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.

2.7 [IEC-103 Master Commands]

This section can contain up to 1000 user defined commands to be executed by the module and sent to the controlled devices. There is no need to place Class 1 or Class 2 polls in the this list for the controlled devices as the master driver for each port will execute these automatically when the port is idle. In order for the port to be idle, make sure that there is idle time available, and that the commands do not constantly utilize the ports. The command list section starts with a reserved label START and ends with the label END. Each row in the file corresponds to an individual command with the first character position in each row left blank (white space).

As an alternative to using a command list, blocks with an identification code of 9901 can be used to issue commands from the ladder logic.

2.7.1 Enable Code

0 = Disabled 1 = Enabled with Poll Interval (seconds) utilized 2 = Conditional (executed when point in database changes) This field defines whether or not the command is to be executed and under what

conditions. If the parameter is set to 0, the command is disabled and will not be executed in the normal polling sequence. The command can be executed under the control of the PLC processor through the use of a Command Control block. Setting the parameter to a value of 1 for the command causes the command to be executed each scan of the command list if the Poll Interval Time is set to zero. If the Poll Interval time is set, the command will be executed, when the interval timer expires. If the parameter is set to 2, the command will execute only if the internal data associated with the command changes. This value is valid only for write commands.

2.7.2 Database Index

Database Index is the location in the module's database to use as the source for the data in the command. The data type field determines the meaning of the index as follows:

Type Description DB Index type

6 Clock synchronization NA 7 General interrogation NA 20 General Command Bit address

2.7.3 Poll Interval

This parameter specifies the minimum frequency at which the module should execute the command. The value is entered in units of seconds. For example, to execute a command every 10 seconds, enter a value of 10 in the field. A value of 0 for the parameter implies that the command should be executed every scan of the list.

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

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

 Adding the Module to an Existing MicroLogix Project............................49

Ladder logic is required for application of the MVI69-103M 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

This section describes the controller tags that are defined in the example logic to interface with the module. The user can extend these tags to meet the specifications required for their application.

3.1.1 Module Status Data and Variables (MVI69103M_ModuleDef)

All status and variable data related to the MVI69-103M is stored in a user-defined data type. An instance of the data type is required before the module can be used. This is done by declaring a variable of the data type in the Controller Tags Edit Tags dialog box. The structure of the object is displayed in the following example:

Tag Type Data Type Description

DATA MV69103M_DATA Stores data point values CONTROL MVI69103M_CONTROL Optional block handling STATUS MVI69103M_STATUS Stores module status UTIL MVI69103M_UTIL

The other members of the object are be utilized in the ladder logic to assist in the data transfer operation.

3.1.3 Data Object (MV69103M_DATA)

Data for the module is stored in two controller tags for the example ladder logic. The read data (data transferred from the module to the processor) is stored in the controller tag MVI69103M.DATA.ReadData[ ]. The write data (data transferred from the processor to the module) is stored in the controller tag MVI69103M.DATA.WriteData[ ]. Separate tags can be constructed for each data type utilized by the controlled devices and for each device.

3.1.4 User Command Data Object (MVI69103M_UserCommand)

User Command is an optional feature that allows the processor to dynamically build commands, instead of using the configured commands from the configuration file.

In order to support the user command control of the module, refer to MVI69103M.CONTROL.UserCommand.Activate to trigger the block. The tag MVI69103M.CONTROL.UserCommand.Count sets the number of commands to be sent (maximum of 5 per block). Use the tag MVI69103M.CONTROL.UserCommand.UserCommand to set the commands. The structure of this object is shown in the following figure:

Data Type Description

DBIndex Address in module's database to associate with command Session Session Index Sector Sector Index DataType ASDU data type for command FunctionCode Function code InformationNumber Information object address of the point OverrideFlag Override flag used with ASDU 20 (0=use db value, 1=use override) OverrideValue Override value to use if override flag set

Refer to the Command List section of this document for the definition of each of the parameters. This option permits execution of user-generated commands from the ladder logic directly to controlled devices. This feature is especially important in generating general commands (ASDU 20 object) request.

Ladder Logic MVI69-103M ♦ CompactLogix or MicroLogix Platform IEC 60870-5-103 Master Communication Module

When the command bit (MVI69103M.CONTROL.UserCommand.Activate) is set, the module will build the block 9902 in the output image. The module will receive the new block and place the commands into the command queue for execution.

