Battery Life Advisory

All modules in the MVI series use a rechargeable Lithium Vanadium Pentoxide battery to backup the 51 2K SRAM memory, 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 it becomes fully charged. After it is fully charged, the battery provides backup power for the CMOS setup and configuration data, the real-time clock, and the 512K SRAM memory for approximately 21 days. Before you remove a module from its power source, ensure that the battery within the module is fully charged. A fully charged battery will hold the BIOS settings (after being removed from its power source) for a limited number of days. When the battery is fully discharged, the module will revert to the default BIOS settings.

Note: The battery is not user replaceable.

2.3.29 Counter with Flag

Yes or No This parameter determines which variation will be returned for object 20 when

the master requests variation 0. If the parameter is set to N, variation 5 will be returned. If the parameter is set to Y, variation 1 will be returned.

Note: Flag will always be set for Online and cannot be changed through by the PLC or user

program. Only the default variation returned by the module will be affected by changing this parameter.

2.3.30 Frozen Counter with Flag

Yes or No This parameter determines which variation will be returned for object 21 when

the master requests variation 0. If the parameter is set to N, variation 9 will be returned. If the parameter is set to Y, variation 1 will be returned.

Note: Flag will always be set for Online and cannot be changed through by the PLC or user

program. Only the default variation returned by the module will be affected by changing this parameter.

2.3.31 Time Sync Before Events

Yes or No This parameter determines if events are to be generated by the module before

the time synchronization from the master unit. If the parameter is set to N, events will be generated irrespective of the module's time sync status. If the parameter is set to Y, events will be generated only if the module's time is synchronized.

2.3.32 Use Trip/Close Single Point

Yes or No If you set this parameter to Yes, Trip/Close events will function like Pulse On

operations. Only one bit will be reserved in the DNP BO database. If you set this parameter to No, the dual-point relay control database (Trip/Close)

is overlaid on the DNP Binary Output database of the module. Each DNP point index sent will have an offset of point index times 2 into the database. The first bit of the dual-point relay control database will correspond to the close relay and the second will correspond to the trip relay.

The bit definitions from control byte of CROB are as follows:

 00 - Null (single bit control or select of Trip/Close  01 - Close relay  10 - Trip relay  11 - Invalid

Configuring the MVI69-DNPSNET Module MVI69-DNPSNET ♦ CompactLogix or MicroLogix Platform Distributed Network Protocol Interface Module

If the operate command is used with the Null relay (00), the module will operate on the point as single point control. The following table describes the module's behavior:

Point Index in Command Point in Database Controlled

0 Bit 0 in BO database 10 Bit 10 in BO database 15 Bit 15 in BO database

If the operate command is used with the close relay selected, the module will operate on the first bit of the two database bits associated with the point. The following table describes the module's behavior when the close relay is selected:

Point Index in Command Point in Database Controlled

0 Bit 0 in BO database 1 Bit 2 in BO database 10 Bit 20 in BO database 15 Bit 30 in BO database

If the operate command is used with the trip relay selected, the module will operate on the second bit of the two database bits associated with the point. The following table describes the module's behavior when the trip relay is selected:

Point Index in Command Point in Database Controlled

0 Bit 1 in BO database 1 Bit 3 in BO database 10 Bit 21 in BO database 15 Bit 31 in BO database

It is important to note that the trip and close relays are linked in the module. If a latch-on command is sent to the close relay its bit will be set and the associated trip relay bit will be cleared.

Because the single-point and dual-point control database share the same memory area, caution should be exercised to prevent control of one area by another. This can be accomplished by careful design of the system. The dualpoint database could be isolated from the single-point database. For example, DNP point index 0 to 9 could be used for the dual-point database and correspond to bits 0 to 19. The single-point control points would then start at DNP point index 20 which corresponds to bit 20 of the database.

Using this technique, the MVI69-DNPSNET module will not require any configuration for the new dual-point control, and the module will be backward compatible for current customer applications.

Ladder Logic MVI69-DNPSNET ♦ CompactLogix or MicroLogix Platform Distributed Network Protocol Interface Module

3 Ladder Logic

In This Chapter

 Module Data Objects.............................................................................37

 Adding the Module to an Existing CompactLogix Project......................41

 Adding the Module to an Existing MicroLogix Project............................45

Ladder logic is required for application of the MVI69-DNPSNET 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 Module Data Objects

All data related to the MVI69-DNPSNET is stored in one user defined data type, containing data transfer and status data, and the DNP datasets. Any time an array's size is altered in the RSLogix 5000 software, all the data in the object can be set to zero. Because the array sizes may need to be adjusted for the data types in an application, the user defined data should be adjusted prior to the module being placed in service (if the default configuration does not contain enough data points for the application).

