Battery Life Advisory

The MVI46, MVI56, MVI69, and MVI71 modules use a rechargeable Lithium Vanadium Pentoxide battery to backup the real-time clock and CMOS. The battery should last for the life of the module. The m odule 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 approxim at ely 21 days. When the battery is f ully dischar g ed, t h e modul e will revert to the default BIO S and clock s ett ings.

Note: The battery is not user replaceable.

1.5 Install 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 MVI56-104S module. Refer to your Rockwell Automation product documentation for installa tion 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 MVI56-104S 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 OF F. 2 Align the module with the top and bottom guides, and slide it into the rack

until the module is firmly against the backplane connector.

3 With a firm but steady push, snap the module into place.

2.3 [SNTP CLIENT]

The [SNTP CLIENT] section of the CFG file is used to speci fy th e par ameters for the Simple Network Time Protocol (SNTP) client provided with the protocol driver. This client is required in order to keep the driver's internal clock set correctly. This version of the driver supports SNTP Revision 3 and stratum bet ween 1 and 14.

SNTP is used for time synchronization of produced and consumed commands. When an exchan ge occurs the driver compa res time s tamps from the previo us exchange. When the new exchange time is less than the previous exchange, the exchange is ignored. This can occur when the Ethernet packets are routed and delayed . Tim e sy nc hr oni zation provides for dat a i n tegr i ty .

The SNTP driver will compute a new clock value every 5 minutes using the average val ue of 10 samples each collec t ed over an ap pr oxi m a t e 6- second period. This new value will be used to adjust the clock maintained by the SNTP driver and used by the application. If a valid database register is specified, the driver will place the time value into the module's database. The first two registers will contain the number of seconds and the next two registers will contain the number of microseconds since January 1, 1970.

A list of some of the common NTP servers can be obtained at http://www.ntp.org/, http://www.eecis.udel.edu/~mills/ ntp/servers.html, along with the appropriate IP address. Other server lists can be found by searching the World Wide Web for "NTP Servers".

Enter in dotte d notation This parameter sets the IP add ress of the NTP server to utilize for time

acquisition. Select an NTP server with the greatest accuracy that can be accessed all the time from your network. Setting this IP address to 0.0.0.0 disables SNTP server requests.

2.3.2 Time Zone

-11 to 11 This parameter specifies the time zone offset to be used from the UTC time

zone. A value of zero uses UTC time. If the value entered is positive, the time zone is west of the UTC time zone (that is, Eastern Standard Time is 5). If the value entere d is negative, the time zone is east of the UTC time zone (that is, Continenta l Europe is -1).

2.3.3 Use Daylight Savings Time

Yes or No This parameter specif ies if dayligh t saving s time will be used in the time

computation.

2.3.4 Database Register

-1 or 0 to 3992 as an eve n val u e This parameter specifies if the NTP time computed by the driver is to be placed

into the module’s database. If a value of -1 is specified, the time will not be placed into the database. If the value is between 0 and 3992, the time will be placed in the database. The first 4 bytes will represent the seconds since 1/1/1970, and the second 4 byte s will represent the number of microseconds. An even value should be used for the register value in order for the data to be stored correctly.

2.6.5 Parameter Offset

This parameter specifies the IOA (Information Object Address) offset to the parameter data for the normalized parameter data. The value entered is added to the Information Object address for th e ass ociated point to compute th e parameter IOA address.

The Master may send a "Parameter of Measured Normalized" or "Parameter of Measured Scaled" command using the parameter IOA in order to change the deadband values for specific points.

Note: The Low Limit and High Limit values are always calculated based on the deadband value as described in the following table.

Point Value

Threshold Determined by the deadband set in the configuration file or altered by the write

command. Low Last reported ev ent value - threshold. High Last reported event value + thr eshold.

For example, if the MVI56-104S configuration sets two M_ME_NA points with IOA (Point #) o f 600 and 601 and a M_ME_NA Par am eter O f fset v alue of 3000, it would result in the parameter points shown in the table.

2.20 Group Codes

One aspect of the point configuration database that leads to confusion is the group definition field. This assignment for each point assigns a point to one or more interroga tion groups. Use of interrogat ion gro ups permits the controlling unit to interface with a specific set of data. Refer to the IEC 60870-5-104 standar d for a full di sc uss ion of interrogation groups. A specific gr o up, Per i odi c data grou p, reports data points on a set fr equency. The frequ en cy is set in the Cyclic Da ta Transmission parameter in the configuration file. Remember that a point can be assi gned to more th an on e gr ou p.

