Battery Life Advisory

The MVI46, MVI56, MVI69, and MVI71 modules use a rechargeable Lithium Vanadium Pentoxide battery to backup the real-time clock and CMOS. The battery should last for the life of the module. The module must be powered for approximately twenty hours before the battery becomes fully charged. After it is fully charged, the battery provides backup power for the CMOS setup and the real-time clock for approximately 21 days. When the battery is fully discharged, the module will revert to the default BIOS and clock settings.

Note: The battery is not user replaceable.

1.3 Setting Jumpers

If you use an interface other than RS-232 (default), you must change the jumper configurati on to match the interface. There are three jumpers located at the bottom of the module.

The following illustration shows the MVI56-LTQ jumper configuration:

1 Set the PRT 2 (for application port 1) and PRT 3 (for application port 2)

jumpers for RS232, RS422, or RS485 to match the wiring needed for your application. The default jumper setting for both application ports is RS-232.

2 The Setup Jumper acts as "write protection" for the module’s flash memory.

In "write protected" mode, the Setup pins are not connected, and the module’s firmware cannot be overwritten. Do not jumper the Setup pins together unless you are directed to do so by ProSoft Technical Support.

1.4 Installing the Module in the Rack

If you have not already installed and configured your ControlLogix processor and power supply, please do so before installing the MVI56-LTQ module. Refer to your Rockwell Automation product documentation for installation instructions.

Warning: You must follow all safety instructions when installing this or any other electronic devices. Failure to follow safety procedures could result in damage to hardware or data, or even serious injury or death to personnel. Refer to the documentation for each device you plan to connect to verify that suitable safety procedures are in place before installing or servicing the device.

After you have checked the placement of the jumpers, insert MVI56-LTQ into the ControlLogix chassis. Use the same technique recommended by Rockwell Automation to remove and install ControlLogix modules.

Warning: 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. Verify that power is removed or the area is non-hazardous 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.

1 Turn power OFF. 2 Align the module with the top and bottom guides, and slide it into the rack

until the module is firmly against the backplane connector.

3 With a firm but steady push, snap the module into place. 4 Check that the holding clips on the top and bottom of the module are securely

in the locking holes of the rack.

5 Make a note of the slot location. You must identify the slot in which the

module is installed in order for the sample program to work correctly. Slot numbers are identified on the green circuit board (backplane) of the ControlLogix rack.

6 Turn power ON.

Note: If you insert the module improperly, the system may stop working, or may behave unpredictably.

2.3.5 BlkDelay

This is an empirical value used by the module to balance the amount of time the module spends block transferring and the amount spent handling port communications. The value entered is used as a loop counter in the module, where each time through the loop the count is incremented. When the count equals the Block Transfer Delay Counter a Block Transfer sequence is initiated.

Example: In Master Mode applications with the module in a remote rack, the frequency of command execution can be improved by entering a value of 75 to

150. The value must be determined empirically.

2.3.6 LastState

This value determines the state of the Limitorque read register values that are returned to the PLC upon the detection of a communication failure state (that is, comm has failed on both Port A and B).

Clear last data values (default)

2.3.7 NetPoll

Loop Mode (Port 1 and 2 alternating)

The Network Loop Mode emulates Limitorque’s polling scheme that takes advantage of the actuator ability to repeat data transmissions and to operate in a looped mode. In this mode, the module will alternate communications between Port 1 and 2. Command failures on one port will be retried on the other port.

Ladder logic is required for application of the MVI56-LTQ module. Tasks that must be handled by the ladder logic are module data transfer, special block handling, and status data receipt. Additionally, a power-up handler may be needed to handle the initialization of the module’s data and to clear any processor fault conditions.

The sample ladder logic, on the ProSoft Solutions CD-ROM, is extensively commented, to provide information on the purpose and function of each rung. For most applications, the sample ladder will work without modification.

3.1.2 User Data Objects

These objects hold data to be transferred between the processor and the MVI56LTQ module. The first user data object is the LTQBackplane object that contains the variables required by the ladder logic program for data transfer between the module and the processor. The following table describes the structure of this object.

Values in this structure are used by the ladder logic and initialized by the powerup function. The values in this block should change very rapidly as the transfer process is very fast.

