Dear all,

I have written a SCL function, with two outputs defined as Byte Array[1..999] & Word Array[1.999] respectively. After I compiled the SCL file, and inserted the generated FC into the program, I got a problem to assign the parameter for these two outputs.

I have already pre-defined two arrays in a DB, as shown in the attached picture, Error_Data_Type as Byte Array[1..999] and Error_Code as Word Array[1..999]. But when I tried to assign these two arrays to the outputs 'Q_ERROR_DATA_TYPES' & 'Q_ERROR_CODES' of FC212 on the right, I got an error, and the information was 'Declaration range of the actual side does not fit the formal declaration range VAR_OUTPUT of the formal parameter Q_ERROR_DATA_TYPE.'

In my SCL function, I declared the arrays as below:     

Does anyone have any idea why there was such error?

Thanks.

Hi kevinlin_5,

I got the same result, but tried the symbol instead.

Try: "Diagnos_MBTCP_DG03".Error_Data_Type

Also get into the habit of using Array index starting from 0, because the SCADA will start at 0.

ARRAY[0..999] instead of ARRAY[1..999].

Good luck!
