QTS-CLX-APACS Module Overview

The QTS-CLX-APACS connects a ControlLogix controller to an APACS network.

Use the QTS-CLX-APACS to migrate APACS systems to ControlLogix controllers. You can retain the APACS I/O as the first step in the migration.

The module acts as either a monitor or as a master on the APACS IOBUS. You select the mode by downloading different firmware to the module, using the Windows configuration programs provided.

In monitor mode, the QTS-CLX-APACS sends APACS I/O input and output data to input data in the ControlLogix. It cannot transm it on the bus.

In master mode, the ControlLogix sends output data to the QTS-CLX-APACS, which then transmits it as output data on the APACS IOBUS. The QTS-CLX-APACS sends APACS input data to input data in the ControlLogix.

The QTS-CLX-APACS:

• supports IOBUS cable redundancy

• supports up to the maximum of 39 I/O cards allowed by the APACS IOBUS in a

maximum of 4 MODULRACS

IOBUS

The QTS-CLX-APACS communicates with the ControlLogix processor using scheduled connections. You configure the module in RSLogix 5000 (v19 or greater) with up to:

• 10 I/O connections, 9 for data and 1 for status

Page 2 QTS-CLX-APACS March 2015

Each I/O connection supports:

• scheduled input data, 496 SINTs or 124 REALs

• scheduled output data, 496 SINTs or 124 REALs

The Windows configuration programs supplied with the module map IOBUS data to the scheduled data. They also:

• upload and download configuration data

• map the IOBUS data to ControlLogix scheduled data

• save and open configuration files

• export aliases for use in your RSLogix 5000 application

• change the module mode, between monitor and master modes

Firmware Update

The module firmware can be updated using the Change Module Mode functions in the Windows utilities supplied (see page 44).

Part Number

The part number of the module is QTS-CLX-APACS.

Module Features

The following figure shows the features of the module.

The module has:

• A label that ident if ies th e m o du le, te x t 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 5-pin Phoenix connectors to connect to the IOBUS

A and IOBUS B bus cables

The module supports insertion and removal under power. 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 43) 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 43) with error code D0. In master mode, the module stops scanning and stops communicating with the ControlLogix.

Power Requirements

The QTS-CLX-APACS module requires 5 mA @ 24VDC and 475 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

You can install multiple QTS-CLX-APACS 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.

QTS-CLX-APACS Page 5

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.

Page 6 QTS-CLX-APACS March 2015

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 con figura tion to the

module.

• check that it has the correct master or monitor firmware and the correct version.

• ensure that the data has been synchronized

Figure 2 Inserting the Module

Cabling and Termination

QTS-CLX-APACS Page 7

WARNING!

Connect the QTS-CLX-APACS like any other IOBUS device. Refer to the following Siemens document for details on cabling:

Refer to section 2.10.2 of the manual shown above. Place the QTS-CLX-APA CS module at the beginning or end of the currently installed

MODULRAC racks:

Connecting the module disrupts bus traffic! Connect the module at a time when it is safe to do so.

• "APACS+ / QUADLOG MODULRAC and Local Termination Panel

Installation and Service Instructions", SD39MODULRAC-1

1. Purchase a Siemens cable that fits the end of the MODULRAC rack that will

be used (left side of first rack or right side of last rack).

2. Cut off the end of the cable that will connect to the QTS-CLX-APACS

module and strip the cabling.

3. Wire the Bus A signals IOBUS (+) to I/O A+, IOBUS (-) to I/O A-, MRET

to MRET and MEN to MEN on the top Phoenix connector.

4. Set the shunt plug on the MODULRAC from terminate to the I/O bus

continue position and place a 120 ohm resistor between I/O A+ and I/O Asignals on the top Phoenix connector.

Repeat steps 1 through 4 for IOBUS B cabling on the bottom Phoenix connector of the QTS-CLX-APACS module.

Terminate both ends of the IOBUS A and B using termination provided by the MODULRAC racks or a 120 ohm resistor attached to the physical ends of the bus, if the QTS-CLX-APACS module is placed at the beginning or end of the bus. There should be two and only two terminators on each bus.

The cabling is the same for monitor and master modes of the QTS-CLX-APACS.

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 QtsApacs_vx.x.exe on the CD to install the Windows software.

