Safety Precautions
Please read the following safety precautions carefully.
Terms and Abbreviations
For a complete listing of Allen-Bradley terminology, refer to the
Allen-Bradley
Industrial Automation Glossary , Publication AG-7.1.
!
ATTENTION: Only personnel familiar with
DeviceNet products and associated machinery should
plan or implement the installation, start-up,
configuration, and subsequent maintenance of the
DeviceNet absolute encoder. Failure to comply may
result in personal injury and/or equipment damage.
!
ATTENTION: Remove all power before installing the
DeviceNet absolute encoder. Failure to disconnect
power may result in death or serious injury. Verify all
power is removed before installing the DeviceNet
absolute encoder.
!
ATTENTION: Hazard of equipment damage exists. If
explicit messages are programmed to frequently write
parameter data to the 842D EEPROM, the EEPROM can
exceed its life cycle and cause the product to
malfunction. Do not create a program that frequently
uses explicit messages to write parameter data to a
product. (See EEPROM Life specification on page A-1.)
Terms Definition
DeviceNet An open network that provides probabilistic I/O control
through a managed bit-wise non-destructive multiplexing
scheme.
842D
DeviceNet
Encoder An Allen-Bradley encoder that communicates directly with the
DeviceNet network without requiring additional adapters. In
this manual, the terms “encoder” and “842D” are also used
when referring to the 842D DeviceNet Encoder.
RSNetWorx
for
DeviceNet A Rockwell Software application that can be used to set up
DeviceNet networks and configure connected devices.
RSNetWorx for DeviceNet (version 3.00.00) and RSLinx
(version 2.20.02) were used for examples in the manual.
Different versions may differ in appearance and procedures.
