Battery Life Advisory

The MVI46, MVI56, MVI56E, 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 configuration to match the interface. There are three jumpers located at the bottom of the module.

The following illustration shows the MVI56-103M 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 MVI56-103M 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 MVI56-103M 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

2.1 Configuration File

The MVI56-103M module stores its configuration in a text file called IEC103M.CFG, located in the module's flash memory. When the module starts up, it reads the configuration file and uses the information to control how the 103 protocol interacts with the module's application port(s).

The configuration file is arranged in Sections, with a heading in [ ] characters at the beginning of each section. Each Section contains a list of Parameters and Values, followed by an optional Comment that explains the parameter.

The following illustration shows an example of a Section, a Parameter, a Value, and a Comment.

The Parameter must be followed by a [:] (colon) character. The text following the

[:] is a Value.

The module ignores "comment" text following the [#] character. Use comments to document your configuration settings.

You can get a sample configuration file for the module in the following places:

 Copy the IEC103M.CFG from the module's flash memory to your PC  Copy the IEC103M.CFG from the ProSoft Solutions CD-ROM supplied with

the module

 Download the IEC103M.CFG from the ProSoft Technology web site at

www.prosoft-technology.com

MVI56-103M ♦ ControlLogix Platform Configuring the MVI56-103M Module IEC 60870-5-103 Master Communication Module User Manual

2.2 Quick Start

This section provides the steps required to configure the module. After you download the sample configuration file, please perform the following steps:

Step 1: Configure the Number of Slaves (Sessions)

The IEC 60870-5-103 protocol is a Master-slave protocol where the slaves are typically protection equipments for substations. The MVI56-103M module supports up to 32 slaves (total) connected to its application serial ports. Each slave has to be configured as a session. Refer to the configuration file to enter the number of slaves that will be connected to the MVI56-103M module:

[IEC-870-5-103 Master] Session Count: 5 #1 to 32 - maximum number of slaves on all channels

In the example above, the module will only poll sessions 0 to 4. The module would not poll sessions 5 to 31.

In Step 3, you will configure each session as an actual slave in the network.

Step 2: Configure the Port Communication Parameters

The user should configure the port communication parameters in order to enable data transfer between the Master and the slave(s). The port communication parameters include baud rate, parity, RTS ON, RTS OFF and Minimum Delay. The IEC 60870-5-103 protocol uses two baud rates: 19200 or 9600 kb/s and even parity.

Refer to the [IEC-870-5-103 Master Port 0] section in the configuration file in order to configure the communication parameters for the 103M port:

[IEC-870-5-103 Master Port 0] # Communication Parameters Baud Rate : 19200 #Baud rate for port 9600-19200 Parity : E #N=None, O=Odd, E=Even, M=Mark, S=Space RTS On : 0 #0-65536 mSec before message RTS Off : 1 #0-65536 mSec after message Minimum Delay : 10 #Minimum # of mSec before response sent Receive Timeout: 2000 #Maximum mSec from first char to last to wait # These parameters are protocol specific Single char ACK F0,1 or 3: Y #Single E5 resp to ACK func 0, 1 & 3 req (Y/N)

The user should also configure the jumpers located at the bottom of the module to select the correct electrical interface mode: RS-232, RS-422 or RS-485.

Step 3: Configure the Session (Slave) Poll Parameters

According to the IEC 60870-5-103 protocol, the Master cyclically polls data from the slaves. The data is classified into two classes; Class 1 and Class 2. Events belong to Class 1 and analog data to Class 2. The module can request data through Class 1 or Class 2 requests. Responses to control command and general interrogation commands are also sent as Class 1 data.

Refer to the [IEC-103 Master Session x] section in the configuration file in order to configure how each slave will be polled.

ProSoft Technology, Inc. Page 27 of 152 February 22, 2013

Configuring the MVI56-103M Module MVI56-103M ♦ ControlLogix Platform User Manual IEC 60870-5-103 Master Communication Module

Initially, the user should enter the MVI56-103M port number that will be connected to the session (slave) using the "Communication Port" parameter. Valid values are 0 or 1.

These parameters include the Data Link Address, which is the slave address that identifies all protection equipment on the network. There should be a unique number for each slave on the network. There are also certain parameters that pertain to how the Class 1 and Class 2 polls will be used for data transfer.

You must enter the number of sectors for each session using the Sector Count parameter. The module accepts up to 5 sectors per session.