Information in this structure contains the status and monitor information for each valve in the system. This information should be considered by the user control logic to determine the status and control required for each valve to be utilized in a system. It is important to note that slave 1 has an array index of 0. This offset applies to all valves (slave 150 has an index of 149).

The next data set received from the module is the DoneBits array. Each slave in the system is associated with a bit in the array. Each element contains the done bit status for 16 slave units ([0]=slaves 1 to 16, [1]=slaves 17 to 32, and so on). It is important to use these bits to clear the commands issued using the next data sets. Commands issued to the module to generate messages on the Limitorque Valve Network are issued in a one-shot operation. After an event command is issued to the slave, the done bit for the slave is set. This bit is held high for one scan of the module and then is reset in the data transfer block. Ladder logic should clear the commands for each slave using the status of the done bit.

The last set of data in the module object contains the control information for the valves. This data is to be controlled by the ladder logic. An array is defined for each of the command instructions available through the module. Each bit in the array is associated with a slave. Bit 0 in word 0 corresponds to slave 1, and Bit 0 in word 1 corresponds to slave 17. An array of LTQCont objects is defined for the contactor engage/disengage commands. The following table describes the structure of this object.

In order to execute one of the commands, set the bit for the selected slave in the array. For example, to open slave-3 valve, set bit 2 in word 0 of the Open array. For the analog control commands, set the value for the analog first (AnalogPos[ ]), then set the analog control array bit (AnalogCmd[ ]). The analog position requires two commands. The first command issued by the module sets the position in the valve. The second command instructs the valve to seek the new position.

4.1.1 Clearing a Fault Condition

Typically, if the OK LED on the front of the module turns RED for more than ten seconds, a hardware problem has been detected in the module or the program has exited.

To clear the condition, follow these steps:

1 Turn off power to the rack. 2 Remove the card from the rack. 3 Verify that all jumpers are set correctly. 4 If the module requires a Compact Flash card, verify that the card is installed

correctly.

5 Re-insert the card in the rack and turn the power back on. 6 Verify correct configuration data is being transferred to the module from the

ControlLogix controller.

If the module's OK LED does not turn GREEN, verify that the module is inserted completely into the rack. If this does not cure the problem, contact ProSoft Technology Technical Support.

4.3 Reading Status Data from the Module

The MVI56-LTQ module returns a 22-word Status Data Block that can be used to determine the module’s operating status. This data is transferred to the ControlLogix processor continuously with each read block.

The Configuration/Debug port provides the following functionality:

 Full view of the module’s configuration data  View of the module’s status data  Complete display of the module’s internal database (registers 0 to 3999)  Version Information  Control over the module (warm boot, cold boot, transfer configuration)  Facility to upload and download the module’s configuration file

4.3.1 Required Software

In order to send and receive data over the serial port (COM port) on your computer to the module, you must use a communication program (terminal emulator).

A simple communication program called HyperTerminal is pre-installed with recent versions of Microsoft Windows operating systems. If you are connecting from a machine running DOS, you must obtain and install a compatible communication program. The following table lists communication programs that have been tested by ProSoft Technology.

4.3.2 The Configuration/Debug Menu

The Configuration and Debug menu for this module is arranged as a tree structure, with the Main Menu at the top of the tree, and one or more sub-menus for each menu command. The first menu you see when you connect to the module is the Main menu.

Because this is a text-based menu system, you enter commands by typing the command letter from your computer keyboard in the terminal application (for example, HyperTerminal). The module does not respond to mouse movements or clicks. The command executes as soon as you press the command letter — you do not need to press [Enter]. When you type a command letter, a new screen will be displayed in your terminal application.

Navigation

All of the submenus for this module contain commands to redisplay the menu or return to the previous menu. You can always return from a submenu to the next higher menu by pressing [M]

The organization of the menu structure is represented in simplified form in the following illustra tion:

on your keyboard.

The remainder of this section shows the menus available for this module, and briefly discusses the commands available to you.

Keystrokes

The keyboard commands on these menus are usually not case sensitive. You can enter most commands in lowercase or uppercase letters.