If the highest bit (bit 31) is set, data will be produced by the driver for the specifi ed point at the rate set for periodi c dat a ge n er ati o n. Bi t 30 (0x4 00 00 00 0) enables scanning of this poin t for event generation. If the bit is clear and the data type is set for scanning, events will be generated for the point. If the bit is set, events will not be generated for the point. This feature can be used to select which points will generate events for the cont rolling station and can get rid of event data that is not important to the application.



Ladder logic is required for application of the MVI56-104S module. Tasks that must be handled by the ladder logic are module data transfer, special block handlin g, an d st at us dat a receipt. Additional l y, a p ow er - up han dl er may be needed to handle the initialization of the module’s data and to clear any process or faul t conditi ons.

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 la dder will work without modification.

All data related to the MVI56-104S is stored in a user-defined data type. At least one instanc e of each data ty pe is required before the module can be used. This is done by declaring a controller tag variable or variable arra y of the data type in the Controller Tags Edit Tags dia log bo x (th is will be done automatically if you use the Add-On Instruction Rung Import file or use a copy of the provided ladder logic sample).

3.1 User-defined Data Types

3.1.1 Module Data Object (ModuleDef870)

To hold and org ani z e all data relat ed to th e M VI56-104S module, data is stor ed in Controller Tags and Tag Arrays based on standard data types as well as special User-defined Data Type s (UDTs).

The ModuleDef870 data object is the top-level UDT that organizes all data related to the module into one overall data structure.

User Data Objects

These objects are simple controller tag arrays, composed of 600, 16-bit signed integer (INT) data words (each array element is one 16-bit word). These arrays hold data to be transferred between the processor and the MVI56-104S module. Data is transferred between the processor and the module as "pages" of up to 200 words (array elements) of user data per transfer.

Name Data Type Description

ReadData INT[600] Data read from module Write D a ta INT[6 00] Data to write to modu le

The ReadData array size should be set to match the value entered in the Read Register Count parameter o f the IEC8704S.CFG file. For ease of use, this array should be dimensioned as an even increment of 200 words. This data is paged, 200 words at a time, from the module to the processor. The ReadData task places the data received into the proper position in the ReadData array. Use this incoming data for status and control in the ladder logic of the processor.

The WriteData array size should be set to match the value entered in the Write Register Count parameter o f the IEC8704S.CFG file. For ease of use, this array should be dimensioned as even increments of 200 words. This data is paged, 200 words at a time, from the processor to the module. The WriteData task places the values in the WriteData array into the output image for transfer to the module. This data is passed from the processor to the module for use as status and control information by other nodes on the network.

Block Transfer Statistics Data Object (BlkStat870)

This low-level data type creates tags to hold module status values that show input and output image (I/O) block transfer activity. These block transfers occur between the module and the ControlLogix processor. This low-level structure is used to create the higher-level structure, InStat870.

Name Data Type Description

Read INT Total number of i nput image blocks transferred Write INT Tot al number of output image blocks transferred Parse INT Total number of blocks parsed (good blocks received and

processed)

Err IN T Total num ber of block transfer errors (bad blocks or no

blocks received)

These tags hold values of module internal counters that keep a running total of how many input and output image blocks have been transferred between the module and the ControlLogix processor. During normal operation, the values display ed for Read, Write, and Parse should increment together and be very close to the sam e v alues, unless backplane errors are occur r i ng. If bac kpl a n e errors are occurring, the Err va lue will increment and the Parse value will not.

As long as Read, Write, and Parse continue to increment and Err does not change, this indicates normal backplane activity. An occasional backplane error may occur, even in normally functioning systems. So, if the value in the Err counter slowly increases over time, this is generally not a cause for concern. However, if normal backplane transfers appear sluggish or non-functional, if input data is being lost or output data is not being sent, especially when the Err counter is incrementing frequently, th is could indicate a hardware failure, I/O configuration problem, or, for remote rack installations only, a process network problem that may need to be corrected.

3.1.3 Control Data Object (Control870)

The Control870 data structure is used to build the top-level data structure, ModuleDef870. Control870 co ntains data and stru c tur e fr om four ( 4) lower - l evel data objec ts, EventType870 (for events time-stamped with GMT date/time), EventTypeUTC8970 (for events time-stamped with UTC date/time), ReadTimeType870 (reads time from module into controller tags), and SetTimeType870 (sets module time to match time received from controller tags).

The data points contained in those data objects will be discussed in their respective sections.

