Bit Settings
Bits can be specified for input/output variables by any of the following methods.
1. Single bit
To specify only 1 of the bits, the target port number and bit number are specified in parentheses.
The port number may also be specified outside the parentheses.
Programming example: DOm(b)DOm(b)
Example: DO(25) Specifies bit 5 of port 2.
DO2(5)
2. Same-port multiple bits
To specify multiple bits at the same port, those bit numbers are specified in parentheses (separated
by commas) following the port number.
The port number may also be specified in parentheses.
Programming example: DOm(b,b,…,b) DO(mb,mb,…,mb)
Example: DO2(7,5,3) Specifies DO(27), DO(25), DO(23)
DO(27,25,23)
3. Different-port multiple bits
To specify multiple bits at different ports, 2-digit consisting of the port number and the bit number
must be specified in parentheses and must be separated by commas. Up to 8 bits can be written.
Programming example: DO(mb,mb,…,mb)
Example: DO(37,25,20) Specifies DO(37), DO(25), DO(20).
4. All bits of 1 port
To specify all bits of a single port, use parentheses after the port number. Methods 2 and 3 shown
above can also be used.
Programming example: DOm()
Example: DO2() Specifies all the DO(27) to DO(20) bits
→The same result can be obtained by the following:
DO(27,26,25,24,23,22,21,20)
or,
DO2(7,6,5,4,3,2,1,0)
