9.1 Inputs, Outputs and Marker Flags

I Input
I1 Input, Connector X3
I1.00 Input, Connector X3, Group 0 (Byte)
I1.00.6 Input, Connector X3, Group 0, Bit 6
Inputs
The inputs are designated with ’I.’ They can be programmed and
processed in the parameters, commands, and in the Logic Task. They
are read at the beginning of each cycle or at the start of the Logic Task.
Outputs
The outputs are designated with ’Q.’ They can be programmed and
processed in the parameters, commands, and in the Logic Task. They
are processed at the beginning of each cycle or at the start of the Logic
Task. If an output is designated in the Logic Task, this output can no
longer be processed in one of the NC Tasks or via the functions activated
in the parameters.
Flags
The marker flags are designated with ’M.’ They can be programmed and
processed in the parameters, commands, and in the Logic Task. They
are processed at the beginning of each cycle or at the start of the Logic
Task. To avoid confusion, the NC Task and the Logic Task have different
marker flags. Transfer flags handle the exchange of information between
the NC Task and the Logic Task.

Origin or category
Byte
8 inputs, outputs or marker flags are grouped together (to form bytes).
BIT
The bit designates an input, output or marker flag. Numbering is from 0 to 7.