The menus use a few special characters (?, as shown. Some of these characters will require you to use the SHIFT,

ALT

keys to enter them correctly. For example, on US English keyboards, enter

the ?

command as SHIFT and /.

Also, take care to distinguish the different uses for uppercase letter "eye" (I),

-, +, @) that must be entered exactly CTRL, or

lowercase letter "el" (L), and the number one (1). Likewise, uppercase letter "oh" (O)

and the number zero (0) are not interchangeable. Although these characters

Diagnostics and Troubleshooting MVI56-LTQ ♦ ControlLogix Platform User Manual Limitorque Valve Actuator Master Communication Module

From this menu, you can select the "Port", the "format", and the "ticks" that you can display the data in.

For most applications, HEX is the best format to view the data, and this does include ASCII based messages (because some characters will not display on HyperTerminal and by capturing the data in HEX, we can figure out what the corresponding ASCII characters are supposed to be).

The Tick value is a timing mark. The module will print a _TT for every xx milliseconds of no data on the line. Usually 10milliseconds is the best value to start with.

After you have selected the Port, Format, and Tick, we are now ready to start a capture of this data. The easiest way to do so is to go up to the top of you HyperTerminal window, and do a T

RANSFER / CAPTURE TEXT as shown below:

After selecting the above option, the following window will appear:

Next name the file, and select a directory to store the file in. In this example, we are creating a file ProSoft.txt and storing this file on our root C: drive. After you have done this, press the button.

Now you have everything that shows up on the HyperTerminal screen being logged to a file called ProSoft.txt. This is the file that you will then be able to email to ProSoft Technical Support to assist with issues on the communications network.

5.1 Product Specifications

The MVI56 Limitorque Valve Actuator Master Communication Module allows ControlLogix compatible processors to interface easily with Limitorque Valve Actuators and other Limitorque protocol compatible devices.

The MVI56-LTQ module acts as an input/output module between the Limitorque valve network and the ControlLogix processor. The data transfer from the ControlLogix processor is asynchronous from the actions on the network. The 1500-word register space in the module transfers the valve information from the module to the processor. Ladder logic is responsible for control of the valves. Data transferred from the processor to the module instructs the module to execute commands to valves on the Limitorque network.

5.1.1 General Specifications

 Single Slot - 1756 backplane compatible  Local or remote rack  The module is recognized as an Input/Output module and has access to

processor memory for data transfer between processor and module

5.2 Functional Overview

5.2.1 General Concepts

The following discussion explains several concepts that are important for understanding module operation.

ControlLogix Processor Not in Run

Whenever the module detects that the processor has gone out of the Run mode (that is, Fault or PGM), the ports can be shut down as prescribed in the user configuration. When the processor is returned to a running state, the module will resume communications on the network.

Backplane Data Transfer

The MVI56-LTQ module communicates directly over the ControlLogix backplane. Data is paged between the module and the ControlLogix processor across the backplane using the module's input and output images. The update frequency of the images is determined by the scheduled scan rate defined by the user for the module and the communication load on the module. Typical updates are in the range of 1 to 10 milliseconds.

This bi-directional transference of data is accomplished by the module filling in data in the module's input image to send to the processor. Data in the input image is placed in the Controller Tags in the processor by the ladder logic. The input image for the module is set to 250 words. This large data area permits fast throughput of data between the module and the processor.

The processor inserts data to the module's output image to transfer to the module. The module's program extracts the data and places it in the module's internal database. The output image for the module is set to 248 words. This large data area permits fast throughput of data from the processor to the module.

MVI56-LTQ ♦ ControlLogix Platform Reference Limitorque Valve Actuator Master Communication Module User Manual

The following illustration shows the data transfer method used to move data between the ControlLogix processor, the MVI56-LTQ module and the Limitorque valve network.

All data transferred between the module and the processor over the backplane is through the input and output images. Ladder logic must be written in the ControlLogix processor to interface the input and output image data with data defined in the Controller Tags. All data used by the module is stored in its internal database. The following illustration shows the layout of the database:

Normal Data Transfer

Normal data transfer includes the paging of the valve data found in the module’s internal database in registers 0 to 1499, the status data and the done bit data from the module to the processor. These data are transferred through read (input image) blocks 0 to 7. Data transferred from the processor to the module is through blocks 0 and 1. The structure and function of each block is discussed in the following topics.

