Remarks
- In FBD
"Function block diagram"
A function block diagram describes a function between input variables and output variables. A function is described as a set of elementary blocks and FFLD language, the block NEG can be used.
FBD Language
FFLD Language
- In the FFLD language, the conversion is executed only if the input rung (EN) is TRUE.
- The output rung (ENO) keeps the same value as the input rung.
- The negation is executed only if EN is TRUE.
- ENO keeps the same value as EN.
IL Language
Not available.
ST Language
- In the ST "Structured text"
A high-level language that is block structured and syntactically resembles Pascal language, "-" can
be followed by a complex Boolean expression between parentheses.
- The output data type must be the same as the input data type.
Q := -IN;
Q := - (IN1 + IN2);
