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.
The notation for bit number specification is as follows.
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.
Handling bit data with word type labels
By specifying a bit number for a word [unsigned]/bit string [16 bits] type label or word [signed] type label, bit data of the
specified bit number can be handled.
The notation for bit number specification is as follows.
Data name Data size Value range
Bit data 1 bit 0, 1
