(1) In any of the following cases, an operation error occurs, the error flag (SM0) turns ON, and
an error code is stored into SD0.
• The format designated by was neither 0 nor 1. (Error code: 4100)
• A value other than 0 to 9 exists in the each digit of + 1 and + 2. (Error code: 4100)
• The format designation made by + 3 is something other than 0 or 1.
(Error code: 4100)
• The exponent data designated by +4 is outside the range of from 0 to 38.
(Error code: 4100)
• The decimal fraction digit designated by is outside the range of from 0 to 7.
(Error code: 4100)
• The device specified by exceeds the range of the corresponding device.
(For the Universal model QCPU, LCPU.) (Error code: 4101)
Program Example
(1) The following program converts the BCD type floating decimal point format data being
stored in devices starting from D0 to 32-bit floating decimal point type real number data
based on the decimal fraction digit being stored at D10, and stores the result at D100 and
D101 when X0 goes ON.