The Read Block ID is an index value used to determine the location of where the data will be placed in the ControlLogix processor controller tag array of module read data. Each transfer can move up to 200 words (block offsets 2 to 201) of data representing the data for up to 20 valves. In addition to moving valve data, the block also contains status data for the module. This last set of data is transferred with each new block of data and is used for high-speed data movement.

User Manual Limitorque Valve Actuator Master Communication Module

The LTQ Module returns Done Bit Data to the ladder logic. A single bit is returned per slave address, allowing ladder logic to be used to clear the Command Enable bits. The following important points should be noted about the Command Done bits:

1 There is only one bit returned per slave address, not one bit per command

per slave. The implication of this is that one Done Bit must be used to clear all possible Enable bits for one slave address.

2 The Done Bit is a positive indication that the module executed the command.

It is NOT an indication of the command’s success. A Done Bit is returned to the ladder logic whenever the command was completed without error or not. This allows all commands to be unlatched. To determine if there is a communication problem with a slave, verify the Channel A/B communication status bits in the valve data Status field.

3 The Done Bit data registers in the module are cleared and then updated prior

to each backplane transfer sequence. This is done to ensure that the ladder logic receives the quickest possible acknowledgment of a command’s execution.

The structure of the Done Bit Data in the input image from the module is as follows:

Cmd Done - Slaves 17 to 32

Cmd Done - Slaves 113 to 128 Cmd Done - Slaves 129 to 144

The following tables can be used to determine the slave associated with each bit in the array. These tables can also be used with the digital control words discussed in the following section. The following table lists the relationship between the word/bit combination and the slave address on the Limitorque valve network:

Page 62 of 98 ProSoft Technology, Inc. August 30, 2010

MVI56-LTQ ♦ ControlLogix Platform Reference Limitorque Valve Actuator Master Communication Module User Manual

The following table lists the relationship between the word/bit combination and the slave index in the module:

The module status data starts at word 212 in the read block. This information can be used to determine the "health" of the module and should be moved to the status object in the processor logic.

The Write Block ID associated with the block requests data from the ControlLogix processor. Under normal program operation, the module sequentially sends read blocks and requests write blocks. For example, if eight read and two write blocks are used with the application, the sequence will be as follows:

R0W0R1W1R2W0R3W1R4W0R5W1R6W0R7W1R0W0

This sequence will continue until interrupted by other write block numbers sent by the controller or by operator control through the module’s Configuration/Debug port.

Configuration Data Transfer

When the module performs a restart operation, it requests configuration information from the ControlLogix processor. This data is transferred to the module in specially formatted write block (output image). The module will poll for the block by setting the required write block number in a read block (input image). Refer to Module Configuration for a description of the data objects used with the blocks and the ladder logic required. The following topics show the format of the blocks for configuration.

Module Configuration Data

This block sends general configuration information from the processor to the module. The data is transferred in a block with an identification code of 9000. The following table shows the structure of this block.

Command Control Blocks

Command control blocks are special blocks used to control the module or request special data from the module. The current version of the software supports two command control blocks; warm boot and cold boot.

Warm Boot

This block is sent from the ControlLogix processor to the module (output image) when the module is required to perform a warm-boot (software reset) operation. The block is commonly sent to the module any time configuration modifications are made in the controller tags data area. This causes the module to read the new configuration and restart. The following table shows this structure:

Cold Boot

This block is sent from the ControlLogix processor to the module (output image) when the module is required to perform the cold boot (hardware reset) operation. This block is sent to the module when a hardware problem is detected by the ladder logic that requires a hardware reset. The following table describes the format of the control block.

5.2.2 Data Flow Between MVI56-LTQ Module and ControlLogix Processor

The following topics describe the flow of data between the two pieces of hardware (ControlLinx processor and the MVI56-LTQ module) and nodes on the Limitorque valve network. In the Master mode, the MVI56-LTQ module is responsible for issuing read or write commands to slave devices on the Limitorque valve network. These commands are generated from a fixed set of commands contained in the module. The module issues the read commands continuously. Write commands are issued under ladder logic control. The following flow chart and associated table describe the flow of data into and out of the module.

