control configuration.
• Open the DDS editors and <F2> to call up the input help which gives you a list of all available
system variables.
• This Manual lists the system variables in the corresponding system block table:
Variable name Data type Signal type Address DIS DIS format Note
DIGIN_bIn1_b %IX1.0.0 C0443/1
...
Bool binary
... ...
bin
DIGIN_bIn8_b
%IX1.0.7 C0443/8
Example: Table with SB DIGITAL_IO inputs of the Dive PLC
1.2.4 Access via absolute addresses
System block inputs and outputs can also be accessed via absolute addresses according to the IEC
1131-3 standard:
For inputs: For outputs:
%IXa.b.c %QXa.b.c
a = Module number
b = Word address
c = Bit address
• This Manual lists the addresses in the corresponding system block table:
Variable name Data type Signal type Address DIS DIS format Note