[IEC-103 Master Session 0] Communication Port : 0 #Index of COM port for session (0 or 1) Sector Count : 5 #5 is max for this version of app Data Link Address : 0 #Range is 0 to 65535 DL address of slave

Failure Delay : 3 #Min Sec to delay before poll of offline slave #(0 to 2000 seconds) Confirm Timeout : 20000 #0 to 4,294,967,295 msec to wait for DL confirm Retry Count : 5 #0 to 255 retries for if no confirm Response Timeout : 5000 #Timeout for confirm of req (0 to 4,294,967,295 msec) C1/C2 Poll Count Pend: 6 #Class 1 or 2 polls before next slave tried (0-

65535) Class 1 Polls : 10 #Max Class 1 polls to this session Class 1 Pend delay : 1000 #Min mSec delay between call (0 to 4,294,967,295 msec) Class 2 Pend delay : 1000 #Min mSec delay between call (0 to 4,294,967,295 msec) Class 1 Poll delay : 1000 #Min mSec delay between call (0 to 4,294,967,295 msec) Class 2 Poll delay : 1000 #Min mSec delay between call (0 to 4,294,967,295 msec)

This step should be repeated for each session to be used. For example, if the user selected 8 sessions during Step 1, he or she should configure sessions 0 to 7:

[IEC-103 Master Session 0] [IEC-103 Master Session 1] [IEC-103 Master Session 2] [IEC-103 Master Session 3] [IEC-103 Master Session 4] [IEC-103 Master Session 5] [IEC-103 Master Session 6] [IEC-103 Master Session 7]

Step 4: Sector (Data Set) Configuration

For each session (slave), you must configure one or more sectors (maximum of

5). A sector is a data set defined by the vendor. Each sector is identified by the Common ASDU Address parameter in the [IEC-103 Master Session x Sector 0] area in the configuration file. This area also contains some parameters that will affect the module initialization procedure.

[IEC-103 Master Session 0 Sector 0] Common ASDU Address : 0 #Range 0 to 255 Sector address

1 128 128 25 1 144 128 26 205 100 133 51 205 100 133 52 END

This step should be repeated for each sector used by the application. The module will only use the sectors configured in the previous step.

Step 5: Monitor Point Configuration (Monitor Direction)

After the slave receives a Class 1 or Class 2 request from the Master, it responds with a message containing data. Each piece of equipment is normally configured to respond with specific points when it is being polled with a Class 2 request. During a Class 2 response, the slave may set a control bit (ACD) to inform the Master that there are new events to be transmitted. Then, the Master will send a Class 1 poll to read the events from the slave.

The IEC 60870-5-103 protocol states that the data is transferred between the Master and slave using an ASDU (Application Service Data Unit) format. Each format is given by:

 Type Identification  Variable Structure Qualifier  Cause Of Transmission  Common Address of ASDU  Function Type  Information Number  Data…

Refer to the protection equipment specification for the following information about each point:

 Type: Type of the message  Function Type: Type of protection function  Information Number: Point Identification

This information will identify each point in the MVI56-103M configuration file. The user has to configure the points that will be updated in the MVI56-103M database when a Class 2 or Class 1 response containing data is sent from the slave. Refer to [IEC-103 Master Session x Sector y] section in the configuration file in order to configure each point:

# ASDU Database Function Point # Type Index Code Index START 1 0 128 16 1 16 128 17 1 32 160 18 1 48 176 19 1 64 192 20 1 80 128 21 END

Where the user should enter:

ASDU Type: ASDU type for the point Function Type: Function type for the point

SIEMENS Meter Data (Private Range) Double-word address for each meter point

IEC 60870-5-103 Master Communication Module User Manual

Point Index: Information number for the point Database Index: The MVI56-103M database location where the value will be

copied. Special attention should be considered since the type of addressing will depend on the ASDU type:

For example, in order to configure the following points:  Time-tagged message point with information number 17 (teleprotection

active) and distance protection function (128). The value will be copied to bits 0 and 1 in word 1 (second word) in the module’s database.

 Measurands I point with information number 144 (measurands I) and

overcurrent protection function (160). The value will be copied to word 50 in the module’s database.

The following configuration information should be entered:

# ASDU Database Function Point # Type Index Code Index START 1 16 128 17 1 50 160 144 END

Every time the module responds with a Class 1 or Class 2 poll with these points, the module will update its value to the database.

All the points configured in this section are sent from the slave to the Master. The protocol specification refers to this data flow as the Monitor Direction.

This step should be repeated for each sector.

