Refer to the function specifications table for each device in series
for the scope of device usage.
 S
1
: data source device 1. S
2
: data source device 2.
 This command compares the contents of S
1
and S
2
. Taking "FLD=" as an
example, if the result of comparison is “equal”, this command activates; but it
does not activate when the result is “unequal”.
 The FLD* command can directly input floating point numbers (for instance:
F1.2) to the S
1
, S
2
operands, or store floating point numbers in register D for
use in operations.
 You can use this command while directly to connect with the busbar
Api No.
