Posted 4 April Hi, i'm doing a project that receive 3 values from MES: AutorizaçãoMES [DINT], OF_MES [DINT], and QtdExpectavel [UDINT]. I want a checksum calculation based in this 3 values. this is the code i made ToAryByte(In:=AutorizaçãoMES, Order:=_LOW_HIGH, aryout:= arrayChecksum[0]); ToAryByte(In:=OF_MES, Order:=_LOW_HIGH, AryOut:=arrayChecksum[4]); ToAryByte(In:=QtdExpectavel, Order:=_LOW_HIGH, AryOut:=arrayChecksum[8]); Checksum1 := arrayChecksum; Checksum_PLC_MES:=WORD_TO_UINT( AryCRC16(In:=arrayChecksum[0], Size:=uint#12, OutOrder := _HIGH_LOW)); in the attach i have the code simulation with values. The CRC16 result is not the expected, Can anyone help me with that? Thank you in advance Share this post Link to post Share on other sites
