16.4 Inspection Execution and Result Output Procedures
Notes
To output judgment results, set Environment − Parallel Output
− Judgment to “Out” (even with this setting, zeros are output
once).
When outputting numerical calculation results, set
Environment − Parallel Output − Numerical Calc. to “Out”
(even with this setting, if there are no numerical calculations
set, the data will be output once as zeros, regardless of the
data width).
For judgment output, handshaking is performed until the data
has been output from the last specified external output
register (JD).
For numerical calculations, CA registers that have not been
set, and CA registers that perform output control are skipped
(not output).
The output data length for numerical calculation results can
be set separately for each of 8 groups, CA01 to CA04, CA05 to
CA08, CA09 to CA12, CA13 to CA16, CA17 to CA20, CA21 to
CA24, CA25 to CA28, and CA29 to CA32.
The numerical range that can be handled by each of these
data lengths is as follows (if a number outside of the range is
output, the overflow flag goes on).
8 bits: 0 to 255
16 bits: 0 to 65535
32 bits: − 2147483648 to 2147483647
