Operating modes
Description
Note
INI
Initialize
Initializes the destination range with a
byte value that is stored at the source
address. The length of the source range
is fixed at one byte. NO defines the length
of the destination range.
CPY
Copy
Copies a data block from a source to a
destination range. NO defines the size of
the data block to be copied.
Copy mode, operating mode = CPY
In Copy mode, the function block copies the complete data range of the size specified at
NO from the source range to the destination range. You specify the start of the source
range and the destination range via I1 (source address) and I2 (destination address).
Example transfer with offset
Copying a marker data block (2 bytes) with a variable offset definition for the marker
ranges.
The content of the marker bytes MB14 + MB15 are to be copied with a variable offset
that is defined via the output QV of counter relay C3.
I1
NU14
I2
C 3
NO
NU 2
Initialization mode, operating mode = INI
In initialization mode, the function block takes a byte value that is stored at the source
address (input I1) and copies it to a destination range. The destination range is specified