Page 8 QTS-CLX-APACS March 2015

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 monitor mode, the QTS-CLX-APACS sends APACS IOBUS input and output data to

input data in the ControlLogix. The QTS-CLX-APACS cannot transmit on the bus. In master mode, the ControlLogix sends output data to the QTS-CLX-APACS, which

then transmits it as output data on the APACS IOBUS. The QTS-CLX-APACS sends APACS input data to input data in the ControlLogix.

You should always access data using the aliases generated by the configuration programs.

Module Configuration

The ControlLogix configuration may be different for master and monitor modes of the QTS-CLX-APACS.

The Windows configuration tools show the required connections and minimum connection sizes.

The QTS-CLX-APACS module supports up to 10 scheduled connections. Connection 9 is reserved for diagnostics.

Discrete data is mapped from connection 0 upwards, analog data is mapped to connection 8 downwards.

Adding the Module

1. Place an ENBT in the I/O tree. Disable keying, set the Rack Connection to None, and set the slot to whatever slot the

QTS-CLX-APACS is in. The IP address doesn't matter, e.g., use Private Network 192.168.1.77 The Name doesn't matter, e.g., use ApacsEmuEnbt

QTS-CLX-APACS Page 9

2. Place another ENBT on the Ethernet under the first ENBT. Disable keying, set the Rack Connection to None, set the slot to 16. The IP Address doesn't matter, e.g., Private Network 192.168.1.78 Name this ENBT what you want the Controller Tag Name to be, e.g., APACS.

Make this name the same as the name you give the module in the configuration program (monitor or master).

This name will prefix all aliases.

TIP

This name will appear on the module’s 4-character scrolling display so you can easily identify it if you have more that one QTS-CLX- APACS module.

Page 10 QTS-CLX-APACS March 2015

3. Place generic 1756-MODULEs in slots 0 to 9, as required. The configuration programs assign IOBUS data to connections 0 to 8. Discrete inputs and

outputs and module status bytes are mapped to SINT data in connection 0 and up. That is, if connection 0 is full, the configuration programs start mapping data to connection 1, and so on.

Analog inputs and outputs are mapped to REAL data in connection 8 and down. That is, if connection 8 is full, the configuration programs start mapping data to connection 7, and so on

Diagnostic counters are mapped to INT data in connection 9. Right click on the backplane associated with the second ENBT and select New Module. Expand the Other tab, select a module of Type 1756-MODULE Generic 1756 Module

and click OK. RSLogix 5000 displays the New Module dialog box. Assign the module a Name and optionally a Description. Set the Slot to match the connection number

Connection for SINT data

Set the Comm Format to Data – SINT . Set the Connection Parameters as shown. The sizes sh own are the maxim um values.

QTS-CLX-APACS Page 11

Click OK

Connection for REAL data

Set the Comm Format to Data – REAL Set the Connection Parameters as shown. The sizes show n are the maxim um values.

Click OK.

Page 12 QTS-CLX-APACS March 2015

Connection for Diagnostic Data

Diagnostics are always mapped to connection 9. Connection 9 is not required but we strongly recommend that you create it.

Set the Comm Format to Data – INT Set the Connection Parameters as shown.

Do not reduce the connection size for connection 9 from the values shown. In addition to the diagnostic counters, other undocumented diagnostic information which may be useful for technical support is also mapped to connection 9.

The sizes of connections 0 to 8 (as needed) can be smaller than the maximum to reduce traffic in the ControlLogix backplane. Double click on the root of the network tree in the APACS configuration programs to determine the minimum connection sizes.

RPI

Next, set the RPI for the connection.

Selecting an RPI.

The module supports RPIs from 2.0 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. You can use different RPIs for each connection, depending on the requirements of your

application.

QTS-CLX-APACS Page 13

For example, you can use a longer RPI for the diagnostic data in connection 9, for example 500 milliseconds, since diagnostics do not need to be updated as frequently as I/O data.

Remote Connections

If you are using the QTS-CLX-APACS 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).

modules are all present and correct.

QTS-CLX-APACS Page 17

Double click on each module and confirm that the channel types for that module are all present and correct.

Assigning ControlLogix a ddresses

Select Tools/Auto-allocate CLX Addressing to map the APACS IOBUS data to ControlLogix addresses.

The module tree now shows the CLX addresses associated with each APACS module.

