Assignment of inputs/ outputs to the process image
(Default Assignment / Assembly Object)
The IO Data Mapping describes the contents of the IO Data of the ILxxxxB520 in Receive and Transmit direction. The description is done by DeviceNet Assembly Objects. Each of the ILxxxx-B520 supports Assembly
Objects in each data direction. The input data/status or output data is mapped to a byte stream exchanged with the DeviceNet Master / Scanner by
IO-Data transfer.
The digital Signals are bit-oriented. This means that one bit in the process
image is assigned to each channel. The ILxxxx-B520 creates a memory
area containing the current input bits and ensures that the bits in a second
memory area dedicated to the output channels are written out immediately
The processing of analog signals is always byte-oriented. Analog input and
output values are represented in memory by two bytes each. Values are
represented in unsigned/signed integer or two’s complement format ( see
IExxxx manual). The number “0” stands for the input/output value “0 V”, “0
mA” or “4 mA”. Per default, Control and Status Bytes for each analog
channel are not mapped to the IO-data image. An analog channel is represented in the process image by two bytes
The ILxxxx-B520 supports extension boxes with other interfaces such as
RS232, RS485 incremental encoder, SSI Sensor interface. These signals
can considered similarly to the analog signals named above. For some
special signals the width of 16 Bit is not sufficient. The IL230x can Support
any byte width.
Once it has been switched on, the ILxxxx-B520 finds out how many Extension Boxes are connected and creates an assignment list. The analog and
digital channels, divided into inputs and outputs, are assembled into different parts of the list. The assignment starts on the first extension box next to
the ILxxxx-B520. The software in the ILxxxx-B520 collects the individual
entries for each of the channels in order to create the assignment list.

IO-Data which is transferred from the DeviceNet Master / Scanner to the
ILxxxx-B520 begins with byte-oriented values which is the data for the analog output and special signal extension boxes. The bit-oriented data for the
digital outputs of the ILxxxx-B520 and the digital output extension boxes is
transmitted after the byte-oriented data. If the total number of digital inputs
is not a multiple of 8, there will be a number of bits left over in the last data
byte. These will be discarded.

An extra status byte is transferred at the end of the Input Data and returns
the status of the ILxxxx-B520 with the following meaning:
Bit0: IL_Error : IO Error, internal Data exchange ILxxxx-B520 has failed
Bit1: IL-Cfg : ILxxxx-B520 Configuration Error
Bit2: reserved
Bit3: Diag : Diagnosis of analog Channel
Bit4: reserved
Bit5: reserved
Bit6: reserved
Bit7: FB_Error : Fieldbus Error / Idle Mode
The status byte corresponds to the Attribute “IL-Status” of the IL-Config
Object.
