Quick Start
ControlNet PLC-5 Hot Backup System
(Including ControlNet PLC-5 Hot Backup Cartridge, Cat. No.
1785-CHBM)
The ControlNet PLC-5 backupsystem uses a pair of standard PLC-5/40 or
PLC-5/80 ControlNet processors, with I/O remotely connected to the
processors via ControlNet.
Note: For the ControlNet PLC-5 processors to operate in backup mode,
each processor must have the new ControlNet Backup Cartridge (Cat. No.
1785-CHBM) inserted into its EEPROM memory module slot.
UsingControlNet,thePLC-5processorscommunicatewitheachotherand
with ControlNet remote I/O to create a PLC-5 backup system that provides
high availability of control applications, where it is essential for continuity
in the process to be high.
This manual provides you with the information you need to get up and
running with your ControlNet PLC-5 backup system. For more detailed
information, refer to your ControlNet PLC-5 Hot Backup System User
Manual (publication 1785-6.5.24) and the ControlNet PLC-5
Programmable Controllers User Manual, phase 1.5 (publication
1785.6.5.22).

System Requirements
This section describes the components of the basic ControlNet PLC-5
backup system.

Installing The Hardware
Follow these steps to install the required hardware for your backup system.
1. Set the ControlNet node address numbers for each of the PLC-5
processors.
The addresses must be consecutive, with the lower number being odd.
For example, a valid node address pair is 1 and 2. You can set the
ControlNet node address via the rotary switches on the top of each
processor.
2. Insert the ControlNet backup cartridge into the EEPROM slot of each
PLC-5 processor.
Note: If the ControlNet backup cartridge is not inserted into the
PLC-5 processor, that processor will operate as a normal, standalone
processor, and will not exhibit any of the necessary backup functions.
3. Install each PLC-5 processor into a separate 1771 chassis.
4. Install a power supply for each chassis, and connect to ac power.
5. Wire the ControlNet network to the PLC-5 processors and to the I/O
adapters being used for the backup system.
The network cabling may consist of single or redundant channels.

Configuring Your Backup System
Before you begin, make sure that you have installed RSLinx, RSLogix5,
RSNetWorx, and the Hot Backup Configuration application software. For
assistance with installing any of these packages, refer to their respective
installation documentation.
You must complete the following steps to configure your backup system.
These steps assume that both processors are in the default memory state
(i.e., there is no program loaded).
1. Initialize the system.
2. Configure handshaking messages with RSNetWorx.
3. Configure I/O.
4. Create and configure the backup integer file.
5. Verify the backup system.
Initialize the System
To begin configuring your backup system, you must be sure that both
processors are in the initialized state. To do so:
1. Launch RSLogix 5.
2. Connect to the first processor.
3. Clear memory.
4. Assign a name to your project and save it.
5. Connect to the second processor, and repeat steps 3 and 4.

ControlNet PLC-5 Hot Backup System 5
Publication 1785-10.8 - October 1998
Configure Handshaking Messages With RSNetWorx
Within your backup system, you must use RSNetWorx to set up the send
and receive scheduled messages that allow handshaking to occur between
the two ControlNet PLC-5 processors that comprise your hot backup
system.
1. For each processor node of your backup system, you must create two
scheduled peer-to-peer messages; there must be one Send and one
Receive message for each. These messages must be exactly 5 words in
length.
2. Record the Send and Receive message numbers from the odd processor
node below:
Send message number: __________
Receive message number: __________
You will use these numbers later in the configuration process.
3. For the Requested Packet Interval (RPI), enter a value from 1 to 32,767.
This value must be no less than the NUT value, but no greater than 2
timestheNUT valueminus1. ThisvaluemustbethesameinbothPLC-
5 processors.
Configure I/O
Configure any adapters you have in your backup system by changing the
connection from the default setting of Exclusive Owner to a Redundant
connection.
Note: You must do this for BOTH processors.
Once you have changed the connection setting, you can save your
configuration. If the system is properly configured, the I/O LEDs on the
ControlNet PLC-5 processors will change from flashing red to solid green.

Create and Configure the ControlNet Backup Integer File
1. Launch RSLogix 5.
2. Create an integer file with a length of exactly 200 words. Do this on
both processors.
3. Launch the Hot Backup Configuration application software.
4. Enter the odd node address of the pair of modules in your system.
5. Select the RSLinx Driver you are using to attach to the PLC-5
processors.
6. Click on the processor you wish to configure, and set the following:
•Backup File - This is the 200-word integer data file number created
in RSLogix 5 (e.g. N20).
•Send Message - Enter the message number of the Send Scheduled
Message from the odd node address. (Refer to the number you
recorded earlier.)
•Receive Message - Enter the message number of the Receive
ScheduledMessagefromtheoddnodeaddress. (Refertothenumber
you recorded earlier.)
Refer to the ControlNet PLC-5 Hot Backup System User Manual
(publication1785-6.5.24)forotheroptionsonhowtoconfigureyour
backup system. (Other options include synchronous/asynchronous
modes, crossloading, and equivalence checking.)
If your system is properly configured, the QUAL LED on both backup
cartridges should be yellow. Your backup system is ready.

Verify the Backup System
To verify your system:
1. Place the odd node keyswitch in Run mode.
ThePrimaryLEDonthe1785-CHBMcartridgeshouldturnsolidgreen.
2. Place the even node keyswitch in Run mode.
The QUAL LED on both 1785-CHBM cartridges should turn solid
green. The Secondary LED on the even node should be solid yellow.
You now have a running ControlNet Hot Backup system.
