Object PmData (Data)

Description:
See: PmData - Deatiled object description
 
The PmData object serves for the definition of an arbitrary number of variables of various data types in one object.
 
No other PROMOTIC objects can be created in this object. This object can be created in the PmRoot, PmFolder and PmPrototype objects. Multiple objects of this type can be created in such objects.

This object adds variables into the calculation of the application size, which influences the basic runtime license type/size (see: Price list of PROMOTIC system ).

This object adopts properties and methods of object PmObject
Properties and methods:
Count Number of variables in the object
DdeClientEnabled Setting/getting the permission of the DDE client communication
EndOfTransfer Fires the onEndOfTransfer event
GetVarArray Create array of values from all object variables
GetVarSubArray Create array of values from object variables specified by index (from-to)
Item Access to variables of type Var of this object
ItemEx Access to variables of type Var of this object
LoadFromString Assignment of data item values of object from the String value
ReadFromSocket Reading data from the server group over the TCP/IP using the sockets
ReadFromSocketEx It is an extension of the ReadFromSocket method
ReadFromWeb Reading data from WEB server in the XML format
SaveToString Creating 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 Finding out it the object is ready to write/read over Sockets
WebClientIsReady Finding out it the object is ready to write/read to WEB
WriteToSocket Writing data to the server group over the TCP/IP using the sockets
WriteToSocketEx It is an extension of the WriteToSocket method
WriteToWeb Writing data to WEB server in the XML format
Events:
onEndOfTransfer Fires after ending the data transfer
onItemAfterWrite Fires after writing into (the change of) the value of one variable
onItemBeforeWrite Fires before writing into (the change of) the value of one variable
Configuration windows:
Object General information about the object
Content Content of the object in the XML form
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 the WEB server
List of subobjects:
Var(Variable) This object represents one data item of the object
Data extensions The data extensins are PROMOTIC system components, extending the basic functionality of Var data items (variables). Each data extension type is used for specific purpose (e.g. limit excess alarming, OPC server or PmComm object connection, trends, etc.).
