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

1890
25 TYPE CONVERSION FUNCTIONS
25.68 Copying the Specified Bit of the Word Label
25.68 Copying the Specified Bit of the Word Label
CPY_BIT_OF_INT(_E)
These functions copy the specified bit of the word label to the specified bit of another 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 copy the value in the (n1)th bit of the word specified by (s) to the (n2)th bit of (d).
■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.