An instance of each data type is required before the module can be used. This is accomplished by declaring variables of the data types in the Controller Tags Edit Tags dialog box. Each object is discussed in the following topics.

3.1.1 DNPModuleDef Object

The DNPModuleDef object contains all the MVI69-DNPSNET module status data and data transfer variables. The object has the following structure.

Name Data Type Description

Status DNPSlvStat Data DNPData CMDcontrolbits DNPCMDBits ReadClock DNPClock WriteClock DNPClock BI_Events DNPBIEvntBlk AI_Events DNPAIEvntBLK BP DNPBackplane

ProSoft Technology, Inc. Page 37 of 119 November 3, 2008

MVI69-DNPSNET ♦ CompactLogix or MicroLogix Platform Ladder Logic Distributed Network Protocol Interface Module

Each of these object types are discussed in the following topics:

DNPSlvStat

This object holds the module status information transferred with each read data block transferred from the module. The structure of the object is shown in the following example:

Name Data Type Description

Scan_Cnt INT Program Scan Counter Product_Name SINT[4] Product Code Rev_Level SINT[4] Revision Op_Sys SINT[4] Operating system revision Run_Number SINT[4] Run number Blk_Rd_Count INT Number of block read transfers Blk_Wr_Count INT Number of block write transfers Blk_Parse_Cnt INT Number of blocks parsed by module Blk_Err INT Number of block errors Rx_Frames INT Number of frames received for this unit Tx_Frames INT Number of frames transmitted for this unit Rx_Total INT Number of frames received Sync_err INT Sync error count Overrun_err INT Overrun error count len_err INT Length error count CRC_err INT CRC error count Overflow_err INT Overflow error count Seq_err INT Sequence error count Addrs_err INT Address error count BI_Events INT Number of binary events generated BI_Queue INT Number of binar y events in q ueue AI_Events INT Number of analog input events AI_Queue INT Number of analog input events in queue FL_Queue INT Float Input Event Count in Buffer Reserved INT Reserved Bad_func_err INT Number of bad function code error count Ukn_Obj_err INT Unknown Object error count Range_err INT Range error count App_Overflow INT Number of application level overflow errors Multi_Frame_err INT Multi-frame error count UDP_Rx_Count INT UDP Recieve Count UDP_Tx_Count INT UDP transmit Count Unsol_error INT Unsolicited Error Count State_Value INT State Value TCP_ST_value INT TCP Socket State Value

This information is important as it can be used to view the "health" of the module. If the module is not communicating, examine the object to help find the problem. Additionally, you should use the configuration/debug port on the module to confirm that the desired configuration of the module is implemented.

DNPBackplane Object

The DNPBackplane Object stores the variables required for backplane data transfer between the module and the processor. The structure of the object is displayed in the following example:

Name Data Type Description

BlockTransferSize INT LastRead INT Index of last read block LastWrite INT Index of last write block BlockIndex INT Computed block offset for data table ReadData INT[240] Buffer File for data Read from Module WriteData INT[240] Buffer File for data Write from Module.

3.1.2 DNPData Object

The DNPData object stores all the data for an MVI69-DNPSNET module. Contained within the object is an array for each data type. The array sizes are set to match the configuration set for the module. If multiple MVI69-DNPSNET modules are used within a rack, a copy of this structure may have to be made to permit each module to have its own database sizes. Ladder logic is required to transfer the data in this structure between the module and the processor. The structure of the object is shown in the following example:

Name Data Type Description

DNP_BI INT[20] Number of DNP BI data words DNP_AI INT[40] Number of DNP AI data words DNP_FLTI REAL[20] Number of DNP Float Input Points DNP_Cntr DINT[10] Number of DNP counter double-words DNP_BO INT[40] Number of DNP BO data words DNP_AO INT[40] Number of DNP AO data words DNP_FLTO REAL[20] Number of DNP Float Output points

3.1.3 Special Objects

These objects utilize some of the advanced features the module provides. If your application does not require the object, then you need not declare an instance of the object. Each of the objects and associated function are discussed in the following topics.

