2.1.2 Addressing rules
I/O counting method:
The address assignment of the inputs does not depend on
the address assignment of the outputs.
The counting method does not depend on the position of
the field bus node.
Counting is from left to right, depending on the module
type.
Modules of the same type are arranged linearly in the
address range, providing they are arranged one behind
the other.
I/Os of the same type each occupy their own station in
ascending order without gaps (digital I/Os, analogue
I/Os, I/Os of function modules).
The following I/Os are assigned separately:
Remote Ready (RR, CC Link−specific reserved, always
lies in the last reserved station)
Diagnostic I/Os (only if configured)
Digital I/Os
Analogue I/Os, I/Os of funcion modules
The following table applies for the sequence of address
assignment:
