4.14 Process Data Configuration
• Fixed I/O data transferred
DeviceNet handles I/O data transparent as a byte string without defining any data type in the
transferred data. To be operative it defines only the number of bytes in consumed and produced
direction that shall be transferred across a connection, nothing else. But HSyCon and the firmware
now allows to assign modular each byte or a bunch of bytes of the transparent string to different data
types. A list of the supported data types of the connection can be found in the middle table of the
window called
Available Predefined Connection Data Types .
The following data types are supported:
• Bit, Byte, Word, Dword, Byte Array
If the data type Byte Array is chosen the number of bytes that shall be reserved for this data type can
be entered in the Data Count column in the lower table. Any other data type has its fixed length that
can not be changed. The data types are distinguished in process output and process input data in the
view of the Master device.
A double-click on a predefined data type or a click in the Add to configured I/O data button will
insert the chosen data type in the lower table called Configured I/O connection data. This table
contains all data that shall be really transferred across the connection. HSyCon will add separately
the number of used bytes of each configured I/O data and forms the values Consumed and
Produced Connection Size automatically. Both values indicates the sum of bytes which shall be
sent by the Master as outputs (Consumed by the device) and received by the Master as inputs
(Produced by the device).
• Assigning the process data offset addresses
The I/O offset addresses of each placed data type in the connection data table can be freely
configured in a range of 0 to 3583 or they are set automatically by HSyCon. To enable or disable free
configuration use the flag Auto Addressing in the menu Settings - Auto Addressing. If enabled
HSyCon will place all configured I/O data, without spaces in physical order one after another based
on the rising MAC-ID order. This is done during the download procedure. The assigned addresses
can be checked then in the overview Address Table of the menu View. If the addresses are entered
manually the default address 0 in the input address respectively the output address must be
overwritten. Depending on the Addressing mode in the DNM Master Settings the addresses are
byte addresses or word addresses. This is described in the chapter Addressing mode.