3.1.6 Event Message Data Object (MVI69103M_Event)

The module can be configured to pass event messages received from the controlled devices to the processor. Refer to the Pass-Through Events (page 24) parameter for further information about this feature. The module sends this information to the processor in read blocks with identification codes of 9903. The example ladder logic has a data structure that conforms to the data structure sent for each element by the module. The following figure displays the object:

Data Type Description

Session Session values Sector Sector values ASDU_Type ASDU type for event message PointIndex Point index Function Function index FaultNumber Fault Number for event (ASDU type 2 and 4 only) Milliseconds Milliseconds Seconds Seconds Minutes Minutes Hour Hour Invalid Valid time flag DST Daylight savings time flag RelativeTime Relative Time (ASDU type 2 and 4 only) Value Value for event received (may want to set float type for ASDU 4)

ProSoft Technology, Inc. Page 43 of 131 November 3, 2008

MVI69-103M ♦ CompactLogix or MicroLogix Platform Ladder Logic IEC 60870-5-103 Master Communication Module

The example ladder logic defines a 5-element array of the MVI69103M_Event objects to hold the data received in a single 9903 block. Ladder logic to handle a 9903 block is shown in the following figure:

This simple logic does not use the message count parameter in the block and will not work for most applications. It is only provided as an example to display how to move the 9903 data to a user controller tag. If the message pass-through feature is utilized, more logic is required to store the messages received. This feature is most commonly utilized to pass events from the controlled device to an event logger connected to the processor.

3.1.7 Data Object (MVI69103M_Clock)

This type is used to copy the date and time information between the MVI and the processor through optional block 9970 and 9971. Please refer to the sample ladder logic (on the ProSoft Solutions CD) for further information about this feature.

4.1.1 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 sub-menus for this module contain commands to redisplay the menu or return to the previous menu. You can always return from a sub-menu to the next higher menu by pressing [M] on your keyboard.

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

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

Keystrokes

The keyboard commands on these menus are almost always non-case sensitive. You can enter most commands in lower case or capital letters.

The menus use a few special characters ([?], [-], [+], [@]) that must be entered exactly as shown. Some of these characters will require you to use the [Shift], [Ctrl] or [Alt] keys to enter them correctly. For example, on US English keyboards, enter the [?] command as [Shift][/].

Also, take care to distinguish capital letter [I] from lower case letter [l] (L) and number [1]; likewise for capital letter [O] and number [0]. Although these characters look nearly the same on the screen, they perform different actions on the module.

5.2.1 General Concepts

The following discussion explains several concepts that are important for understanding the operation of the MVI69-103M module.

Module Power Up

On power up the module begins performing the following logical functions: 1 Initialize hardware components

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

2 Read configuration for module from IEC103M.CFG file on Compact Flash

Disk

3 Initialize the databases and ports 4 Set up the serial communication interface for the debug/configuration port

After the module has received the configuration, the module will begin receiving and transmitting messages with devices on the serial networks.

MVI69-103M ♦ CompactLogix or MicroLogix Platform Reference IEC 60870-5-103 Master Communication Module

Main Logic Loop

Upon completing the power up configuration process, the module enters an infinite loop that performs the following functions:

Backplane Data Transfer

The MVI69-103M module communicates directly over the CompactLogix or MicroLogix backplane. Data travels 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 data is determined by the 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.

Data received by the master drivers is placed in the module's input image. This data is processed by the ladder logic in the CompactLogix or MicroLogix processor.

The processor inserts data in the module's output image to transfer to the module. The module's program extracts the data and transmits the data out to the master driver to the serial network. Additionally, the CompactLogix or MicroLogix processor can send special control blocks to the module to instruct it to perform a special task.

Reference MVI69-103M ♦ CompactLogix or MicroLogix Platform IEC 60870-5-103 Master Communication Module

The following illustration shows the data transfer method used to move data between the CompactLogix or MicroLogix processor, the MVI69-103M module, and the serial 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 defined in the controller tags. The user is responsible for handling and interpreting all data received on the application ports and transferred to the input image.

Data Types and Mapping

When interfacing data in the processor to that of the IEC 60870-5-103 protocol, it is important that the user understand the mapping of the data types to their corresponding representation in the modules database. The following table lists the data types supported by the module and their associated storage representation:

Type ID Description Data Representation

* The words should be swapped in the ladder logic.