Step 6: Command Configuration (Control Direction)

The user might also configure the Master to send commands to slaves. The IEC 60870-5-103 protocol specification refers to this data flow as Control Direction. The commands include general commands, interrogation requests, and time synchronization requests. In order to configure a command, refer to the [IEC-103 Master Commands] section:

[IEC-103 Master Commands] # # Enable code field is as follows: # 0 = Disabled # 1 = Enabled with Poll Interval (seconds) utilized # 2 = Conditional (executed when point in database changes) # # Database Index is the location in the module's database to use as the source

When sending a General Command, the user might associate the source data with a register in the MVI56-103M database to be sent to the remote slave. The following example will send 8 commands to the slave configured as Session 0/Sector 0. When using a General Command, the bit addressing should be used:

# Enable DB Poll Session Sector Data Func Point Ovrd Ovrd # Code Index Interval Index Index Type Code Index Flag Val START 1 16000 0 0 0 20 128 16 0 0 1 16016 0 0 0 20 128 17 0 0 1 16032 0 0 0 20 128 18 0 0 1 16048 0 0 0 20 128 19 0 0 1 16064 0 0 0 20 128 23 0 0 1 16080 0 0 0 20 128 24 0 0 1 16096 0 0 0 20 128 25 0 0 1 16112 0 0 0 20 128 26 0 0 END

Refer to the device specification for the Point Index (Information Number) listing available for control direction.

The module can also send a periodic General Interrogation command in order to initialize and refresh the event-updated points in its database. The slave keeps a list of all data subject to General Interrogation.

Step 7: Transfer the Configuration (page 68) from the Computer to the module.

2.3 [Backplane Configuration]

This section provides the module with a unique name, identifies the method of failure for the communications for the module if the processor is not in RUN mode, and describes how to initialize the module upon startup.

2.3.1 Module Name

0 to 80 characters This parameter assigns a name to the module that can be viewed using the

configuration/debug port. Use this parameter to identify the module and the configuration file.

2.3.2 Read Register Start

0 to 4999 The Read Register Start parameter specifies the start of the Read Data area in

module memory. Data in this area will be transferred from the module to the processor.

Note: Total user database memory space is limited to the first 5000 registers of module memory, addresses 0 through 4999. Therefore, the practical limit for this parameter is 4999 minus the value entered for Read Register Count, so that the Read Data Area does not try to extend above address

4999. Read Data and Write Data Areas must be configured to occupy separate address ranges in module memory and should not be allowed to overlap.

2.3.3 Read Register Count

0 to 5000 The Read Register Count parameter specifies the size of the Read Data area of

module memory and the number of registers to transfer from this area to the processor, up to a maximum of 5000 words.

Note: Total Read Register Count and Write Register Count cannot exceed 5000 total registers. Read Data and Write Data Areas must be configured to occupy separate address ranges in module memory and should not be allowed to overlap.

2.3.4 Write Register Start

0 to 4999 The Write Register Start parameter specifies the start of the Write Data area in

module memory. Data in this area will be transferred in from the processor.

Note: Total user database memory space is limited to the first 5000 registers of module memory, addresses 0 through 4999. Therefore, the practical limit for this parameter is 4999 minus the value entered for Write Register Count, so that the Write Data Area does not try to extend above address

4999. Read Data and Write Data Areas must be configured to occupy separate address ranges in module memory and should not be allowed to overlap.

2.3.5 Write Register Count

0 to 5000 The Write Register Count parameter specifies the size of the Write Data area of

module memory and the number of registers to transfer from the processor to this memory area, up to a maximum value of 5000 words.

2.3.6 Failure Flag Count

0 through 65535 This parameter specifies the number of successive transfer errors that must

occur before halting communication on the application port(s). If the parameter is set to 0, the application port(s) will continue to operate under all conditions. If the value is set larger than 0 (1 to 65535), communications will cease if the specified number of failures occur.

2.3.7 Pass-Through Events

Y or N (N = Default) This parameter specifies if event messages received on the Master ports will be

2.6 [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 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.

2.6.1 Enable Code

0 = Disabled 1 = Enabled, will execute using Poll Interval parameter (page 40) (seconds) 2 = Conditional (executed when point in database changes) This field defines whether the command is to be executed, and under what

conditions. To disable the command, set this parameter to 0 (Disabled). You can still execute commands through the processor, using a Special Function block.

To enable the command, set this parameter to 1.  Set the Poll Interval Time to 0 to execute the command during each scan of

the command list.

 Set the Poll Interval Time to a value in seconds, to execute the command at

the specified interval (page 40).

To execute the command only if the internal data associated with the command changes, set this parameter to 2. This value is valid only for write commands.

2.6.2 Database Index

Database Index is the location in the module's database to use as the source for the data in the command. Refer to Data Type for specific information on addressing (page 41).

ProSoft Technology, Inc. Page 39 of 152 February 22, 2013

Configuring the MVI56-103M Module MVI56-103M ♦ ControlLogix Platform User Manual IEC 60870-5-103 Master Communication Module

2.6.3 Poll Interval

This parameter specifies the minimum frequency at which the module should execute the command when the Enable Code is set to one 1. 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, as quickly as possible.

2.6.4 Session Index

0 to 31 Session Index represents the session index in the module to associate with the

command. This index is set when the session is read in from this file. The range of values for this field is 0 to 31.

