QTS-CLX-PVX Module Overview
The QTS-CLX-PVX connects a ControlLogix controller to a PROVOX®Control I/O
bus.
The QTS-CLX-PVX is intended to be used to migrate PROVOX systems to
ControlLogix controllers. You can retain the PROVOX I/O as the first step in the
migration.
The module can act as a monitor or as a master on the Control I/O bus. You select the
mode by downloading different firmware to the module.
In monitor mode, the QTS-CLX-PVX sends PROVOX I/O input and output data to input
and status input data in the ControlLogix. It cannot transmit on the bus.
In master mode, the ControlLogix sends output data to the QTS-CLX-PVX, which then
transmits it as output data on the PROVOX Control I/O bus. The QTS-CLX-PVX sends
PROVOX input data to input data in the ControlLogix.
The QTS-CLX-PVX:
supports I/O bus redundancy
supports 20-series Control I/O files 1-16
supports up to 64 I/O cards. For larger systems, split the bus and use two
QTS-CLX-PVX modules.
supports 10 series I/O with serial buffer card
does not support EIC or IDI

Page 2 QTS-CLX-PVX September 2009
does not support Control I/O card redundancy
The QTS-CLX-PVX communicates with the ControlLogix processor using scheduled
connections. You configure the module as a Generic Module in RSLogix 5000 with:
250 16-bit words of scheduled input data
248 16-bit words of scheduled output data
250 16-bit words of status input data
The Windows configuration program supplied with the module maps Control I/O bus
data to the scheduled data. It also:
uploads and downloads configuration data
downloads firmware to the module
saves and opens configuration files
exports aliases for use in your RSLogix 5000 application
Firmware Update
The module firmware can be updated using the Windows utility supplied (see page 32).
Part Number
The part number of the module is QTS-CLX-PVX
Module Features
The following figure shows the features of the module.
The module has:
A label that identifies the module, text QTS
Universal Comm
A 4-character scrolling display
3 LEDs, labelled NET, CLX, and OK, to indicate
the status of the I/O bus, the state of the connection
to the ControlLogix processor, and the internal state
of the module
2 BNC connectors to connect to the primary and
secondary I/O bus cables
The module supports insertion and removal under power.

QTS-CLX-PVX Page 3
The module is shipped in monitor mode, with a blank configuration.
Watchdog and Jabber Inhibit
A watchdog timer is implemented in the module’s hardware. If the firmware does not
kick the watchdog within the timeout period the watchdog times out and generates a fatal
error (see page 31) with error code D1. In master mode, the module stops scanning and
stops communicating with the ControlLogix.
A jabber inhibit timer is implemented in the module’s hardware. If the bus transmitter is
on longer than 150% of the longest frame time, the jabber inhibit forces the transmitter
off and generates a fatal error (see page 31) with error code D0. In master mode, the
module stops scanning and stops communicating with the ControlLogix.
Power Requirements
The QTS-CLX-PVX module requires 675 mA @ 24VDC and 5 mA @ 5.1VDC from I/O
chassis backplane.
Other Requirements
To use the Windows utility programs, you must have RSLinx software, version 2.54 or
later, with an activation. Use RSLinx Gateway or RSLinx Professional software. Do not
use RSLinx Lite.

Installation
Prevent Electrostatic Discharge
The module is sensitive to electrostatic discharge.
WARNING!
ATTENTION: Electrostatic discharge can damage integrated circuits
or semiconductors if you touch backplane connector pins. Follow these
guidelines when you handle the module:
Touch a grounded object to discharge static potential
Wear an approved wrist-strap grounding device
Do not touch the backplane connector or connector pins
Do not touch circuit components inside the module
If available, use a static-safe work station
When the module is not in use, keep it in its static-shield packaging
Prepare the Chassis for Module Installation
Before you install the ControlLogix module, you must install and connect a ControlLogix
chassis and power supply. To install these products, refer to the installation instructions
you received with them.
Determine Module Slot Location
This example shows chassis slot numbering in a 4-slot chassis. Slot 0 is the first slot and
is always located to the right of the power supply. You can use any size ControlLogix
chassis and install the module in any slot.
Figure 1 Chassis Slots

QTS-CLX-PVX Page 5
You can use multiple modules in the same chassis.
Insert the Module in the Chassis
The ControlLogix module is designed to be installed or removed while chassis power is
applied.
WARNING!
ATTENTION: When you insert or remove the module while
backplane power is on, an electrical arc can occur. This could cause an
explosion in hazardous location installations. Be sure that power is
removed or the area is nonhazardous before proceeding.
Repeated electrical arcing causes excessive wear to contacts on both the
module and its mating connector. Worn contacts may create electrical
resistance that can affect module operation.

