The input comparison instruction compares the data specified in S
double-precision floating point values (64-bit IEEE754 data) and creates an
ON execution condition when the comparison condition is true. When the data
is stored in words, S and S

bit data. The 64-bit floating-point data cannot be input as constants.
Inputting the Instructions
The input comparison instructions are treated just like the LD, AND, and OR
instructions to control the execution of subsequent instructions.
Input type
LD The instruction can be connected directly to the left bus bar.
AND The instruction cannot be connected directly to the left bus bar.
OR The instruction can be connected directly to the left bus bar.
