odliczanie czasu w godzinach.
--
-- Logic uses lua language to implement own behaviour
--
-- ======================
-- mandatory variables
-- ======================
--
-- Logic expects following mandatory variables:
--
-- reload.trigger - causes reloading lua script
--
-- memcnt - current amount of memory used by lua in bytes
--
-- Logic expects following kv settings:
--
-- LuaScriptPath - path to the lua script - must be absolute
--
-- ======================
-- ChangeLog
-- ======================
--
-- 2020-04-06 ver 1.0.0
--
-- + First release
--
-- user can use some functions provided by ibmanager.
-- ibmanager provides following functions to use:
--
-- function returns value of required ibmanager variable
-- @param fullName - string - variable name - name of variable of which value must be returned, for example "rs.0.id.255.input.t.0.value"
-- @return - string or integer - variable value or "nil" if variable not exist or is not readable
--
-- getValue(fullName)
-- function set value of given ibmanager variable
-- @param fullName - string - variable name - name of variable of which value we want to set, for example "rs.0.id.255.input.t.0.value"
-- @param value - string, int or boolean - value to set
-- @return - nothing
--
-- setValue(fullName, value)
-- function returns value of required ibmanager variable
-- @param key - placed in xml logic configuration file:
-- * as attribute: Name, in Var, RemoteVar and ImportVar elements in the case of stand alone variables
-- * as concatenation of two attributes: ListName.Postfix in VarListItem, RemoteVarListItem and ImportVarListItem elements
-- in the case of variables that are placed in lists
-- @return - string or integer - variable value or "nil" if variable not exist or is not readable
--
-- getLogicValue(key)
-- function set value of given ibmanager variable
-- @param key - placed in xml logic configuration file:
-- * as attribute: Name, in Var, RemoteVar and ImportVar elements in the case of stand alone variables
-- * as concatenation of two attributes: ListName.Postfix in VarListItem, RemoteVarListItem and ImportVarListItem elements
-- in the case of variables that are placed in lists
-- @param value - string, int or boolean - value to set
-- @return - nothing
--
-- setLogicValue(key, value)
-- function returns two sections of kvsettings from xml configuration file
-- returned value is two element table, each of these elements is table too.
-- indices of returned table are strings and equal "instance" and "global"
-- values of returned tables are tables and contain KVsettings for applicable section.
-- nested tables have form key = value, where key is index in nested table and value is value.
-- example: {"instance" = {"ikey1" = "ivalue1", "ikey2" = "gvalue2"}, "global" = {"gkey1" = "gvalue1", "gkey2" = "gvalue2", "gkey3" = "gvalue3"}}
-- @return - two dimensional array - kvsettings for global and instance sections
-- getKvSettings()
-- function schedules alert to send.
-- rules are defined in separated alert configuration files and are described in ibmanager instruction manual
-- @param id - alert identifier - must be defined in current logic configuration file in section: <Alert Id="any_identifier" ...
-- scheduleAlert(id)
-- function cancels alert sending, if was previously scheduled. if not then only wakes up alerts handling thread, so if there is no need to call this function, then do not call it.
-- rules are defined in separated alert configuration files and are described in ibmanager instruction manual
-- @param id - alert identifier - must be defined in current logic configuration file in section: <Alert Id="any_identifier" ...
-- cancelAlert(name)
-- function returns table, containing Variables that belongs to required list.
-- @param listName - Name attribute of VarList, RemoteVarList or ImportVarList elemetnst in configurationfile
-- @return array of key-value pairs. Key - variable postfix, Value - Variable value
-- getVarList(listName)
-- function returns monotonic system clock value, that elapsed since specific epoch
-- returned time is expressed in milliseconds.
-- getClock()
-- function logs message to file, if defined in configuration file log level is less than passed to this function
-- @param logLevel - one of:
-- LogLevel.TraceLo
-- LogLevel.Trace
-- LogLevel.TraceHi
-- LogLevel.DebugLo
-- LogLevel.Debug
-- LogLevel.DebugHi
-- LogLevel.Info
-- LogLevel.Notice
-- LogLevel.Warning
-- LogLevel.Error
-- LogLevel.Critical
-- @param logMessage - string to log
-- log(logLevel, logMessage)
-- ibmanager provides following global variables:
