System Overview 7
Chapter 2: System Overview
2.1 Architecture
A Max-ON RX3i Hot Standby Redundancy system consists of two PACSystems Max-ON RX3i
Controllers, at least one dedicated Ethernet Synchronization link, and an I/O system
comprised of at least one I/O LAN.
The Ethernet Synchronization link is used to exchange status and synchronization data
between the two Max-ON RX3i Controllers. For higher system availability, dual redundant
LANs may be employed.
The I/O LAN is used to communicate with the I/O devices that are attached to it. The I/O
system may be implemented using a combination of Ethernet drops (Series 90-30 ENIU or
PACSystems RX3i ENIU); or Genius drops (Genius I/O, Field Control I/O, VersaMax I/O, or
Remote I/O drops based upon Series 90-30 I/O). The example below shows the Max-ON RX3i
controllers connected to a single Ethernet I/O LAN.
Figure 9:
Max-ON RX3i has been designed to satisfy applications that have high performance
requirements. It has support for up to 8 simplex or 4 dual Genius I/O busses, and up to 3
Ethernet I/O busses.

2.2 Software Components
Max-ON RX3i software consists of several components, some of which execute in the Hot
Standby Controllers, and some of which execute in your programming workstation. A base
Logic Developer PLC Project provides the basic template for the Logic of the Redundant
System. This project is modified by the system designer to add the other necessary Logic to
perform the user application, and then the final application is stored in the Controllers using
PAC Logic Developer PLC.
You may think of the software provided in the Project template for the Controllers as
“drivers” that handle the complex tasks associated with Hot Standby redundancy. These
drivers allow the two Controllers to behave as a single Controller from the perspective of
your application.
The Max-ON RX3i Configuration Utility allows the system designer to customize the
parameters of the Max-ON RX3i drivers and to specify the hardware that is contained within
the system. The Max-ON Configuration Utility software operates in Windows XP
Professional, Windows NT4.0, and Windows 2000 Professional.
The Max-ON RX3i Configuration Utility software allows you to define the way your system is
constructed and how you want the system to operate. It provides additional information
that is not included in the Hardware Configuration files produced by Logic Developer PLC.
The Max-ON RX3i software includes a PAC View Diagnostic Project that allows you to
observe the way your system is operating and helps you to diagnose problems. This Project
displays the operational status of the redundant system in real time.
The Max-ON RX3i software also includes a set of projects to configure Series 90-30 Remote
Genius Drops.
The Max-ON RX3i software components are organized as follows:
Figure 11:
A Max-ON RX3i Quick Start Project is also included on the Max-ON RX3i Software CD. This
Quick Start Project also includes 3 RX3i ENIU targets.

System Overview 10
2.3 Hot Standby Redundancy Operation
During each controller scan, the Max-ON RX3i redundancy drivers are solved first, and then
your application logic is solved. The Max-ON RX3i redundancy drivers handle the following
functions:
•Determine Mastership –One CPU operates as the Master. The other operates as the
Backup. Output devices use the output states from the Master only. In a Max-ON
RX3i system, the user may specify either PLC to be the preferred Master. If no
preference is specified, then Mastership “floats” between the PLCs. The current
Master retains its status until it fails or until the user switches Mastership, at which
time the Master and Backup exchange their roles.
•Transfer Synchronization Data –If the Master fails, the Backup must be prepared to
control the process using the latest internal states from the ex-Master. These states
may represent such things as latched coils, timer/counter values, PID values, system
set points, and perhaps user-calculated values.
•Enforce an Orderly PLC Startup –When a failed PLC is returned to service, it must not
attempt to assume control of the system prior to being synchronized to the current
Master. If both PLCs startup simultaneously, then whichever one was the last valid
Master assumes the Mastership.
•Process Genius Dual Bus I/O Devices –When the system uses dual Genius I/O
busses, input devices are mapped automatically from the active I/O LAN into the
PLC’s input reference tables.
•Execute Diagnostic Tests –Automatically post time-stamped fault messages into
the Max-ON RX3i Alarm Table. Identify system problems such as bus faults, loss of
devices, change of Mastership, program restart, and power-up event.
2.4 Failover Time
The Mastership Time of the Max-ON RX3i system determines the Failover Time. The Failover
Time is the time required for control of the system to transfer from the Master Controller to
the Backup Controller.
Mastership Time: This is the time interval for the Backup Controller to recognize that the
Master Controller has failed. It takes one or two CPU scans plus one Synchronized Data
Transfer period to determine that the Master has failed. Then it takes an additional scan to
activate the output data stream in the Backup Controller.
For the Ethernet I/O LAN, the Remote Ethernet drop will start using the data from the
Backup Controller as soon as it detects that:
1. The Backup is now the Master
2. The Master is no longer sending data
For the Genius IO LAN, lacking output data from the current Master ’s GBC, each output
circuit on each device on the Genius I/O LANs will hold its last state for up to 2.5 seconds
before it assumes the Default State unless there is output data from the Backup GBC. (This

User Manual Chapter 2
GFK-2409B Oct 2019
System Overview 11
assumes that each device has been configured for either BSM present or for long timeout.)
Then the output device will begin using output data from the other GBC.
2.5 Synchronized Data Transfers
Data may be synchronized from the Master to the Backup on a continuous basis in order to
assure that the Backup controller’s data is always in sync with the Master’s. Max-ON
RX3isupports up to 6 groups of synchronization data for each data type listed below. The
groups do not have to be contiguous. Each group is specified by a starting reference address
and a length. For each data type, the lengths are added together, and the sum must not
exceed the value in the corresponding column below.

