Object PmaData (Data)

Description:

See: PmaData - Deatiled object description

The PmaData object serves for the definition of an arbitrary number of variables of various data types in one object.

No other Pma objects can be created in this object.
This object can be created in objects: PmaRoot, PmaFolder, PmaPrototype. Multiple objects of this type can be created in such objects.
This object adds variables for calculation of the application size, which influences the basic runtime licence type/size (see: Licences for PROMOTIC runtime environment).

Count	The number of variables in the object
DdeClientEnabled	The property returns or sets the permission of the DDE client communication
EndOfTransfer()	Fires the onEndOfTransfer event
GetVarArray()	Creates an array of values from all object variables
GetVarSubArray()	Creates an array of values from object variables specified by index
Item()	Access to variables of the PmVar type of this object
ItemEx()	Access to variables of the PmVar type of this object
LoadFromString()	Assignment of data item values of the object from the String value
ReadFromSocket()	Reading the data from the server group via Ethernet (TCP/IP) by means of the sockets
ReadFromSocketEx()	It is an extension of the ReadFromSocket method
ReadFromWeb()	Reading the data from Web server in the XML format
SaveToString()	Creates a string value from data item values of the object
SetVarArray()	Assignment of values from the values array to the object variables
SetVarSubArray()	Assignment of values array
SocketClientIsReady	Detects whether the object is ready to write/read over Sockets
WebClientIsReady	Detects whether the object is ready to write/read to Web server
WriteToSocket()	Sending data from the server group via Ethernet (TCP/IP) by means of the sockets
WriteToSocketEx()	It is an extension of the WriteToSocket method
WriteToWeb()	Sending data to Web server in the XML format

AddEvent()	Registers a function into the specified event
GetOwnedByIndex()	Returns the subobject defined by its index
GetOwnedByName()	Returns reference to the subobject defined by its name
GetOwnedByType()	Returns an array of references to the subobjects
GetOwnedNum()	Returns number of subobjects in the object
GetPar()	Reading the value of the Pma object parameter (or its parents)
GetPathName()	Object name with the path to this object
GetPermission()	Returns permission of corresponding operation from object
Methods	Access to designer methods of this object
Name	Object name (without the path)
Parent	Returns reference to the parent Pma object
Pm()	Returns reference to the Pma object or to its implementation subobject
RemoveEvent()	Unregisters the function in the specified event
Root	Returns reference to the root application object PmaRoot

onEndOfTransfer	Is triggered after ending the data transfer
onItemAfterWrite	Is triggered after writing into (the change of) the value of one variable
onItemBeforeWrite	Is triggered before writing into (the change of) the value of one variable

onStart	Is triggered for each object in runtime only once at the beginning
onStop	Is triggered for each Pma object in runtime only once at the stop of the application

Object	General information about the object
Events	Definition of object events algorithms
Data	Data definition
DDE	Definition of conditions for DDE sharing the variables
Sockets	The link-up of the object to the socket group
Permissions	Object permissions
Web server	The link-up of the object to Web server

PmVar	(*Variable*) Object represents one data item of the object
Data extensions	The data extensions are PROMOTIC system components, extending the basic functionality of PmVar data items (variables). Each data extension type is used for specific purpose (e.g. limit excess alarm, OPC server or connection to the PmaComm object, trends, etc.).
