6. Function blocks
6.1 Manufacturer function blocks
at input I2, and the length is defined by the value at input NO. The exact same source
byte value (MB) is then copied to every single byte in the destination range.
If you select a type MD or MW marker operand as the source
address, the function block always uses the content of the
least significant byte for the initialization. If, for example, you
assign MD 6 to I1, the function block initializes with the content
of marker byte MB21.
Function block outputs
Description
Note
(Bit)
E1
Error output
1: if the number of elements exceeds the
source or destination range.
The range limits are checked irrespective
of the edge change on the Boolean T_
input. No data blocks are initialized or
copied if an error occurs.
E2
Error output
1: if the source and destination range overlap.
The range limits are checked irrespective
of the edge change on the Boolean _T
input. No data blocks are initialized or
copied if an error occurs.
E3
Error output
1: if the source or destination range are outside
of the available marker range (offset error, or
input NO is not configured i.e. has the value 0.
The range limits are checked irrespective
of the edge change on the Boolean T_
input. No data blocks are initialized or
copied if an error occurs.
Assigning operands
You can assign the following operands to the function block outputs that are numeric
outputs:
