peration Error
In any of the following cases, an operation error occurs, the error flag (SM0) is turned ON, and
the corresponding error code is stored to SD0.
• There are characters within the data of
that are outside the range of 0 to 9.
(Error code: 4100)
• The device specified for
exceeds the corresponding device range. (For Universal
model QCPU only)
(Error code: 4101)
Program Example
(1) In the following program, the decimal ASCII data set in Var_D20 are converted to the 4-digit
BCD data, and the result is output to Y40 to Y4F.
[Structured ladder]
[ST]
DABCDP(SM400,Var_D20,K4Y40);
[Operation]
(2) In the following program, the hexadecimal ASCII data set in Var_D20 are converted to 8-digit
BCD data, and the result is stored to Var_D10, and also they are output to Y40 to Y5F.
[Structured ladder]
[ST]
IF SM400 THEN
DDABCDP(TRUE,Var_D20,Var_D10);
DMOV(TRUE,Var_D10,K8Y40);
END_IF;
