Operands:

: Source device 1 S

: Source device 2

Explanations:

1. This instruction compares the content in S

and S

. Take “FLD=” for example, if the result is “=”,

the continuity of the instruction is enabled. If the result is “≠”, the continuity of the instruction is

disabled.

2. The user can specify the floating point value directly into operands S

and S

(e.g. F1.2) or

store the floating point value in D registers for further operation.

3. FLD※ instruction is used for direct connection with left hand bus bar.