1 The module obtains configuration data from the ControlLogix processor. This

configuration completely defines the operation parameters for the module.

2 After configuration, the module begins transmitting read commands to the

valves on the network. If an event command (a bit in one of the digital control word arrays is set) is recognized by the module, it will issue the associated write command to the valve. The done bit for the event will be set in the DoneBit array.

3 Presuming successful processing by the node specified in the command, a

response message is received into the driver for processing.

4 Data received from the node on the network is passed into the module’s

internal database (only for read function messages).

5 Status and done bit array data is returned to the ControlLogix processor. Refer to Module Configuration (page 21) for a complete description of the

parameters required for configuration of the module.

5.3 Cable Connections

The application ports on the MVI56-LTQ module support RS-232, RS-422, and RS-485 interfaces. Please inspect the module to ensure that the jumpers are set correctly to correspond with the type of interface you are using.

Note: When using RS-232 with radio modem applications, some radios or modems require hardware handshaking (control and monitoring of modem signal lines). Enable this in the configuration of the module by setting the UseCTS parameter to 1.

5.3.1 RS-232 Configuration/Debug Port

This port is physically an RJ45 connection. An RJ45 to DB-9 adapter cable is included with the module. This port permits a PC based terminal emulation program to view configuration and status data in the module and to control the module. The cable for communications on this port is shown in the following diagram:

5.3.2 RS-232 Application Port(s)

When the RS-232 interface is selected, the use of hardware handshaking (control and monitoring of modem signal lines) is user definable. If no hardware handshaking will be used, here are the cable pinouts to connect to the port.

MVI56-LTQ ♦ ControlLogix Platform Reference Limitorque Valve Actuator Master Communication Module User Manual

RS-232: Modem Connection (Hardware Handshaking Required)

This type of connection is required between the module and a modem or other communication device.

The "Use CTS Line" parameter for the port configuration should be set to 'Y' for most modem applications.

RS-232: Null Modem Connection (Hardware Handshaking)

This type of connection is used when the device connected to the module requires hardware handshaking (control and monitoring of modem signal lines).

ProSoft Technology, Inc. Page 69 of 98 August 30, 2010

Reference MVI56-LTQ ♦ ControlLogix Platform User Manual Limitorque Valve Actuator Master Communication Module

RS-232: Null Modem Connection (No Hardware Handshaking)

This type of connection can be used to connect the module to a computer or field device communication port.

Note: For most null modem connections where hardware handshaking is not required, the Use CTS Line parameter should be set to N and no jumper will be required between Pins 7 (RTS) and 8

(CTS) on the connector. If the port is configured with the Use CTS Line set to Y, then a jumper is required between the RTS and the CTS lines on the port connection.

Reference MVI56-LTQ ♦ ControlLogix Platform User Manual Limitorque Valve Actuator Master Communication Module

5.3.5 RS-485 Application Port(s)

The RS-485 interface requires a single two or three wire cable. The Common connection is optional, depending on the RS-485 network devices used. The cable required for this interface is shown below:

Note: Terminating resistors are generally not required on the RS-485 network, unless you are experiencing communication problems that can be attributed to signal echoes or reflections. In these cases, installing a 120-ohm terminating resistor between pins 1 and 8 on the module connector end of the RS-485 line may improve communication quality.

RS-485 and RS-422 Tip

If communication in the RS-422 or RS-485 mode does not work at first, despite all attempts, try switching termination polarities. Some manufacturers interpret + and -, or A and B, polarities differently.

5.8 Polling Schemes

In Looped Mode, the LTQ provides communication redundancy to each configured slave on the network. The LTQ monitors the health of each communication path between port 1 and each configured slave and between port 2 and each configured slave. LTQ port 1 communication status between port 1 and the addressed slave is recorded in the slave Channel A status bit. LTQ port 2 communication status between port 2 and the addressed slave is recorded in the slave Channel B status bit. Both Channel A and Channel B status bits are located in the slave Status register, bits 10 and 11(Word 1, bits 10 and 11).

