■Descriptions, types, and data types
Processing details
■Operation processing
• These functions convert the BOOL type data input to (s) to DWORD type data and output from (d).
• When the input value is "FALSE", these functions output 0H as the DWORD type data value.
• When the input value is "TRUE", these functions output 1H as the DWORD type data value.
• A value input to (s) is the BOOL type data value.
■Operation result
1. Function without EN/ENO
The operation processing is executed. The operation output value is output from (d).
2. Function with EN/ENO
The following table lists the execution conditions and operation results.
*1 When FALSE is output from ENO, data output from (d) is undefined. In that case, modify a program so that the data output from (d) is
not used.
Operation error
There is no operation error.