Page 18 QTS-CLX-APACS March 2015

What gets mapped

I/O Data

APACS IOBUS discrete inputs and outputs are mapped to the input data on ControlLogix connections from 0 upwards, as required. Discrete input and output data points consist of a byte of data and are mapped to SINT data in the ControlLogix. The low bit in each SINT corresponds to the value of the point (0 or 1, False or True).

APACS IOBUS analog inputs and outputs are mapped to the input data on ControlLogix connections from 8 downward, as required. Analog inputs and outputs are mapped to REAL data in the ControlLogix.

In addition, each discrete output, analog input and analog output has an associated status byte. These are also mapped to SINT input da ta in the ControlLogix, in connections 0 and up.

Diagnostic Counters

QTS-CLX-APACS diagnostic counters are integers are mapped to ControlLogix input data of type INT on connection 9.

Alias Name Offset Description StatRxGood 0 Good packets received from the network StatAbortErr 1 Bad packets, abort errors

QTS-CLX-APACS Page 19

Alias Name Offset Description StatBusANoiseErr 2 Bad packets, network noise StatFrameErr 3 Bad packets, framing errors StatCrcErr 4 Bad packets, CRC errors StatProtocolErr 5 Protocol errors StatRxTimeOut 6 Bad packets, timeout errors

Each alias name is prefixed by the module name and an underscore. In addition, bit 0 of the first word of output data on connection 9 is used for the command

to clear the diagnostic counters. The alias name is StatResetBit. The counters are cleared when this bit changes from 0 to 1.

Slot Status Bits

The QTS-CLX-APACS maintains an array of bits that indicate the status of the APACS modules.

In master mode, the bit is 0 if the module has good communication status and is 1 if the associated module is in error or is not responding.

Use the slot status bits to determine when you can access data from a module in master mode. Some APACS modules take several seconds to go online.

In monitor mode, the bits do not update and are always 0. Aliases to the bits are provided by the configuration tool for compatibility with master mode.

Aliases for these bits have names like

APACS_SlotStatus_R01S04

for the bit associated with the module in rack 1 slot 4. Use the aliases to access the status bits.

If the ControlLogix loses communication with the QTS-CLX-APACS, it sets the first four bytes of connection 0 to FF hexadecimal (11111111

TIP

binary). Monitor these four bytes to determine if there is a problem.

Setting the Module Name

To set the module name, right click on the QTS-CLX-APACS at the root of the tree and select Edit Module Properties.

Page 20 QTS-CLX-APACS March 2015

The QTS-CLX-APACS Module Properties dialog appears.

Enter the Module Name. It can be up to 15 characters long. It should follow the rules for naming ControlLogix aliases; it should contain only alphanumeric characters and the underscore. Click OK to accept the name.

The name is displayed on the 4-character disp lay and i s used by ClxApacsMonCfg to build aliases for ControlLogix data.

The default name assigned when you create a monitor configuration is MonImport. The name should be unique so that if you have more than one QTS-CLX-APACS

module, the aliases associated with each module are unique.

Use the same name that you assign the second ENBT module associated

TIP

with the QTS-CLX-APACS in RSLogix 5000 to make it easy to associate aliases with the module. See page 9.

Saving a Configuration Fil e

To save a configuration to disk, select File/Save or File/Save As.

Uploading and Downloading Conf igurations

To download a configuration to the QTS-CLX-APACS, select Tools/Download Configuration or use the Download Configuration to Module button on the toolbar.

To upload a configuration from the QTS-CLX-APACS, select Tools/Upload Configuration or use the Upload Configuration from Module bu tton on the toolbar. The

uploaded configuration will be given the default file name Untitled. If the RSLinx path to the module has not been set when you upload or download, an

RSLinx Path Selection window opens.

QTS-CLX-APACS Page 21

Page 22 QTS-CLX-APACS March 2015

Configuring the QTS-CLX-APACS Module in RSLogix 5000.

Follow the procedure on page 8 to configure the QTS-CLX-APACS in RSLogix 5000. To determine which connections you need to create, right click on the root of the tree and

select Edit Module Properties. The QTS-CLX-APACS Module Properties dialog box appears. It shows the required

connections and the minimum connection sizes.

Aliases

In the example shown, the required connections are:

• connection 0 with type SINT, minimum input size 70 and minimum output size 1

• connection 8 with type REAL, minimum input size 39 and minimum output size 1

In addition, connection 9 is always shown, although it is not required. Connection 9 is used for module diagnostics. It is recommended that you always create connection 9, with the sizes shown.

