PR 1792 Operating Manual Introduction

Minebea Intec EN-5

1 Introduction

OPC Server PR 1792 is part of a system for transmission of current data between Minebea Intec

instruments and PC programs which can operate as an OPC client. The system comprises the connected

weighing- / batching Instruments, a PC with programs and the connection of all components. The

platform for the system is the PC under operating system Windows NT, Windows 2000, Windows XP or

Windows 7. For some system components, separate manuals are available to which only reference is

made in this documentation.

The OPC server permits access to the data of instruments connected to the PC by OPC client

application. Depending on the instrument the connection can be done via serial interface and/or via

Ethernet. With instruments provided with serial connection to the PC, protocol EWCOM V3 is used.

Due to differences related to application, communication and memory repartition,

transmitters/indicators and batching systems are discussed separately in this manual, wherever

necessary.

1.1 Brands, trade names

Windows NT, Windows 2000, Windows XP, Windows 7 are registered trade names of Microsoft

Corporation. All other brands or product names are brands or registered trade names of the relevant

manufacturer or holder.

1.2 Exemption from liability

The PR 1792 program is a state-of-the-art development. No warranty is taken for correctness, in

particular, in connection with third-party software and hardware components required for program

operation. Liability for damage due to other system components or faulty handling of this program is

precluded by the manufacturer. The use of the program implies recognition of the above-mentioned

stipulations.

Protocol driver

PR 1792 EWDRV_01 Communication with

the instrument

An instrument is addressed by the EW protocol driver EWDRV_01 via a serial PC interface or via

Ethernet. Data communication (polling) is automatic by PR 1792. Plausibility checking of software

configuration and actually connected instrument is provided, whereby localization of errors (such as

confusion of connectors at the PC interface) is possible.

OPC server PR 1792 moves the data in blocks of 64 bytes. Data throughput is increased, if you group

the data in blocks of 64 bytes, e.g. 64 – 127, so that all inquiries with md, mx, mr, ... are transmitted in

a block.

3 Configuration of the OPC server

3.1 Survey

In conjunction with the installation, the OPC server must be configured.

When starting program 'PR 1792 OPC Server', the EWDRV_01.EXE communication process is started,

unless this was already done. The communication process starts only once. If it is already running, the

start is canceled. The communication process is minimized into an icon in the task bar and started.

PR 1792 starts always with a window in the size used last. Both programs can be terminated as usual

under Windows.

File

[File]–[Exit] terminates the server program.

View

[Toolbar] and [Status Bar] can be activated separately.

eventually an option card has to be plugged-in (see list in chapter 3.2.2.). Select protocol EWCOM V3

(ASYCOM slave). Configure identical interface parameters (e.g. Ewcom V3, 9600 Baud, 7 bits, even

parity, ... ), as described in the relevant instrument documentation.

3.2.4 Ethernet

Some instruments (see list in chapter 3.2.2) can be connected via Ethernet TCP/IP.

Enter the network address in the mask at [COM port / IP Address] (e.g. \\130.143.1.5, see Manual for

the respective instrument / Ethernet-card). The address is defined by the local network administrator

or if DHCP is used, automatically given from the Server. Take care, that double definition of IP

addresses does not happen!

3.3 Statistics

For diagnosis purposes, the actual data volume per second can be displayed.

Click on or select [Configure]-[Show/Edit Group Status] for access to the configuration menu.

Select a 'Group' and click on [Statistics].

As long as this window remains open, all data are updated continuously.

There are four different groups of commands:

'Std. Poll Messages'

'Block Poll Messages'

'Spont Msgs. Received'

and

'Poke Messages sent'

The average number of commands per second is given with each value. The total of all four values is

the overall number of commands per seconds.

'Std. Poll Messages'

: number of commands and replies of type 'mbxxxlxx' (reads a string)

'Block Poll Messages'

: number of block transmission orders.

'Spont Msgs. Received'

: number of spontaneous messages. E.g. value ST_WGT_A is sent at every

weight change.