Discrete Outputs %Q
Internal Coils %M
Analog Outputs %AQ

2.6 I/O Bus Topologies
The Max-ON RX3i application supports the use of single (non-redundant) and/or dual
(redundant) busses interfacing to the I/O devices.
•A Max-ON RX3i controller supports up to four Ethernet LANs. At least one Ethernet
Interface must be dedicated to the Synchronization Link. This allows up to 3
additional Ethernet Interfaces that may be used as dedicated Ethernet I/O LANs.
Support is also available for a single duplex Ethernet I/O LAN.
Simplex Ethernet I/O Busses
Dual Ethernet I/O Busses
Up to 3
1
Note Redundant IP on the Primary and Secondary Synchronization LANs is not available
•Max-ON RX3i supports up to four redundant Genius LANs or up to eight non-
redundant Genius LANs, or a mixture of the two. However, the system may not have
more than eight Genius bus controllers in a Controller.
Simplex Genius I/O Busses
Dual Genius I/O Busses
Up to 8
Up to 4
Redundant busses are superior to non-redundant busses when there is a requirement to
protect against cable failures or Genius bus controller failures.
When the primary consideration is to protect against cable failures, then the system
designer should consider separating the cables so that a single mechanical failure does not
damage both cables.
2.7 Genius Dual Bus I/O Capacity
The maximum allowable I/O capacity for Max-ON RX3i redundant system that is configured
for Genius Dual busses is as follows:

2.8 Selecting the I/O
Max-ON RX3i systems may be implemented using any combination of the following I/O:
Ethernet NIUs
Ethernet NIUs are remote I/O drops that as based on standard 90-30 or
PACSystems RX3i hardware. These remote drops communicate to the
redundant controllers using Ethernet Global Data. These NIUs are configured
using Logic Developer PLC.
Genius Block
Genius blocks are intelligent, self-contained, configurable I/O modules. The
blocks are available as discrete, analog, and special purpose types, such as the
high- speed counter. Many of the blocks offer advanced diagnostic
capabilities such as open circuit, short circuit, and overload detection. Each
block is configured using a hand-held monitor.
Genius Field Control
Genius Field Control is a family of versatile, modular I/O devices. The I/O
modules are small and rugged and are available in both discrete and analog
versions.
I/O Terminal Blocks provide universal field wiring terminals for the I/O
modules, allowing I/O module types to be mixed on the same I/O Terminal
Block. The I/O Terminal block is mounted on a DIN rail.
As many as eight Field Control I/O modules (four I/O terminal blocks) can be
connected to one Bus Interface Unit. Together, they make up a Field Control
“station”. The bus interface unit provides either a single or a dual, redundant
LAN connection to the Hot Standby PLCs.
Each station is configured using a hand-held monitor.
Genius Remote 90-30
Drop
Genius Remote 90-30 drops consist of a Series 90-30 CPU, power supply, base
plate, and one Genius bus controller for a single LAN connection or two bus
controllers for a dual, redundant LAN connection. Normally, input and output
modules are installed in the base. A Scanner routine executes in the drop’s
CPU. This routine scans all input devices and transmits the input states to the
Hot Standby PLCs.
The routine also monitors outputs (%Q and %AQ) in the Synchronized Data
stream from the Hot Standby PLCs. Any output data that is configured to be
active in the remote drop is captured from the data stream and then is
mapped into the Drop’s output reference tables.
Configuration of the remote drop is accomplished using the Logic Developer
PLC software package. Also, a few rungs of ladder logic must be edited in
order to characterize the outputs in the drop.
Genius VersaMax
Genius VersaMax I/O products feature DIN-rail mounted modules with up to
eight I/O and option modules per “rack” and up to 8 racks per VersaMax I/O
Station system. Expansion racks can be located up to 750 meters from the
main VersaMax I/O Station rack. Expansion racks can include any VersaMax
I/O, option, or communications module.

User Manual Chapter 2
GFK-2409B Oct 2019
System Overview 13
Genius Third Party
In some cases, third party devices may be used on the LAN as well. These
devices must comply with the Genius I/O specification relating to Controller
Redundancy.
With a Max-ON RX3i system, you may select I/O devices based upon functionality, cost,
physical design, items carried in spare parts inventory, or personnel expertise.
2.9 Demo Mode Operation
A Max-ON RX3i application will operate in demo mode for 22 days on standard PACSystems
RX3i CPU hardware (IC695CPU310). In this mode, all the system’s capabilities are fully
operational. At the end of the demo period, PLC A will either stop immediately, if it is the
backup, or begin an orderly transfer of Mastership to PLC B. If the transfer is successful, then
PLC A will shut down automatically. At this point, the system will be operating in a
nonredundant manner.
A Max-ON RX3i system that is installed in a production environment MUST be running on a
Max-ON RX3i CPU (IC695CMU310) in order to allow PLC A to run indefinitely.
Running Max-ON RX3i on a standard RX3i CPU is helpful for short times in case of a hardware
failure or for non-production demonstration purposes.
