z The floating point value of S2 is subtracted from the floating point value of S1 and the result
stored in destination device D.
If a constant K or H used as source data, the value is converted to floating point before the
addition operation.

z The same device may be used as a source and as the destination. If this is the case then,
on continuous operation of the EADD instruction, the result of the previous operation
will be used as a new source value and a new result calculated. This will happen every
program scan unless the pulse modifier or an interlock program is used.