'Poke Messages sent'

: number of write commands.

'Active Point'

: number of active 'Items' which were connected by the OPC client.

'Active Blocks'

: number of active blocks. For efficiency reasons, the 'mx', 'mr' and 'md' commands are

not transmitted individually. Data blocks of 64 bytes (512 bits) are transmitted instead.

64-byte data blocks

All data belonging to one of the data blocks are

transmitted in a telegram. Detection and

management of the data affiliation to a block are

by the OPC server.

Bit 1024 ... bit 1535

Bit 1536 … bit 2047

Bit 2048 ...

…

For this reason, compactness of memory locations is purposeful. If data are distributed over the

complete SPM memory, a large number of data blocks with few useful contents must be transmitted.

Therefore, the number of active blocks must be as low as possible.

'Max update time [ms]'

: This is the maximum time required by an 'Item' for data updating. This time

increases with the number of 'Items' and 'Groups', because the data communication increases, i.e. the

time remaining for each individual 'Item' decreases.

Priority over other data transmissions is given to write commands. Very intensive data writing by the

client program can impair the data read rate.

3.4 'Logging' menu – options for trouble shooting

3.4.1 Survey

During OPC server operation, various error messages are possible. These are displayed in the OPC server

main window:

Every day, the OPC server creates a log file with the date of creation in the file name in format:

LOGyearMonthDay.log. e.g.. "LOG20070815.log".

The current log file can be opened via menu [Logging]-[View log in Editor] in an editor.

3.4.2 Logging settings

Adjust the editor to open the log file for logging. The default setting is "Notepad.exe".

Moreover, the time during which log files have to be kept can be adjusted. With "Keep for this many

days:" set to '0', all log files are kept for an unlimited period of time.

The OPC server uses the file name and not the date as criterion for deleting.

3.4.3 Debug enable

This option activates the debug mode: in addition to the other stored

error messages, further information on internal sequences is

generated in the OPC server. This mode is intended for diagnosis

purposes. During normal operation, it should not be activated,

because a large quantity of data consumes a lot of memory space on

the hard disk and computer capacity.

3.4.4 Message Debug

For extended diagnosis purposes. messages which extend partly to

communication level are generated. The data quantity is extremely

high, which is a considerable load for the overall computer.

WARNING

: Please, use this mode only for diagnosis purposes!

4 Operation with an OPC client application

4.1 General

The PR 1792 OPC server is delivered with a program example of an OPC client:

OPC_Client.exe

The description of an OPC client is based on the following program. This application example can be

used for testing the OPC server functions and finding errors. In case of problems with a client program

written by yourself, e.g. a Visual Basic Program, check first, if the relevant functions can be tested with

the OPC client.

4.2 Starting OPC client

Start program OPC_Client.exe.

4.3 Connecting client and server

Now, connect the client to the server.

[OPC]-[Connect]

Operation with an OPC client application PR 1792 Operating Manual

Unless an error message is displayed after pressing "OK", the client is connected with the server.

4.4 Adding items

Now, data from all instruments connected to the OPC server can be read and written.

In this example, two instruments are made known to the OPC server: "PR 1713" and "Batcher".

[OPC]-[Add Item]

You should always activate 'Use

native type'.

A complete 'Item' name is a combination of the 'group' name, followed by a dot '.' and the 'Item'

name, e.g. PR 1713.ST_WGT_A.

Click on an instrument ('group') first and then on one of the logic 'Items'. Store this ‘Item’ in the list

by clicking on [Add Item].

Click on [Done] to complete adding of new 'Items'.

PR 1792 Operating Manual Operation with an OPC client application

Minebea Intec EN-19

Now, the weight value from an instrument is read and continuously updated. The time stamp shows

date and time of the read value.

The OPC server status changes from 'IDLE' into

'OK: DEVICE ALIVE' and the traffic light changes

to green.

Click on the 'Info' button or select

[Configure]-[Show/Edit Group Status]

In this example, data communication was built

up with OPC group 'PR 1713' and not with OPC