DNP_BI_Event Object

The DNP_BI_Event object stores the information for eleven binary input events to be sent from the processor to the module in a command block 9958. The structure shown in the following example contains all the parameters required for binary input events.

Name Data Type Description

Diagnostics and Troubleshooting MVI69-DNPSNET ♦ CompactLogix or MicroLogix Platform Distributed Network Protocol Interface Module

4 Diagnostics and Troubleshooting

In This Chapter

 Reading Status Data from the Module ..................................................47

 LED Status Indicators............................................................................58

The module provides information on diagnostics and troubleshooting in the following forms:

 Status data values are transferred from the module to the processor.  Data contained in the module can be viewed through the

Configuration/Debug port attached to a terminal emulator.

 LED status indicators on the front of the module provide information on the

module's status.

4.1 Reading Status Data from the Module

The MVI69-DNPSNET module provides the status data in each read block. This data can also be located in the module's database. For a complete listing of the status data object, refer to the Module Set Up section.

4.1.1 Required Hardware

You can connect directly from your computer's serial port to the serial port on the module to view configuration information, perform maintenance, and send (upload) or receive (download) configuration files.

ProSoft Technology recommends the following minimum hardware to connect your computer to the module:

 80486 based processor (Pentium preferred)  1 megabyte of memory  At least one UART hardware-based serial communications port available.

USB-based virtual UART systems (USB to serial port adapters) often do not function reliably, especially during binary file transfers, such as when uploading/downloading configuration files or module firmware upgrades.

 A null modem serial cable.

4.1.2 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.

ProSoft Technology, Inc. Page 47 of 119 November 3, 2008

MVI69-DNPSNET ♦ CompactLogix or MicroLogix Platform Diagnostics and Troubleshooting Distributed Network Protocol Interface Module

5.2 Functional Overview

This section provides an overview of how the MVI69-DNPSNET module transfers data using the DNPSNET protocol. You should understand the important concepts in this chapter before you begin installing and configuring the module.

The DNPSNET protocol driver exists as a single service port (DNPSNET port

20000) implementation that supports a single TCP port connection and multiple UDP ports on a TCP/IP Ethernet network. The DNPSNET port operates as a server, supporting the DNP 3.0 protocol in a Level 2 implementation using the DNP User Group recommended extension for use on LAN/WAN. This is published in "Transporting DNP V3.00 over Local and Wide Area Networks", December 15, 1998 by the DNP Users Group and is available on the Internet at http://www.dnp.org.

5.2.1 General Concepts

The following discussion explains several concepts that are important for understanding the operation of the MVI69-DNPSNET module.

Module Power Up

On power up the module begins performing the following logical functions:

1 Initialize hardware components 2 Install packet driver for Ethernet network interface and TCP/IP stack

o Initialize CompactLogix or MicroLogix backplane driver o Test and clear all RAM o Initialize the serial communication ports

3 Read configuration file from Compact Flash Disk 4 Enable Slave Driver

After the module has received the configuration, the module will begin communicating with other nodes on the network, depending on the configuration.

ProSoft Technology, Inc. Page 65 of 119 November 3, 2008

MVI69-DNPSNET ♦ CompactLogix or MicroLogix Platform Reference Distributed Network Protocol Interface Module

Main Logic Loop

Upon completing the power up configuration process, the module enters an infinite loop that performs the functions shown in the following diagram.

Backplane Data Transfer

The MVI69-DNPSNET module communicates directly over the CompactLogix or MicroLogix backplane. Data is paged between the module and the CompactLogix or MicroLogix 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 can be set to 62, 122 or 242 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 can be set to 61, 121 or 241 words. This large data area permits fast throughput of data from the processor to the module.

The following illustration shows the data transfer method used to move data between the CompactLogix or MicroLogix processor, the MVI69-DNPSNET module and the DNP 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 CompactLogix or MicroLogix 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 databases. These databases are defined as a virtual DNP data tables with addresses from 0 to the maximum number of points for each data type. The following illustration shows the layout of the databases:

MVI69-DNPSNET ♦ CompactLogix or MicroLogix Platform Reference Distributed Network Protocol Interface Module

Data contained in this database is paged through the input and output images by coordination of the CompactLogix or MicroLogix ladder logic and the MVI69DNPSNET module's program. Up to 248 words of data can be transferred from the module to the processor at a time. Up to 247 words of data can be transferred from the processor to the module.

Each block transferred from the module to the processor or from the processor to the module contains a block identification code that describes the content of the block.

