Chapter 3 Install the Enhanced Redundancy System
Add the EDS Files
Some modules have the EDS files already installed. However, if needed, obtain
EDS files for modules in your system from the Rockwell Automation Support
website at: http://www.rockwellautomation.com/resources/eds/ .
Once you have downloaded the required EDS file, launch the EDS Hardware
Configuration Tool by choosing Start > Programs > Rockwell Software® >
RSLinx Tools > EDS Hardware Installation Tool.
The tool then prompts you to Add or Remove EDS files.
Step 2: Install the Hardware Follow these steps to set up and install your system’s hardware components.
Install the First Chassis and its Components
When you install an enhanced redundancy system, install one chassis, and its
necessary components, at a time.
Module Placement and Partnering
Each pair of controllers and communication modules must be comprised of
compatible partner modules. Two modules in the same slot are considered as
compatible partners only if they contain compatible hardware and firmware and
other rules that can be enforced by the module itself. The compatibility status
(Compatible or Incompatible) is determined by either the module in the primary
chassis or its partner in the secondary chassis.
The redundancy module pair must occupy the same slots in their respective
chassis. The redundancy module pair does not consider the chassis pair to be
partnered if the redundancy modules are placed in different slots, even if the
partners of other modules are present in the same slot.
IMPORTANT When using the 1756-RM2/A or 1756-RM2XT module, you must use version
8.01.05 or later of the RMCT.
TIP When the redundancy module firmware is upgraded, the RMCT is updated.
The RMCT automatically uses the version that is compatible with the
redundancy module firmware revision installed.
