5.7.2.7 [427] Read long parameter 
  Type Function    Type Function 
I1 -  -  O1  % 
Long value 
Low word 
I2 -  -  O2  %  High word 
I3 b  Release read access  P1 i  Parameter number 
I4 -  -  P2 i  Data set (0 … 4)/index 
 
Description: 
The function reads the value of the parameter set up in P1 "Parameter number" and P2 "Data 
set/index". The value is converted to a long value. Via Input I3 read access is enabled. 
 
I3 = 0:  No read access. 
I3 = 1:  The parameter value is read. The instruction is executed until the value is read. 
5.7.2.8 [428] Read word parameter 
  Type Function    Type Function 
I1 -  -  O1  %  Parameter value [%] 
I2 -  -  O2  %  inverted output = -1 
I3 b  Release read access  P1 i  Parameter number 
I4 -  -  P2 i  Data set (0 … 4)/index 
 
Description: 
The function reads the value of the parameter set up in P1 "Parameter number" and P2 "Data 
set/index". The value is converted to a percent value. Via Input I3 read access is enabled. 
 
I3 = 0:  No read access. 
I3 = 1:  The parameter value is read. The instruction is executed until the value is read.

As long as status TRUE is present at I4 (Master Reset), the output value O1 is 0. 
 
Note: 
P2 can only be entered as a positive value.
