IC-Module for EtherNet/IP
52 / 137
Device Specific Objects
The following objects are specially for KUNBUS devices. These
objects allow you to access the input and output data with explicit
messages.
– Fieldbus Input Data, Class Code A0 hex
With this object you can read data sent from the KUNBUS-IC to the
EtherNet/IP master.
Application example: The data is copied from the SSC input area
(0x1001) via the data-broker to the fieldbus output area (0x2801).
You can read this data from class A0h, instance 1, attribute 1. This
attribute corresponds to the memory registers 0x2801 - 0x28f0.
– Fieldbus Output Data, Class Code A1 hex
With this object, data can be written, which is sent from the EtherNet/IP
master to the KUNBUS-IC.
Application example: The data is sent from the fieldbus input area
(register 0x1801) via the data-broker to SSC output area (0x2001).
This data can be written from the EtherNet/IP master via class A1h,
instance 1, attribute 1. This attribute corresponds to the memory
registers 0x1801 - 0x18f0.
– The variants with 2 ports can be used in a Device Level Ring (DLR).
Even though the module only supports the Announce based variant
from DLR, it can be used together with Beacon based modules in a ring.
6.3 Functions
The KUNBUS-IC supports the following functions.
– RPI
The smallest possible Requested Packet Interval (RPI) is 1 ms.
– ACD
The KUNBUS-IC supports Address Conflict Detection (ACD).
– DLR
The KUNBUS-IC can be used in a Device Level Ring (DLR).
