Table 208: Indexing Of "Iec 61131-3" Variable Data In The Object Directory - WAGO I/O SYSTEM 750 Manual

WAGO-I/O-SYSTEM 750
750-8208 PFC200 CS 2ETH RS CAN DPM
As CANopen does not transfer data by bits, the variable data is combined from a
Boolean data type to bytes and assigned to the corresponding index; Boolean
input variable data is assigned to index 0xA080, Boolean output variable data to
index 0xA500.
Variable data that has a data width of 1 byte or more is assigned to the
corresponding indices in a similar manner.
Observe the direction of data flow!
The IEC 61131-3 input variables are defined from the perspective of the CAN
bus. These are output variables from the perspective of the PFC. Accordingly, the
IEC 61131-3 output variables are input variables for the PFC.
This table provides an overview of the indices of "IEC 61131-3" variables.

Using the associated indices for data types with a data width of 1 byte (Integer8,
Unsigned8 and Boolean), read-only byte-by-byte access is possible from the
fieldbus to data in the controller memory.
The sub-index is utilized to select a specific byte.