Replacing a Module
If you are replacing an existing module with an identical one, and you want to resume
identical system operation, you must:
install the new module in the same slot.
run the configuration program and download the appropriate configuration to the
module.
check that it has the correct firmware, scanner or monitor version.
ensure that the data has been synchronized

Cabling and Termination
WARNING!
Connecting the module disrupts bus traffic!
Connect the module at a time when it is safe to do so.
Connect the QTS-CLX-PVX like any other device on the Control I/O bus.
The bus cable is 75-ohm RG-6, for example Belden 9290
Terminate both ends of the primary and secondary I/O bus using 75 ohm resistors
attached to the physical ends of the bus. There should be two and only two terminators on
each bus.
Refer to the following Emerson documents for details on cabling:
section 3.8 of "Installing and Maintaining the SRx Controller Family",
PN8.0:CL6640
Installing Control I/O Subsystem (PN2.1:CP6701)
Signal Wiring and Highway System Guidelines PN1:004
Software Installation
You must uninstall any previous version of the software before you can install a new
version. Use the Windows Control Panel Add and Remove Programs to remove the old
version.
Insert the CD supplied and run the program QtsPvx.msi on the CD to install the Windows
software.

Important Considerations
The operation of the QTS-CLX-PVX is different in several important ways from that of a
standard ControlLogix module and in some ways from a PROVOX controller.
It is essential that you be aware of the following:
the QTS-CLX-PVX in master mode write changes in the ControlLogix output data
table to PROVOX outputs even in program mode. If you make a change in the output
table, it will appear on the bus
in master mode, if the I/O configuration in the QTS-CLX-PVX changes, it is
essential that you clear the ControlLogix output table for the module before you
connect it to the Control I/O bus
the QTS-CLX-PVX continues to scan the Control I/O bus even if the the connection
to the ControlLogix processor is lost. This is so that I/O on the bus does not time out.
on the Control I/O bus, data is passed only when it changes. In monitor mode, the
QTS-CLX-PVX sees only data that changes while it is connected to the bus. In
master mode, the QTS-CLX-PVX writes outputs only when they change and receives
inputs only when they change.
configuring the QTS-CLX-PVX module requires that you reset the PROVOX
controller. This can cause major disruptions to the running system. Reset the
controller only when you know it is safe to do so. A reset can last up to 3 minutes.
if you switch from a real PROVOX scanner to a QTS-CLX-PVX scanner, you
should download the configuration to the QTS-CLX-PVX. This forces a reset on the
Control I/O bus. A reset is necessary because the two scanners implement the bus
token passing slightly differently. A reset ensures that all files and cards update.

Page 10 QTS-CLX-PVX September 2009
Configuring the Module in RSLogix 5000
You configure the module in RSLogix 5000 to set how much scheduled data to transfer
and how often to transfer it.
The terms input and output are relative to the ControlLogix.
In master mode, the ControlLogix sends output data to the QTS-CLX-PVX, which then
transmits it as output data on the PROVOX Control I/O bus. The QTS-CLX-PVX sends
PROVOX input data to input data in the ControlLogix.
In monitor mode, the QTS-CLX-PVX sends PROVOX I/O input and output data to input
and status input data in the ControlLogix. It cannot transmit on the bus.
You should always access data using the aliases generated by the configuration program.
Module Configuration
Configure the module as a Generic module in RSLogix 5000.
The same ControlLogix configuration is used for master and monitor modes of the QTS-
CLX-PVX.
Adding the Module
To add the module to the I/O configuration in RSLogix 5000, you must be offline.
1. If you are creating a new project, select File/New to create a new project,
give the processor a name, and enter the slot it occupies in the ControlLogix
rack.
2. Right click on the I/O configuration Folder, or on the bridge module in
the desired remote chassis in the I/O Configuration Folder, and select
New Module…
3. Expand the Other tab, select a module of Type 1756-MODULE Generic
1756 Module and click OK.

QTS-CLX-PVX Page 11
4. RSLogix 5000 displays the New Module dialog box.
5. Assign the module a Name and optionally a Description.
6. Set the Comm Format to Data –INT –With Status.
7. Set the Slot to match the slot number of the QTS-CLX-PVX module in the
chassis.

Page 12 QTS-CLX-PVX September 2009
8. Set the Connection Parameters as shown above. Click OK.
9. Next set the RPI.
10. Click OK to accept the module
Selecting an RPI.
The module supports RPIs from 0.2 to 750.0 ms. The default RPI is 5 ms.
Select an RPI appropriate to the I/O bus scan time and to your process. It makes no sense
to use an RPI that is much faster than the bus or process update time. Typical RPIs are
from 100 to 150 ms.
Remote Connections
If you are using the QTS-CLX-PVX in a remote chassis, for example a chassis connected
to the controlling ControlLogix processor over Ethernet or ControlNet, it may be
necessary to increase the RPI, as the intermediate network may not have sufficient
bandwidth to support faster updates (small RPIs).
I/O Data Mapping
The configuration program (see page 14) maps the I/O data to ControlLogix tags.
The configuration program creates aliases to I/O data that you can import into RSLogix
5000 to access I/O data. The alias names address data by file, card and channel.
Use these aliases to access data in any applications you develop. If the mapping changes,
you simply re-import aliases and the application accesses the correct I/O location. The
configuration program also creates aliases to diagnostic data which is not easily
accessible other than by using the aliases.