Name Data Type Description

3.3.1 Output Data Initialization (1000 to 1019) Blo cks

The module can be configured to initialize its internal IEC Input databases, the Monitor Data that will be sent to the re mote IEC Client, to the values stored in the Control Lo gi x pr oc es s or IEC870.WriteData controller tag array at the time the module is started or rebooted before it begins to respond to da ta requests from the remote Client. This feature requires ladder logic support. If the configura tion parameter "Initialize Output Data" in the IEC8704S.CFG configuration file is set to "1" (1 equals "Yes"),then, whenever the module performs a restart or reboot operation, it will send a set of one or more special block ID requests to the processor. These blocks must be handled by the ladder logic and return the requested monitor data. Here is the format of an Initialize Output Data Read Block.

Offset Description Length

0 Reserved 1 1 1000 to 1020 1 2 to 248 Spare 247 249 1000 to 1020 1

The module will request only the a mount of data set in the user configuration parameter Write Register Count in the IEC8704S.CFG configuration file. Special logic must respond to each special input block request by sending a corresponding response output block in the followin g for mat.

Offset Description Length

The IEC monitor data received in the special write block will be put into the proper place in the module’s IEC databases according to the setting in the configuration file.

Note: If the "Initialize Output Data" parameter is set to "1" ("Yes") and the special ladder logic required to process Block IDs 1000 through 1019 does not exist in your current program, the module will fail to complete its initialization process and will not begin data transfer operations. The standard ladder logic sample includes an example rung that shows how to process these special Block ID codes.

3.3.2 Event Messages (9958) Blocks

Bloc k ID 9958 is reserved to se nd Event Messages from the processor to the module. Each block can send up to 10 events to the module in each block transfer.. If a value of 9958 is placed in the Write Block ID of the output image, event messages are sent from the processor to the module. For more information about IEC events, refer to Events (page 131).

The module supports a buffer queue of 99 events per data type. When the queue is full for a particula r data type is full, the module will delete the oldest event in the qu eue if a ne w event is received.

This block should be used only to pass events with a predefined time-stamp (the module will automatically send time-stamped events when monitor database values chan ge) . While usi n g bl ock 9958, disable the eve nts for th os e specific points (refer to G r oup Codes (page 49)) to avoid multipl e event generation (caused by point value update through bo th the database and Block ID 9958 ).

The origin al fir m war e s u pp or ted only Greenwich Mean Time (GMT) format timestamps. Beginning with firmware version 1.20 and later, a Coordinated Universal Time (UTC) time-stamp option was made available. Now there are two versions of Block ID 9958, one for GMT time- stamps and one for UTC time-stamps. Be sure to use the correct one for your application.

If you follow the examples in the sample ladder logic, it is easy to select which 9958 block structure to use. Use the controller tag structures, IEC870S.Control.EventBlock_GMT, for GMT time-stamped events. Use the controller tag structures, IEC870S.Control.EventBlock_UTC for UTC timestamped events.

The followin g topics show the differe nce s in block formats between thes e two types of 9958 blocks and define the controller tag structures associated with them.

5.2 IEC-60870-5-104 (104S) Protocol Implementation

The intent of this section is to provide a quick understanding of how the 104S module implements the IEC-60870-5-104 protocol, without going into complex details of the specification.

The IEC-60870-5-104 protocol applies to Telecontrol equipment and systems with data transmission for monitoring and controlling geographically widespread processes. This protocol consists essentially of the IEC-60870-5-101 protocol, with the addition of TCP/IP as the transport mechanism.

Any application with the IEC-60870-5-104 protocol consists of a client (Controlling Station) and one or more servers (Controlled Stations). The client constantly monitors and controls the data from each server in the TCP/IP network.

The MVI56-104S works as an IEC-60870-5-104 server; it can send monitor data, receive commands, or generate events to the client unit.

5.2.1 Module Address

The MVI56-104S module is identified at transport level (using the IP Address) and at application level (using the Common ASDU Address).

IP Address

The MVI56-104S module is identified by a unique IP address on the TCP/IP net work. You must edit the WATTCP.CFG configuration file (o r use the configuration tool) to enter a valid IP address. The following example lists the default contents of the WATTCP.CFG file:

In this example, the MVI56-104S module is identified by IP address

192.168.0.250 in the IEC-60870-5-104 network, with a netmask (subnet mask) of

255.255 .2 55.0 and a default gatew ay address of 192.168.0.1. Because there could be several devices in the same TCP/IP network, some

applications may require a co nnection control (from which IP addresses the module may receive valid messages).
