Rockwell Automation 1756-HYD02 ControlLogix Hydraulic Servo Module - Manual (Page 46)

46 Publication 1756-UM525A-EN-P - June 2003
Chapter 4 Using the 1756-HYD02 Module Features
Automatic Firmware Update for the module via the Firmware Supervisor
feature from a Logix5000 controller.
EXAMPLE
In the following scenario, Exact Match keying prevents I/O
communication:
• The module configuration is for a 1756-IB16D module with module
revision 3.1. The physical module is a 1756-IB16D module with
module revision 3.2. In this case, communication is prevented
because the Minor Revision of the module does not match
precisely.
IMPORTANT
Changing electronic keying selections online may cause the I/O
Communication connection to the module to be disrupted and may
result in a loss of data.
