1 OVERVIEW
1.2 Data Specification Method
Bit data
Data size and data range
Bit data is handled in increments of bits such as contacts and coils.
Handling bit data with bit devices and labels
Bit data of one point per point can be handled.
Handling bit data with bit word devices
By specifying a bit number for a word device, bit data of the specified bit number can be handled.
A bit in a word device can be specified by "Word device number.Bit number".
A bit number can be specified in hexadecimal in the range from 0 to F.
For example, bit 5 (b5) of D0 is specified as D0.5, and bit 10 (b10) of D0 is specified as D0.A.
The following word devices support bit specification.
A bit number of a safety device used in safety programs executed by the Safety CPU can be specified in hexadecimal within
the range from 0 to F.
For example, bit 5 (b5) of SA\D0 is specified as SA\D0.5, and bit 10 (b10) of SA\D0 is specified as SA\D0.A.
The following word devices support bit specification.
