6. Function blocks
6.1 Manufacturer function blocks
Parameter error due to incorrect number or offset definition
Incorrect parameters are indicated whilst the program is running via the E1 - E3 error
outputs.
Parameter errors of this kind occur, for example, if the number of elements to be trans-
ferred exceeds the source or destination range, or when, due to an offset error, the
source and destination range are outside of the available marker range.
Transfer function blocks always copy or initialize marker
bytes, and never marker words or double words. This transfer
behavior does not depend on the values at I1 and I2 (source
address and destination address). You can copy a marker
double word, e.g., MD 12 to MD 96, by copying 4 marker bytes
with the function block.
