1.1 About this Manual
This Manual contains information about the function library Lenze32BitTransferDrv.lib for the Drive
PLC Developer Studio.
· The functions of the function library Lenze32BitTransferDrv.lib allow data−consistent copying
of 32−bit variables even in case of a task interrupt.
1.1.1 Conventions used in this Manual
This Manual uses the following conventions to distinguish between different types of information:
Variable identifiers
are written in italics in the explanation:
· "Use bReset..."
Tip!
Information about the conventions used for the variables of the Lenze system blocks, function blocks
and functions can be found in the appendix of the DDS online documentation "Introduction into
IEC61131−3 programming". The conventions ensure universal and uniform labelling and make reading the PLC program easier.
Lenze functions/function blocks
can be recognized by their names. They always begin with an "L_":
· "With the function L_TBConvBitsToByte..."
Program listings
are written in "Courier", keywords are printed in bold:
· " IF (ReturnValue < 0) THEN..."

2.2 L_32BitTransferDINT
2.2 L_32BitTransferDINT
Function
This function is used to copy the value of variables of type double integer" (32 bits) data−consistently
to other variables of type double integer".
· The function can be called in the main program PLC_PRG or in a user task.
· When the function is started, the tasks are inhibited to ensure a data−consistent copying
process.
· After copying has been completed, the blocked tasks will be automatically released.
· Task events coming in during copying will be processed as soon as the function has been
executed. This ensures that no start signals are lost.
Declaration
BOOL L_32BitTransferDINT (pdnSource, pdnDestination);
Transfer parameters Data type Info/possible settings
pdnSource Pointer to
double integer
pdnDestination Pointer to
double integer
Return value Data type Value/meaning
Bool Status
Address of the variable of type "double integer" to be copied
Address of the destination variable of type "double integer"
TRUE Data transfer has been completed.
Examples
In the following examples, tasks are blocked during copying and the value of the variable dnSource
is copied to the variable dnDestination.
· Calling the function in FBD:
L_32BitTransferDINT
dnSource
dnDestination
ADR
ADR
pdnSource
pdnDestination
· Calling the function in ST:
pdnSource := ADR(dnSource);
pdnDestination := ADR(dnDestination);
bTransfer := L_32BitTransferDINT(pdnSource,
pdnDestination);
