Introduction

From firmware version 5.0, The Hidra Crono controller has an optional PLC feature (Programmable
logiccontroller)toallowtheimplementationofspecialfunctionsinafastandeasyway.
Withthisnewfunctionalityitis possibletoprovide theliftofpracticallyanyspecificfunctionofthe
buildingwithoutthe
needtoaddexternalelements,spendtimeaddingadditionalwiringorexternal
elementsofcontrol
Thissoftwaremoduleisdesignedtonotaffectthenormaloperationofthelift.Becauseofthis,itis
not possible to change specific functions of this. Below are indicated some examples of the
possibilitiesoffered
bythePLCmodule.

Inputs
Theinputsmaybephysicalinputs,liftstatus,temporalregistersorpermanentregisters.
ThephysicalinputsarelocatedinanyofthegeneralpurposeinputsoftheHidraCronocontroller(6
oncontroller, 6oncartop,2oneachlandingmodule,8onthepitmoduleand64
onMEXexpansion
modules). A free potential contact is required for this type of inputs, for example key switches,
pushbuttonsorrelaycontacts.
TheLiftstatusinputsaregeneratedbyHidra Cronocontrollerdependingofitsstatus,forexample,if
isdefinedaninputof“inspection” thevalueofthisinput
willbe1whiletheliftisunderinspection.
AnInputoftemporalregisterisaninternalmemorypositionusedtonestvariouselements.Thistype
ofregistersdoesnotmaintaintheirvaluesafterapowerfail.Anexampleoftheuseofthisregisters
isgivenbelow.
Aninput
ofpermanentregisterisaninternalmemorypositionasmentionedbeforebut inthiscase,
itsvalueismaintainedduringapowerfail
Outputs
TheOutputsmaybephysicaloutputs,temporalregisters,permanentregistersorliftfunctions
Asinthecaseoftheinputs,thephysicaloutputsarelocatedonanyofthegeneralpurpos eoutputs

OnMEXexpansion modulesarefreepotentialoutputs(250VAC5Amax)
An output of temporal register is an internal memory position used to nest various elements.
 This
type of registers does not maintain their values after a power fail. An example of the use of this