In monitor mode, the QTS-CLX-APACS does not wait for all connections to be open.

The configuration tool creates aliases for I/O data that can be exported and imported into RSLogix 5000.

Write programs using these aliases rather than using absolute addresses. If the mapping of the I/O data changes, simply reimport the new aliases and the program will point to the new data locations.

To export aliases, select Files/Export Alias File…

QTS-CLX-APACS Page 23

Enter the RSLinx Path Specifier to set the location of the module. This will be the name of the second ENBT module associated with the QTS-CLX-APACS modules (see page

8). In the example shown, the name is APACS. Type the FileName or use the Select File Name button to enter the file location where the

exported aliases will be saved. If you are using monitor mode to develop an application that will be used in master

mode, check the Create Temp Array Alias Tags checkbox. This creates aliases fo r the internal arrays you will need. Refer to page 25 for details.

Click OK to create the alias file.

WARNING!

Importing Aliases in RSLogix 5000

To import the alias file into RSLogix 5000, you must be offline. Select Tools/Import… and import the alia s file.

TIP

Alias Format

ClxApacsMonCfg builds each alias name from the Module Name and address information (Rack, Slot and Channel) supplied by the configuration program

The ControlLogix data address is built from the RSLinx Path Specifier you enter and the data mappings created by the configuration program.

If you change the I/O or ControlLogix configuration, re-import aliases so that the ControlLogix processor uses th e corre ct addr es ses and clear the ControlLogix output table so that values don’t get written to incorrect addresses.

If you have changed mode on the QTS-CLX-APACS, delete any aliases you previously imported into RSLogix 5000 before you import the new aliases.

Example:

ALIAS,"","APACS_AI_R01S06C02","APACS_AI_R01S06C02","","APACS:8:I.Data[1]"

Page 24 QTS-CLX-APACS March 2015

In this example, the module is in rack 1slot 6. The alias is for an analog input from channel 2 on the module, which is mapped to ControlLogix address input data at offset 1 of connection 8.

To build the alias name, ClxApacsMonCfg prefixes the name with the module name and an underscore. It prefixes the address with the RSLinx path specifier.

Opening a Configuration File

To open a configuration file, select File/Open.. This does not change the configuration in the module; the configuration in the module

changes only when you download.

Clearing the Configuration

To clear the configuration in the program, select File/New. This does not change the configuration in the module; the configuration in the module

changes only when you download.

Setting the RSLinx Path

Select Tools/Set RSLinx Path… to assign or change the current RSLinx path. This may be useful if, for example, you have more than one QTS-CLX- APACS module.

Changing the Module Mode

Select Tools/Change Module Mode… to switch a QTS-CLX-APACS module between monitor and master modes, or to update the module firmware (see page 44)

Select the firmware to download and click Apply. When the download is complete, ClxApacsMonCfg displays the version of the firmware downloaded.

QTS-CLX-APACS Page 25

Using Monitor Mode for Migration

You can use monitor mode on the QTS-CLX-APACS to migrate existing APACS applications to ControlLogix.

In monitor mode, the QTS-CLX-APAC S captures live inputs and outputs from the APACS IOBUS.

You first create two arrays in the ControlLogix:

• [Module name]_TempApacsSintOutputArray[8,500] of type SINT

• [Module name]_TempApacsRealOutputArray[8,125] of type REAL

The configuration program creates aliases for IOBUS inputs and outputs and for dummy outputs in the temporary arrays.

You import those aliases into RSLogix 5000, then create a new ControlLogix application that reads live inputs from the APACS IOBUS and writes outputs to the temporary arrays, always using the aliases from ClxApacsMonCfg.

You compare the outputs from the new ControlLogix application (in the temporary array) with the live outputs fro m IOBUS.

When you are satisfied that the new application duplicates the behaviour of the existing control application (state of outputs and timing), disconnect the APACS controller and switch the QTS-CLX-APACS module to master mode.

Export aliases from ClxApacsMasCfg in master mode and import them into RSLogix

5000. The names for the output aliases will be the same as those that previously pointed to the temporary array but now they will point to the corresponding IOBUS outputs. Your new ControlLogix application will write to the real outputs instead of the temporary array. Since you developed your application using these aliases, no further changes should be necessary.