The following table defines the blocks used by this module:

Block Number Function/Description

0 or -1 Dummy Blocks : Used by module when no data is to be transferred 1 to 150 DNP Data blocks 1000 to 1149 Output initialization blocks 9250 Status Data Block 9958 PLC Binary Input Event data 9959 PLC Ana log Input Event Data 9970 Set PLC time using module's DNP time 9971 Set module's time using PLC time 9998 W arm Boot Request from PLC (Block contains no data) 9999 Cold Boot Request from PLC (Block contains no data)

Blocks 1 to 150 transfer data between the module and the processor. Blocks 1000 to 1149 are utilized to transfer the initial output databases (binary and analog output data) from the processor to the module at startup. Blocks 9958 to 9999 are used for command control of the module. Each group of blocks are discussed in the following topics.

Normal Data Transfer

Normal data transfer includes the paging of the user data found in the module's internal databases between the module and the controller. These data are transferred through read (input image) and write (output image) blocks. Refer to the Module Set Up section for a description of the data objects used with the blocks and the ladder logic required. Each data block transferred between the module and the processor has a specific block identification code that defines the data set contained in the block. The following illustration shows the direction of movement of the DNP data types between the module and the processor:

Read Block

These blocks of data transfer information from the module to the CompactLogix processor. The structure of the input image used to transfer this data is shown below:

Offset Description

0 Read Block ID 1 Write Block ID 2 to n Read Data

where n = 60, 120, or 240 depending on the Block Transfer Size parameter (refer to the configuration file).

The Read Block ID is an index value used to determine the location of where the data will be placed in the CompactLogix or MicroLogix processor controller tag array of module read data. The number of data words per transfer depends on the configured Block Transfer Size parameter in the configuration file (possible values are 60, 120, or 240).

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

R1W1

R2W2 R3W1 R1W2 R2W1 R3W2 R1W1

This sequence will continue until interrupted by other write block numbers sent by the controller or by a command request from a node on the DNP network or operator control through the module's Configuration/Debug port.

The following example shows a typical backplane communication application.

Note: This example for reference only

Assume that the backplane parameters are configured as follows:

Read Register Start: 0 Read Register Count: 480 Write Register Start: 480 Write Register Count: 480

The backplane communication would be configured as follows:

ProSoft Technology, Inc. Page 69 of 119 November 3, 2008

MVI69-DNPSNET ♦ CompactLogix or MicroLogix Platform Reference Distributed Network Protocol Interface Module

Database address 0 to 479 will be continuously transferred from the module to the processor. Database address 480 to 959 will continuously be transferred from the processor to the module.

The Block Transfer Size parameter basically configures how the Read Data and Write Data areas are broken down into data blocks (60, 120, or 240).

If Block Transfer Size = 60:

How Data is Transferred

In order to understand how the data is transferred between the processor and the module, you must understand the Read Data and Write Data area concept in the module's database. The module's database can be partially, or totally divided into Read Data Areas and Write Data Areas.

These areas are defined by the user when the configuration file is being edited. The following parameters define the Read and Write data areas:

Read Register Start = 0 Read Register Count = 120 Write Register Start = 200 Write Register Count = 120

Each area is broken down into blocks of 60 words. Therefore, the Read Register Count and Write Register Count parameters should be multiples of 60.

The Read Data Area will be transferred from the module to the CompactLogix or MicroLogix processor. The Write Data Area will be transferred from the CompactLogix or MicroLogix processor to the module.

The following example shows the resulting data flow:

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 several command control blocks each of which is discussed in the following topics:

Block 9958 - Processor Binary Input Event

If the processor sends a block 9958, the module will place the binary input event data in the block into the event buffer and alter the data values for the points in the DNP binary input database. The format for the message is shown in the following table.

Data Flow Between MVI69-DNPSNET Module and the CompactLogix or MicroLogix Processor

The following topics describe the flow of data between the two pieces of hardware (CompactLogix or MicroLogix processor and MVI69-DNPSNET module) and other nodes on the DNP network. The DNP Server Driver allows the MVI69-DNPSNET module to respond to data read and write commands issued by a master on the DNP network. The following flow chart and associated table describe the flow of data into and out of the module.

Step Description

The configuration information for the module is retrieved from the DNPSNET.CFG file on the Compact Flash Disk. This information configures the module and define the Ethernet node characteristics.

A Host device (DNP Master unit) issues a read or write command to the module's node address. The driver qualifies the message before accepting it into the module.