Measurands with quality descriptor. The lower 3 bits of the values represented in this data type contain status information. The upper 13 bits of the value contained a signed, 12-bit number. This data type will return from 1 to 4 values. The number of words received is dependant on the information object number and the slave device.

Time-tagged measurands with relative time with the value in the packet represented by a single floating point number.*

Identification data composed of 12 characters of data. Each point in defined of this data type should reserve 12 bytes (6-word addresses) in the database for the data received.

Measurands with quality descriptor. The lower 3 bits of the values represented in this data type contain status information. The upper 13 bits of the value contained a signed, 12-bit number. This data type will return from 1 to 9 values (some slaves may return up to 16 values). The number of words received is dependant on the information object number and the slave device.

General command to control a dualpoint object. Each command issued by the module uses the values of two adjacent bits in the database or an override value specified by the user command.

Measurand with quality descriptor (7.2.6.8) Bit 0: 0 = No overflow, 1 = Overflow Bit 1: 0 = Valid, 1 = Invalid Bit 2: Reserved Bits 3 to 25: Value from -1..+1-2

Short floating-point number stored in IEEE STD 754 format (Fraction, Exponent, Sign) (7.2.6.20)

Byte data as defined in 7.2.6.2. First 8 bytes are characters 1 to 8 and last 4 bytes are manufacture bytes either decimal (0 to 255) or as ASCII characters.

Measurand with quality descriptor (7.2.6.8) Bit 0: 0 = No overflow, 1 = Overflow Bit 1: 0 = Valid, 1 = Invalid Bit 2: Reserved Bits 3 to 25: Value from -1..+1-2

Dual-bit status (7.2.6.4 with 00b (0 decimal) = not used, 01b (1 decimal) = Off, 10b (2 decimal) = On and 11b (3 decimal) = not used

As shown in the previous table, all bit types are addressed as bits in the modules database.

Addressing the Data Types

The following table shows an example of how to address the data types in the MVI69-103M:

Data Type Address Type Length Example

1 Bit 2 bits

2 Bit 2 bits

3 Word 4 words Address 50 refers to word 50, 51, 52, and 53. 4 Double-word 2 words

5 Bit 12 bits

Address 160 refers to first and second bits from word 10.

Address 40 refers to two consecutive words starting at word 80.

Address 180 refers to 12 consecutive bits starting at the LSB of word 90.

Reference MVI69-103M ♦ CompactLogix or MicroLogix Platform IEC 60870-5-103 Master Communication Module

Data Type Address Type Length Example

9 Word 5 words

20 Bit 2 bits

Address 100 refers to 9 consecutive words starting at word 100.

Address 160 refers to the first and second bits from word 10.

Therefore, address 16000 represents bit zero in word 1000 of the module's database. Short floating-point, 32-bit strings and integrated total values each occupy a double-word space in the database. Therefore, short float database address of 100 represents the two words, 200 and 201, in the modules database. Identification objects are stored as byte values in the modules database. Identification object address 1000 is stored in the module's database in word addresses 500 to 505.

When setting the monitored data and commands, each point is defined by its ASDU type, function code, and information number. Valid function codes are listed in the following table.

Function Code Symbol Number

Distance Protection T(z) 128 Over-current Protection I> > 160 Transformer Differential

Protection Line Differential Protection rIl 192 Global Function Type GLB 255

Refer to Protocol Interoperability Documentation for a full listing of the protocol support offered by the module.

As blocks are transferred between the module and the processor, each block contains block identification codes that define the content or function of the block of data transferred. The block identification codes used by the module are displayed in the following table.

Block Range Descriptions

-1 Null block 0 Null block 1 to 20 Read or write data 9901 User Constructed Command 9902 Command Control Block (Add command to Command List Queue) 9903 Event Messages from Master port 9950 Command List Error data 9970 Set PLC time using module's time 9971 Set module's time using CompactLogix or MicroLogix time 9998

MVI69-103M ♦ CompactLogix or MicroLogix Platform Reference IEC 60870-5-103 Master Communication Module

Blocks -1 and 0 transfer status data from the module to the processor and they contain no data when transferred from the processor to the module. Blocks 1 to 20 are utilized to transfer data stored or to be stored in the module's database. These data blocks send data from module to the processor (monitored data received from the devices on the serial network) and to send data from the processor to the module (control data to send to the end devices). Block identification codes 9901 to 9999 are used for special control blocks to control the module.

