Tell The Controller About The Device; Troubleshooting Tips; Using Electronic Data Sheet (Eds) Files - Balluff BNI004A Quick Start Manual

Tell the Controller About the Device

1. Every controller will need to know three things about the device being connected
2
over EtherNet/IP:
n The IP address of the block
n Where to look for the data (Instance ID) in the block
n
How much data is at the location (Data length)
2. Setup the block in the engineering software with the Instance ID and the Data
Length for the input data, the output data and the configuration data.
Instance ID: where the data is located in the device, sometimes called the
assembly instance number.
Data length: how much data to expect at this location, these are 8bit, 1byte
short integers. For controllers that read in 2byte words or in individual bit
counts, please see the Balluff website for the data assistance spreadsheet.
Input
Output
Configuration

Troubleshooting Tips:

n
For assistance with programming these values into a specific controller or
engineering software, please contact the controller manufacturer.
n Some controllers have a maximum data size below the 200 bytes required,
review the parameters of the controller before selecting.
n
Some controllers are using a third party device (such as an Anybus gateway)
to communicate over EtherNet/IP. These devices typically require additional
software to configure and establish communication properly.
Instance ID Data Length (Bytes)
100 200
101 134
102 98
