Instruction Usage Properties
MOVE Copy value
 Copies the content of the parameter at
the IN input to the parameter of the
OUT output.
 The parameters at the input and output
must be of the same data type.
 The parameters can also be structured
tags (PLC data types).
MOVE_BLK Copy array
 Copies the content of an array to
another array.
 The source and target array must be of
the same data type.
UMOVE_BLK Copy array
without
interruption
 Copies the content of an array without
any interruption to another array.
 The source and target array must be of
the same data type.
MOVE_BLK_VARIANT Copy array
 Copies one or several structured tag(s)
(PLC data types).
 Recognizes data types at runtime.
 Supplies detailed error information.
 Apart from the elementary and
structured data types, also PLC data
types, arrays, and array DBs are
supported
Note
UMOVE_BLK: The copy process cannot be interrupted by another activity of the
operating system. Therefore, the alarm reaction times of the CPU might increase
during processing of the instruction "Copy array without interruption".
For the complete description of the MOVE instructions, please refer to the TIA
Portal Online Help.
2.9.3 RUNTIME
Using the "RUNTIME" instruction you measure the runtime of the complete
program, single blocks or the command sequences. You can call this instruction in
SCL (S7-1200/S7-1500) and in STL (S7-1500).
NOTE
You will find further information in the following entry:
With S7-1200/S7-1500, how do you measure the time of a program section or
the complete program cycle at runtime?