After the module accepts the command, the data is immediately transferred to or from the appropriate internal database in the module. If the command is a read command, the data is read out of the database and a response message is built. If the command is a write command, the data is written directly into the database and a response message is built.

Step Description

After the data processing has been completed in Step 3, the response is issued to the originating master node.

Counters are available in the Status Block that permit the ladder logic program to determine the level of activity of the Slave Driver.

The module constantly monitors for command control blocks from the processor. If a valid block is received, the function is executed. Additionally, data is constantly being exchanged between the module and the processor.

Review the Module Configuration section for a complete list of the parameters that must be defined for a slave port.

5.3 MVI69-DNPSNET Application Design

This documentation describes the MVI69-DNPSNET module configuration and setup as it applies to application design. Before attempting to implement this module with a DNP network, verify that the whole design of the system is complete. This includes definition of all the data types and point counts required for each type, all communication parameters required for the network including media type and the use of advanced features such as unsolicited messaging. These must be defined for all master and slave devices on the network. Additionally, the DNP Device Profiles and DNP Subset Definition documents for each device must be reviewed to make sure all the devices will interact on the network as expected. Failure to fully understand these important documents for all devices on the network will usually lead to many problems when implementing the design.

It is important to fully understand the DNP specification as outlined in the Basic Four Documents. These are available to users of the DNP users group. It is recommended that all users of the module have access to these important documents as they define the DNP data types, functions and variations. It will be very difficult to implement the module without an understanding of the protocol and the rules that are defined in the specification. Additionally, potential users should review the DNP Subset and Conformance Test documents and the document that discusses DNP protocol support on Ethernet using the UDP and TCP protocols. These documents provide auxiliary information on the protocol. All of these documents are available to members of the DNP User Group at http://www.dnp.org (http://www.dnp.org). Please check this site for other important information regarding the DNP protocol.

In order to implement a solution using the module, the CompactLogix or MicroLogix processor must be set up using predefined user data structures. The data transfer interface requires ladder logic in order to interface data in the module with that in the processor. The program required for data transfer is developed in ladder and is discussed in the Module Set Up section. This program will interact with the module by sending and receiving data and issuing special control commands.

MVI69-DNPSNET ♦ CompactLogix or MicroLogix Platform Reference Distributed Network Protocol Interface Module

Data tags in the CompactLogix or MicroLogix processor contain the data to be used by the module and the configuration information is stored in the text file, DNPSNET.CFG, stored on the module's Compact Flash Disk. Before you generate the program or layout the data files, you must first design your system. Time spent doing system design at the outset of the project will greatly enhance the success and ease of development of the project.

5.3.1 Designing the system

System design defines the data requirements of the system, communication parameters, and module functionality. The application developer should refer to the person responsible for the DNP master and slave device configurations to verify that the functionality and data types required for the whole system are consistent. Review the DNP Device Profile and DNP Subset documentation for a definition of the level of DNP support offered by the module.

The following topics describe each element of system design.

Data Requirements

This phase of design defines what data elements are to be interfaced in the CompactLogix or MicroLogix processor with the DNP master. The module provides the following data types: digital input, digital output, counter, analog input, analog output, float input and float output. All communications between the DNP master and the PLC is through these data types. Therefore, all data to be used by the system must be contained and configured in one of these data types.

The following illustration shows the databases maintained by the module for the DNP data.

FROZEN DATA FROZEN COUNTER DATA LAST VALUE DATA

The following illustration shows the interaction of the binary and analog input points with the databases.

All data for these data types is derived from the processor and is passed to the module over the backplane. The module will constantly monitor for changes in this data and generate event messages when point values change. For binary input points, events will be generated on any state change. For analog input points, events will be generated for points that have a current value outside of the user-set deadband based on the last value used for an event.

The following illustration shows the interaction of the counter points with the databases.

This data is constantly sourced from the processor and placed in the module's internal database. This information is available to the remote master for monitoring. When the module receives a freeze command from the master unit, it will copy the current counter values into the frozen counter database area. The remote master can then monitor this information. If the module receives a counter freeze with reset command, the current counter values will be passed to the frozen counter database and only the module's values will be set to 0.

Note:This data is not sent to the controller, and the zero data be overwritten by the counter data

contained in the controller. Therefore, the freeze with reset should not be used with this module. The results will not be as expected. There is no way to guarantee that counts will not be lost during the reset step in the module and controller. As a result, this feature was not implemented in the module.