You will start up with a ControlLogix application that has been tested and proven to duplicate the behaviour of the previous APACS control application.

Example: This is the alias ClxApacsMonCfg generated in monitor mode for a monitored discrete

output

ALIAS,"","APACS_DO_R01S04C01","APACS_DO_R01S04C01","","APACS_TempApacsSintOutp utArray[0,0]"

and this is the alias it generated for the same output in master mod e

ALIAS,"","APACS_DO_R01S04C01","APACS_DO_R01S04C01","","APACS:0:O.Data[0] "

The alias names are the same but in the first case the program wrote to the temporary SINT array; in the second it wrote to a ControlLogix output.

Similarly for analog outputs, this is the alias ClxApacsMonCfg generated in monitor mode for a monitored analog output

ALIAS,"","APACS_AO_R01S06C01","APACS_AO_R01S06C01","","APACS_TempApacsRealOutp utArray[0,0]"

and the corresponding alias in master mode

ALIAS,"","APACS_AO_R01S06C01","APACS_AO_R01S06C01","","APACS:8:O.Data[0] "

The alias names are the same but in the first case the program wrote to the temporary REAL array; in the second it wrote to a ControlLogix output.

Slot Status Bits

In monitor mode, the bits do not update and are always 0. Aliases to the bits are provided by the configuration tool for compatibility with master mode.

When you develop your control application using monitor mode, include logic that monitors the slot status bits to determine when you can access I/O data, so that the logic will be in place when you switch to master mode.

WARNING!

The following is a short summary of the steps typically followed. Refer to the appropriate manual section for details.

Master Mode Operation

Never connect the APACS in master mode to the network while the ACM is controlling I/O. It transmits even if there is no configuration and will disrupt communication.

Step Operation See page

1 Install the QTS-CLX-APACS module in the

ControlLogix chassis

2 Power down all APACS racks. 3 Connect the module to the APACS IOBUS 7 4 Run the QTS-CLX-MAS master configuration

program, ClxApacsMasCfg.exe

5 Temporarily load the monitor firmware on the

QTS-CLX-APACS

6 Clear the stored ACM configuration on the

QTS-CLX-APACS

7 Power up the APACS racks and wait for the OK

LEDs on all modules to be green

8 Read the captured configuration data that the ACM

sent to the modules

9 Check that all modules and channels are correct 28 10 Assign ControlLogix addresses to the IOBUS data 30 11 Set the module name 32

12 Save the configuration 33 13 Remove the ACM 14 Change the QTS-CLX-APACS to master mode 37

15 Download the configuration to the module 33 16 Configure the module in RSLogix 5000 8

17 Create aliases for RSLogix 5000 35 18 Import the aliases into RSLogix 5000 36 19 Use the aliases to access the data 38

ClxApacsMasCfg Software

The QTS-CLX-APACS module is supplied with a Windows configuration tool, ClxApacsMasCfg.exe for configuring the module as a master.

Use this configuration tool to:

• Switch between monitor and master mode

• Capture IOBUS configuration data from a running network

• Map I/O data to ControlLogix scheduled connections

• Save and load configuration files

• Set the RSLinx path to the QTS-CLX-APACS module

• Download and upload configurations

• Export aliases for I/O data for import into RSLogix 5000

• Update the module firmware

Configuring from an APACS IOBUS

The QTS-CLX-APACS master must be configured by capturing configuration information sent by an APACS ACM master to a running APACS IOBUS system at powerup. Power must be cycled to all APACS modules in all APACS racks in the system. All APACS modules must be present and configured. Check that the OK LEDs on all modules are green.

WARNING!

Wire the QTS-CLX-APACS as described on page 7. If you have been using monitor mode, the wiring does not need to be changed.

Power down all APACS racks. Run the master config tool, ClxApacs Ma sCfg .ex e. Select Tools/Change Module Mode to temporarily load the monitor firmware. Select Tools/Clear ACM Config to cl ear any previously stored configuration. Power up the rack and wait for the OK LEDs on all APACS modules to go green. Select Tools/ Read ACM Config to build the module tree from the configuration data the

QTS-CLX-APACS has captured..

Connecting the module to the IOBUS disrupts bus traffic! Connect the module only at a time when it is safe to do so.

Check the module tree and confirm that the APACS modules are all present and correct.

QTS-CLX-APACS Page 29

Double click on each module and confirm that the channel types for that module are all present and correct.