2.6.5 Sector Index

0 to 4 Sector Index represents the sector index for the specific session. There are a

maximum of five (5) sectors per session.

2.9 Uploading and Downloading the Configuration File

ProSoft modules are shipped with a pre-loaded configuration file. In order to edit this file, you may transfer the file from the module to your PC or locate and load the file from the distribution CD-ROM supplied with the module. After editing, you must transfer the file back to the module for your changes to take effect.

This section describes these procedures.

Important: The illustrations of configuration/debug menus in this section are intended as a general guide and may not exactly match the configuration/debug menus in your own module. For specific information about the configuration/debug menus in your module, refer to The Configuration/Debug Menu (page 68).

2.9.1 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 or receive 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.

2.9.2 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.

The module uses the Ymodem file transfer protocol to send and receive configuration files from your module. If you use a communication program that is not on the list above, please be sure that it supports Ymodem file transfers.

3 Ladder Logic

Ladder logic is required for application of the MVI56-103M 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.

3.2 Command Control Data Object

In order to support the command control option of the module, a controller tag array, I103Cmds[ ] and two Boolean tags, I103CmdExecute1 and I103CmdExecute2. The bits in the I103CmdExecute tags trigger ladder logic that moves the command parameters contained in the I103Cmds[ ] array out to the module for execution on the networks. The I103Cmds[ ] are created using the User-defined Data Type, I103Cmd, that contains the data necessary to build a user command. The following table describes the structure of this object.

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 requests.

Example ladder logic to use this feature is shown in the following rung:

Page 60 of 152 ProSoft Technology, Inc. February 22, 2013

MVI56-103M ♦ ControlLogix Platform Ladder Logic IEC 60870-5-103 Master Communication Module User Manual

When the trigger bit (I103CmdExecute1) is set, the module will build a block 9901 with the command contained in the first command of the I103Cmds[ ]. The module receives this block and builds and sends the command to the specified control device. The data for the command element in the I103Cmds array is shown in the following illustration.

The following rung displays ladder logic to build a 9902 block to place commands 2 and 3 of the user command list configured in the module's command queue:

When the trigger bit (I103CmdExecute2) 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.

3.3 Event Message Data Object

The module can be configured to pass event messages received from the controlled devices to the processor. 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 table describes the structure of this object.

The example ladder logic defines a 20-element array of the I103Mevent 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.

4.5 Frequently Asked Questions

This section provides answers frequently asked questions about the ProLinx 103M module.

4.5.1 Why is the module not communicating with the slave?

First, ensure that the slave Data Link Address is configured as a slave (session) in the configuration file. The module will only try to initialize slaves identified by Data Link Addresses that are currently configured as sessions. Refer to technical specification for your protection equipment for its Data Link Address. You should also check to see if the common ASDU address is configured as a sector in the module. Make sure all port communication parameters match the slave parameters (baud rate, parity, and so on). Finally, look at the cables and ensure that the correct communication mode is set (RS-232 or RS-495).

4.5.2 The slave is responding but I cannot see the monitor data in the Module database.

Ensure that the monitor points are correctly configured. Refer to your protection

equipment’s documentation for the correct ASDU type, Function Code, and

Information Number. These values must match the parameters that are entered for every monitor point in the [IEC-103 Master Session 0] section of the configuration file.

The addressing type in the module database depends on the point ASDU type. The Database Index parameter can be interpreted as bit, byte, word, or doubleword address. For more details, refer to Data Types and Mapping (page 99).

4.5.3 How can I confirm if the configuration was received by the module?

You can verify this using the Debug menu. Refer to Diagnostics and Troubleshooting in this manual for information on using the Debug menu (page

67).

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:

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.

RS-232: Modem Connection (Hardware Handshaking Required)

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

ProSoft Technology, Inc. Page 93 of 152 February 22, 2013

Reference MVI56-103M ♦ ControlLogix Platform User Manual IEC 60870-5-103 Master Communication Module

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).

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 MVI56-103M ♦ ControlLogix Platform User Manual IEC 60870-5-103 Master Communication Module

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.

5.2 General Concepts

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

5.2.1 Module Power Up

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

o Initialize ControlLogix 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.

5.2.2 Main Logic Loop

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

Reference MVI56-103M ♦ ControlLogix Platform User Manual IEC 60870-5-103 Master Communication Module

5.2.3 Backplane Data Transfer

The MVI56-103M module communicates directly over the ControlLogix backplane. Data travels between the module and the ControlLogix 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 ControlLogix processor. The input image for the module is set to 500 bytes. This large data area permits fast throughput of data between the module and the 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 ControlLogix processor can send special control blocks to the module to instruct it to perform a special task. The output image for the module is set to 496 bytes. 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 ControlLogix processor, the MVI56-103M 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 ControlLogix 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.