The following illustration shows the interaction of the binary, analog and Float output points with the databases.

MVI69-DNPSNET ♦ CompactLogix or MicroLogix Platform Reference Distributed Network Protocol Interface Module

Output data is sourced from the controlling master station and passed to the processor over backplane from the module. These data are used in the ladder logic to control operations and I/O in the processor.

Data Transfer Interface

Data is transferred between the CompactLogix or MicroLogix processor and the module using module's I/O images. Each block transfer operation transfers up to a maximum of 240 words of data if Block size of 240 is used. The other words in the block contain block header identification codes, or not used. The module defines the blocks to be transferred between the PLC and the module when the system is initialized. For the PLC read operations, word 0 of the module's input image identifies the data set contained in the image. Word 1 contains the block index the module is requesting the processor to write. The PLC constructs the write image to send to the module in the module's output image. The first word of the block identifies the data set contained in the block.

The module determines the block numbers required based on the module read and write register counts defined in the configuration file. The user is responsible for defining these parameters and the starting location of these data areas in the module's database correctly. These data must correspond to the DNP database definitions defined. The module stores the data in fixed order for the data types. The size of each data area for each type is determined by the user configuration. An example is given in the following table.

4 64 4 120 to 123

52 52 52 124 to 175

20 20 40 176 to 215

For the example above, 120 registers will be transferred from the processor (all the input data) and 96 registers will be transferred to the processor (all the output data). The data transfer parameters should be defined as follows:

Parameter Value

Write Register Start: 120 Write Register Count: 96 Read Register Start: 0 Read Register Count: 120

The configuration above will require one block to read and one block to write all the DNP data between the module and the processor.

Reference MVI69-DNPSNET ♦ CompactLogix or MicroLogix Platform Distributed Network Protocol Interface Module

Note that in one block, one or more data types may be transferred. This is especially important when considering the counter and Float data. They require two registers to store their value. The value of a counter should never be passed in two separate blocks. To avoid this potential problem, always configure the module to have the counter data start on an even word number same rule applies to Float points.

The following figure displays the direction of movement of the DNP database data between the module and the processor.

It is important to understand the relationship of the block identifications and the data in the module. Confident data handling in the module is only accomplished if the user defines a consistent set of parameters in the module configuration, handles the read and write operations for the blocks in the module in the PLC ladder logic and understands the requirements of the DNP master unit.

The Reference chapter contains forms to aid in designing your system. They can be used to document the relationship between the point assignments, block identification numbers and the PLC file and offset values and to define the program configuration. Use these forms during your design phase.

DNP Digital Input Data

This data type stores the binary value of 1 or 0. The size of this data area is determined from the configuration parameter Binary Inputs (number of words, each containing 16 binary input points). These data are transferred to the module from the PLC using the read operation. Therefore, these data are read-only for the module and the DNP master unit communicating with the module. When the module receives a new block of this data from the PLC, it compares the new values to those currently in the database. If there is a change in any of the data, the module will generate an event message for the points that change.

The remote DNP master unit can read the current status data and the event data from the module. Event messages generated by the module can be retrieved using a poll for Class 2 data, as all digital input events are considered a Class 2 data type. If unsolicited message generation is enabled in the application, the events will automatically be sent by the module to the DNP master unit when the maximum event count for Class 2 data is reached or when the timeout for unsolicited messages is exceeded. A data flow diagram for the digital input data is shown in the following figure.

DNP Digital Output Data

This data type stores digital control and command state data received from the DNP master unit with a value of 1 or 0. The size of this data area is determined from the configuration parameter Binary Outputs (defines number of words, each containing 16 binary output points). These data are transferred from the module to the PLC using the write operation. Therefore, these data are read-only for the PLC, as the PLC cannot directly alter these values in module. It is the responsibility of the DNP master unit to maintain this data. For example, if the DNP master sets a digital point on, it will remain on until the master resets the point. A data flow diagram for the digital output data is shown in the following figure.

DNP Counter Data

This data type stores accumulated count data. These data are stored in the module in a double word value and have a data range of 0 to 4,294,967,296. The size of this data area is determined from the configuration parameter Counters. The PLC transfers data of this type to the module using the read operation. The module maintains two values for each counter point: a current running value and a frozen value. The DNP master must send the freeze command to the module in order to transfer the current running values to the frozen area.

Note: The freeze-reset command is not supported in the data transfer operation. There is no way

to guarantee counts will not be lost using the freeze-reset operation, therefore, this feature is not implemented.