On a healthy network where all configured slaves are communicating; the LTQ will first poll all slaves via port 1, then poll all slaves via port 2, back to port 1, and so on. As each slave is successfully polled, the respective Channel bit is set to 0 in the slave Status register. Remember the LTQ port 1 equals Channel A and the LTQ port 2 equals Channel B.

Should a slave not be reached on a poll, the LTQ will set the corresponding Channel Fail bit to 1, switch to the other port and attempt to communicate with the same slave. Should the slave not communicate from the second port, the corresponding Channel Fail bit will be set to 1, and the LTQ will resume polling on the original port. After the LTQ has completed polling all configured slaves on the first port, the polling routine will switch to the other port and repeat the above process.

Example:

There are 5 slaves on the network and slave number 3 has been turned off. The LTQ is currently polling the slaves through the LTQ port 1 (Channel A). Slave number 1 and 2 respond to the LTQ port 1 poll. Slave number 3 does not respond to the port 1 poll causing the LTQ to set slave 3 Channel A bit to 1. The LTQ now changes to port 2 (Channel B) and polls slave number 3. Slave number 3 does not respond to the port 2 poll causing the LTQ to set the slave 3 Channel B bit to 1. Next the LTQ changes back to port 1 and attempts to poll slave number 4. This communication attempt is successful and the LTQ now polls slave number 5 through the LTQ port 1. Slave number 5 responds completing the port 1 poll.

Next the LTQ repeats the process through port 2 (Channel B). Slave 1 and 2 respond, slave 3 does not respond and the LTQ sets the slave 3 Channel B bit to

1. The LTQ changes to port 1 (Channel A) and attempts to communicate with slave 3. Slave 3 does not respond, the LTQ sets the slave 3 Channel A bit to 1, switches back to port 2 and resumes polling the remainder of the configured slaves. Once slaves 4 and 5 have been successfully polled via port 2, the LTQ then switches to port 1 and repeats the polling process. The port alternation process described above continues until slave 3 is powered on and the communication fault clears.

Commands for slave control interrupt the polling process and are issued through the current poll port. After the slave has acknowledged the command, the LTQ resumes the polling process. In the event of a communication fault between the current poll port and a commanded slave, the LTQ will issue the command through the other communication port.

Example 1:

The LTQ is successfully communicating to each slave and sets the bits equating to Channel A and B to 0. A value of 0 in the Channel A and B status indicate successful communication.

Example 2:

The LTQ is successfully communicating to slaves 1, 2, 4, and 5 via both ports. Slave number 3 is without power causing the slave 3 network board bypass relays to de-energize. This de-energizing of the bypass relays shorts the signal through the network board and isolates the slave from the DDC-100 network.

Example 3:

The LTQ is successfully communicating to slaves 1, 2, 3 via port 1 and 4, 5 via port 2. When a slave does not communicate within a predetermined time-out period the LTQ sets the corresponding Channel bit to a value of 1. This example indicates a wiring problem between slave 3 & 4. This problem is typically a cable breakage, short, or improperly terminated wire.

Example 4:

The LTQ is attempting to communicate to the slaves via both ports but is unable to reach any slaves via port 2. This typically indicates a broken cable connection at port 2 or at the first slave from port 2, broken or shorted cable between the LTQ and the first slave from port 2, improperly terminated wires, or loss of power to the RS-232/485 converter if attached to the LTQ port 2.

Example 5:

The LTQ is successfully communicating to each slave and sets the bits equating to Channel A to 0. A value of 0 in the Channel A status indicates successful communication.

Example 6:

The LTQ is successfully communicating to slave 1, 3, 4, and 5. Slave 2 does not respond causing the LTQ to set slave 2 Status register bit 10 to 1. In this example, slave 2 is without power causing the slave 2 network board bypass relays to de-energize. This de-energizing of the bypass relays shorts the signal through the network board and isolates the slave from the DDC-100 network.

Example 7:

The LTQ is successfully communicating to slaves 1 and 2 but is not able to communicate to slaves 3, 4, and 5 causing the LTQ to set slave 3, 4, 5 Status register bit 10 to 1. This typically indicates a broken or shorted cable between slave 2 and 3, a broken cable connection at slave 2 or 3, improperly terminated wires at slave 2 or 3, or loss of power to slaves 3, 4, and 5.
