7.8. Data arrangement
The provision model of data is very similar to the one used in PROFIBUS DP, this will allow users of eNod4 Profibus an
easy recycling of their application.
7.8.1. Cyclic data (IO Data)
Cyclic exchanged data are either provided by the IO-Device and consumed by the IO-Controller or provided by the IOController and consumed by the IO-Device.
Data are contained in input or input/output modules (from the point of view of the IO-Controller). These modules are
defined in the GSDML file and are presented in a separate chapter.
The designer can select modules that he needs and place them in communication slots. Thus, the slots contain
modules. Slots are numbered. Slot 0 is not usable for data exchange, it contains DAP (Device Access Point)
informations which defines, among other, which data module can be contained in which slots.
7.8.2. Acyclic data (Records)
Acyclic data are available in read-only or read/write access. They are accessed by using a slot, a sub slot and an index.
eNod4 acyclic data are accessible with any slot and sub slot. Indexes for the eNod4 specific application data are
presented in appendix.
7.9. PROFINET IO exchange of cyclic data
Acyclic data modules are described in GSDML file. This file can be imported into the engineering tool used for
application design. Data modules can be freely plugged into any slot from 1 to 8. This will define the organization of
cyclic data in the AR (Application Relation). Unnecessary modules for the application may not be plugged. Inserting
data provided by eNod4 automatically implies the insertion of data consumed by eNod4 if the concerned module
contains consumed data.
