Name  Function 
Data 
type 
a transition in an 
output pin’s signal 
from low to high 
Time when there is a 
transition in an output pin’s 
signal from high to low 
Error 
An error 
occurs in the 
function 
block. 
BOOL 
  An error occurs 
when the function 
block is executed. 
  There is transition in the 
Error output pin’s signal 
from high to low when 
there is a transition in the 
Execute input pin’s signal 
from high to low. 
  If the Execute input pin is 
set to False when an error 
occurs, the Aborted output 
pin will be set to False in 
the next cycle. 
 
ErrorID  Error code  WORD 
  Please see the status 
code table below. 
  0B: A parameter is 
incorrect. 
0C: The module does 
not support the 
function.

Data which 
is read 
DWORD[2]   
When there is a 
transition in the 
Done output pin’s 
signal from low to 
high, the value of 
the DataRead 
output pin is 
updated.
