Based on IEC 61131-3 programming, data processing occurs on site in the
controller. The process results can be output directly to the actuators, or
transmitted via the bus.
Process data is exchanged with PDOs and SDOs. The controller supports 512 TX
PDOs and 512 RX PDOs and SDOs to send process data via the CANopen
fieldbus.
In the local process image, a range of 4000 bytes serves as each input and output
range for data exchange via the CANopen interface. This range is situated
between the addresses 6000 to 9999. Direct access to the I/O modules via the
fieldbus is not provided.
All entries of the object directory can be mapped as required to the RX PDOs and
TX PDOs. The complete input and output process image can be transmitted via
SDOs.
10.1 Object Directory
All communication objects and all user objects are compiled in the object
directory. The figure below provides a rough overview of this:
Table 207: Overview of Addresses in the Object Directory
Reserved (addresses used for other services)
Up to eight standardized device profiles
Process images from IEC 61131 devices
Process images from CANopen gateways acc. CiA 302-7
The objects, which are made available by the controller, are described below.
