Mitsubishi Electric MELSEC iQ-R Series - Reading the Specified Bit of the Word Label

1886
25 TYPE CONVERSION FUNCTIONS
25.66 Reading the Specified Bit of the Word Label
25.66 Reading the Specified Bit of the Word Label
GET_BIT_OF_INT(_E)
These functions read a value from the specified bit of a word label.
*1 FBD/LD is not supported. For FBD/LD, use the bit specification of labels.
Setting data
■Description, type, data type
Processing details
■Operation processing
• These functions output a value in the (n)th bit of (s).
■Operation result
1. Function without EN/ENO
The operation processing is performed. The operation result is output from (d).
2. Function with EN/ENO
The execution conditions and operation results will be as follows.
*1 If the value FALSE is output from ENO, the output data from (d) will be undefined. Create a program so that the undefined value will not
be used in operations.
Operation error
There is no operation error.