DNP Analog Input Data

This data type stores analog data with a data range of 0 to 65535 or -32768 to

32767. The size of this data area is determined from the configuration parameter Analog Inputs. These data are transferred to the module from the PLC using the read operation. Therefore, these data are read-only for the module and the DNP master unit. When the module receives a new block of this data from the PLC, it compares the new values to those currently in the database. If there is a change in any of the data, the module will generate an event message for the points that change. The dead-band parameter configured for the module determines the variance required for the event message.

The DNP master unit can read the current value data and the event data from the module. Event messages generated by the module can be retrieved using a poll for Class 3 data, as all analog input events are considered a Class 3 data type. If unsolicited message generation is enabled in the application, the events will automatically be sent by the module to the DNP master unit when the maximum event count for Class 3 data is reached or when the timeout for unsolicited messages is exceeded. A data flow diagram for the analog input data is shown in the following figure.

DNP Analog Output Data

This data type stores analog values sent from the DNP master unit to the module and PLC with a data range of 0 to 65535 or -32768 to 32767. The size of this data area is determined from the configuration parameter Analog Outputs. These data are transferred from the module to the PLC using the write operation. Therefore, these data are read-only for the PLC, as the PLC cannot directly alter these values in the module. It is the responsibility of the DNP master unit to maintain this data. For example, if the DNP master sends a value of 3405 to the module for a specific point, the value will be stored in the module until changed by the master. A data flow diagram for the analog output data is shown in the following figure.

DNP Float Input Data

This data type stores float data. The size of this data area is determined from the configuration parameter float Inputs. These data are transferred to the module from the PLC using the read operation. Therefore, these data are read-only for the module and the DNP master unit. When the module receives a new block of this data from the PLC, it compares the new values to those currently in the database. If there is a change in any of the data, the module will generate an event message for the points that change. The dead-band parameter configured for the module determines the variance required for the event message.

The DNP master unit can read the current value data and the event data from the module. Event messages generated by the module can be retrieved using a poll for Class 3 data, as all float input events are considered a Class 3 data type. If unsolicited message generation is enabled in the application, the events will automatically be sent by the module to the DNP master unit when the maximum event count for Class 3 data is reached or when the timeout for unsolicited messages is exceeded. A data flow diagram for the float input data is shown in the following figure.

5.3.2 Communication Parameters

This phase of design defines the communication parameters required for successful communications between the module and DNP master and slave units over the Ethernet network. Determine the IP address for the module and the list of IP addresses that can connect to the unit if this feature is enabled. Consult with the MIS person in charge of assigning these addresses and setting up the network configuration. The Reference chapter contains a form to aid in setting these parameters. Fill out this form before attempting to configure the module. You must also determine if the UDP or the TCP protocol or both will be used in your application. The module supports a single connection for the TCP protocol. The UDP server supports receipt of messages from multiple clients. Access to both servers can be limited by using the IP address list filtering.

5.3.3 Functionality

This phase of design defines the features of the DNP Level 2 Subset supported by the module and to be utilized in the specific application. For example, will the unit use unsolicited messaging? Coordination with the DNP master developer is required to verify that the host will support the functionality you select. The features that must be defined in this design step are as follows:

 Will analog events be returned with or without a time value?  Will events be logged before time synchronization has occurred?  Will the module start with database values initialized by the processor?

For a complete description of the module configuration, refer to the Module Setup section.

5.3.4 Data Transfer at Startup

The module can be configured to have the internal databases initialized with data contained in the processor. This feature requires ladder logic. Data to be initialized are as follows: Binary and Analog Output data. This feature can be used to bring the module to a known state (last state set in controller) when the module is first initialized. For example, in order to have the module startup using the last set of binary output values and setpoint values (analog outputs), enable this feature.

If this feature is implemented, the module will request the data from the processor. Ladder logic must handle the blocks requested by the module (1000 to 1149) based on the modules configuration values for the write block data. When the block is requested, the module must place the correct data in the block and return the block to the module. The module will receive the data and initialize the output values. Each block required by the module for initialization will be requested.

5.3.5 Module Operation

After the system has been designed and the system is set up, the module will be ready to operate. When the module is first initialized, it will read the configuration file (DNPSNET.CFG on the module's Compact Flash Disk). After the file is processed, the module will use the data to set up the data structures of the application. If any errors are encountered during the initialization process, the default value for the parameter will be assigned and used.

