Access via absolute addresses

You can also access the inputs and outputs of the system blocks via absolute addresses
according to standard IEC 61131−3:

For inputs:

For outputs:

%IXa.b.c

%QXa.b.c

a = node number
b = word address
c = bit address

In this Manual, the absolute addresses can be retrieved in the system variable table of the
corresponding system block.

Example: Table with the inputs of the SB Inputs_Digital of the ECSxA... axis module

Definition of the inputs/outputs

For connecting the application program with the hardware, system blocks are connected
with program organisation units (POU):
