Processing details
■Operation processing
• BOOL_TO_INT, BOOL_TO_INT_E
Converts bit type data input to (s) into word (signed) type data, and outputs the operation result from (d).
When the input value is FALSE, 0 is output in word (signed) type data.
When the input value is TRUE, 1 is output in word (signed) type data.
s
FALSE
TRUE
Bit type
• BOOL_TO_DINT, BOOL_TO_DINT_E
Converts bit type data input to (s) into double word (signed) type data, and outputs the operation result from (d).
When the input value is FALSE, 0 is output in double word (signed) type data.
When the input value is TRUE, 1 is output in double word (signed) type data.