The module will next check if the output initialization feature is utilized. The option permits the PLC to set these read-only data at startup. There is no static memory available on the module to remember the last values for these data types. In order to prevent a "shock" to the system at boot time, this option can be used to set the module's database to the last transferred set of data. If this option is enabled, the module will request the binary and analog output from the PLC. This is done using blocks 1000 to 1149. Ladder logic must transfer the data for this feature to operate.

After the successful initialization of the module, the program will start the normal data transfer between the module and the CompactLogix or MicroLogix processor. The program will send a read block first and then wait for a write block to receive data from the PLC. This alternating sequence of read and write will continue as long as the program is running. The program will update the DNP memory areas in the module with the new data and generate events for digital and analog input status changes.

If the module is configured for unsolicited messaging, the module will immediately send an unsolicited response once the remote master connects to the module, informing the master of a module restart. The module will not log events or process any data read operations from the master until the master clears the restart IIN data bit. The master must also synchronize the time with the module before events will be generated if the module is so configured. The master is also responsible for enabling the unsolicited message facility in the module by sending the Enable Unsolicited Messaging command to the module.

If the module is not configured for unsolicited messaging, the DNP master must clear the restart IIN bit before the module will start logging events. The master must also synchronize the time with the module before events will be generated if the module is so configured.

Additionally, the program will listen on Port 1 for requests. This is the debug port for the module and transfers module information to an attached terminal. Refer to the Diagnostics and Troubleshooting section for a complete discussion on the use of this important feature.

5.4 Cable Connections

The MVI69-DNPSNET module has the following communication connections on the module:

 One Ethernet port (RJ45 connector)  One RS-232 Configuration/Debug port (RJ45 connector)

5.4.1 Ethernet Connection

The MVI69-DNPSNET module has an RJ45 port located on the front of the module labeled "Ethernet", for use with the TCP/IP network. The module is connected to the Ethernet network using an Ethernet cable between the module's Ethernet port and an Ethernet switch or hub.

Note: Depending on hardware configuration, you may see more than one RJ45 port on the

module. The Ethernet port is labeled "Ethernet".

Warning: The MVI69-DNPSNET module is NOT compatible with Power Over Ethernet

(IEEE802.3af / IEEE802.3at) networks. Do NOT connect the module to Ethernet devices, hubs, switches or networks that supply AC or DC power over the Ethernet cable. Failure to observe this precaution may result in damage to hardware, or injury to personnel.

Important: The module requires a static (fixed) IP address that is not shared with any other device

on the Ethernet network. Obtain a list of suitable IP addresses from your network administrator BEFORE configuring the Ethernet port on this module.

Ethernet Port Configuration - wattcp.cfg

The wattcp.cfg file must be set up properly in order to use a TCP/IP network connection. You can view the current network configuration using an ASCII terminal by selecting "@" (Network Menu) and "V" (View) options when connected to the Debug port.

# WATTCP.CFG FILE: # ProSoft Technology. my_ip=192.168.0.100 # Default class 3 network mask netmask=255.255.255.0 # The gateway I wish to use gateway=192.168.0.1

5.4.2 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:

Disabling the RSLinx Driver for the Com Port on the PC

The communication port driver in RSLinx can occasionally prevent other applications from using the PC's COM port. If you are not able to connect to the module's configuration/debug port using ProSoft Configuration Builder (PCB), HyperTerminal or another terminal emulator, follow these steps to disable the RSLinx Driver.

1 Open RSLinx and go to Communications>RSWho 2 Make sure that you are not actively browsing using the driver that you wish to

stop. The following shows an actively browsed network:

3 Notice how the DF1 driver is opened, and the driver is looking for a processor

on node 1. If the network is being browsed, then you will not be able to stop this driver. To stop the driver your RSWho screen should look like this:

4 When you have verified that the driver is not being browsed, go to

Communications>Configure Drivers

You may see something like this:

If you see the status as running, you will not be able to use this com port for anything other than communication to the processor. To stop the driver press the "Stop" on the side of the window:

5 After you have stopped the driver you will see the following:

6 Upon seeing this, you may now use that com port to connect to the debug

port of the module.

Note: You may need to shut down and restart your PC before it will allow you to stop the driver

(usually only on Windows NT machines). If you have followed all of the above steps, and it will not stop the driver, then make sure you do not have RSLogix open. If RSLogix is not open, and you still cannot stop the driver, then reboot your PC.
