List of error codes
Error code Description
103H A value out of the range is set in i_uDataType (data type selection).
Set a value of 0 to 2 in i_uDataType (data type selection).
105H A value out of the range is set in i_udSize (number of data points).
Set a value of 1 to 1000000 in i_udSize (number of data points).
200H Although the value set in i_uDataType (data type selection) is
Single-precision real number, the stored input array data is not a
single-precision real number. Store the data as a single-precision
real number in the file register (ZR).
205H i_bEN (execution command) has been turned off during the
processing.
209H Some areas of input array data and output array data are
overlapped. Review the following settings so that the input array
data areas and the output array data areas are not overlapped.
• i_udInAryAddr (input array data start address)
• i_udOutAryAddr (output array data start address)
• i_udSize (number of data points)
Description
(1) This FB does not include the error recovery processing. Prepare the error recovery processing separately to suit the
user's system and the expected operation.
(2) This FB uses the long index register LZ0. When using an interrupt program, do not use the corresponding index
register.
(3) The FB cannot be used in an interrupt program.
(4) Using the FB in a program that is to be executed only once, such as a subroutine program or a FOR-NEXT loop, has a
problem that i_bEN (execution command) can no longer be turned off and normal operation is not possible; Always use
the FB in a program that is capable of turning off the execution command.
(5) The FB requires the configuration of the ladder for every input label.
