Hi,

I have written an SCLmodule for use in PCS7which involves clearing/resetting values in a datablockto 0, the software looks a bit like this..

VAR_TEMP
pAny:ANY;
result:INT;
temp:BYTE;
END_VAR

VAR_INPUT
pC: BLOCK_DB;
pT : BLOCK_DB;
END_VAR

temp := 0;// constant of zero to write into destination data block
pAny:= pT;// pointer to the destination data block

result := FILL(BVAL := temp, BLK := pAny);


Can anyone tell me why this will not work? Also I find using PCS7 very frustratiing and slow, can anyone point me in the direction of some sample projects or SCL files?.

Thanks