Normal Data Transfer

Normal data transfer includes the transferring of data received by or to be transmitted to the master drivers and the status data. These data are transferred through read (input image) and write (output image) blocks.

Refer to Module Configuration for a description of the data objects used with the blocks and the ladder logic required. The following topics discuss the structure and function of each block.

Read Block

These blocks of data transfer information from the module to the CompactLogix or MicroLogix processor. The structure of the input image used to transfer this data is shown in the following table.

Offset Description Length

0 Read Block ID 1 1 Write Block ID 1 2 to (n+1) Read Data n

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 103M network or operator control through the module's Configuration/Debug port.

The following example shows a typical backplane communication application. 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:

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:

If Block Transfer Size = 240:

Write Block

These blocks of data transfer information from the CompactLogix or MicroLogix processor to the module. The structure of the output image used to transfer this data is shown in the following table.

Offset Description Length

0 Write Block ID 1 1 to n Write Data n

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

configuration file). The Write Block ID is an index value used to determine the location in the

module's database where the data will be placed.

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:

ProSoft Technology, Inc. Page 81 of 131 November 3, 2008

MVI69-103M ♦ CompactLogix or MicroLogix Platform Reference IEC 60870-5-103 Master Communication Module

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

Block identification codes greater than 9900 are utilized to perform special functions in the module. Each control block recognized and used by the module is defined in the following topics.

User Constructed Command Block (9901)

Block identification code 9901 issues one or more user constructed commands. When the module receives a block 9901 identification code, it will place the included commands into the command queue.

Information object address for the point on which the command operates.

Refer to the command list section of this documentation for a detailed definition of the fields contained in this block. They are the same as those used in constructed the commands in the command list.

There is no response block built by the module to send back to the processor after the block is processed. The commands are placed in the command queue and issued at a high priority.

This block and block 9902 should be used when controlling double-point data points in remote units using general commands. This provides complete control of the slave devices under ladder logic control. Alternatively, the slaves can be controlled by changing data in the database and having the data be transferred using pre-constructed commands in the user's command list. Some points only accept value of on for control (that is, LED reset or activate characteristic). For these points, block 9901 and 9902 should only be utilized.

Command Control Block (9902)

The block 9902 identification code is used by the processor to send a list of commands to be placed in the command queue from the user configured command list. Commands placed in the queue with this method need not have their enable bit set in the command list.

This field contains the number of commands to enable in the command list. Valid values for this field are 1 to 50.

Command Numbers to enable

These 50 words of data contain the command numbers in the command list to enable. The commands in the list will be placed in the command queue for immediate processing by the module. The first command in the list has an index of 0.

There is no response to this block by the module. The module will place the selected commands into the command queue. If the command references a unit that is not defined, the command will not be placed in the command queue. Normal processing of the command list will continue after the commands specified in this block are processed.

For digital output control, the use of block 9901 and 9902 is preferred to the use of the command list. The exact state of the output can be specified in the command list and then the command can be enabled through the use of block

9902. When the user wishes to execute this command (knowing the state of the command), can enable the command with the block 9902 request.

This is the fault number for the event if applicable. Only valid for ASDU types 2 and 4.

This word contains the seconds and millisecond values with a range of 0 to 59999 time at which the message was generated by the slave device.

This word contains the hour and minutes the message was generated by the slave. The MSB contains the hour and the LSB contains the minute value.

This word contains two bits that relate to the time value recorded in the slave device for the message. Bit 0 corresponds to the validity of the time (0=valid, 1=invalid) and Bit 1 defines if daylight savings time is used in the time (0=no, 1=yes).

This field contains the relative time value if applicable to the object. Only valid for ASDU types 2 and 4.

This double-word value contains the value for the point index/function code in the event message. For ASDU types 1 and 2, this value is only 2 bits wide. For ASDU type 4, this double-word value contains the floatingpoint number (short circuit location).

In order for this feature to be activated, the event pass-through parameter must be set. When a master driver receives an event message from a controlled station, it will build an event message corresponding to the event in the event buffer of the module. This buffer is then sent to the processor when any messages are present. Therefore, these blocks are sent to the processor on a high priority. After the block is sent, the event message is removed from the module's event buffer.

If too many events are present in the buffer (>200), the module will set the event message overflow flag in the error/status data area of the normal read data block. There is no response block to be received by the module from the processor.

Command List Error Data Block (9950)
