    IMHO: The use of Modbus ASCII is not implemented very often as opposed to Modbus RTU which uses the binary format.  Also the Enron extensions to Modbus do not support the ASCII implementation.  Are you sure that you are trying to implement Modbus ASCII or Modbus RTU?  The answers to this post will lead me in the direction to help you do the LRC or CRC in ladder necessary.

    OK,  first thing you do is register at MR.PLC.com.  There are plenty of registered users who post here and you need to become one of them. Second, what model Omron PLC? Third, what development tool do you plan to use? Fourth, what documentation do you have already?

    I have supported others who have used CX Supervisor with SQL Server and know that they have been successful.  One thing that CX Supervisor will not support is SQL Server syntax errors.  If you use the wrong syntax for SQL, CX Supervisor will not check for bad syntax and will report the command as good.

    There is the brute force method.  Use snooper software like the Comm Lite 32 found in this site's download section and trap the command that sends the password.  Most Japanese PLCs use one 4 digit hex register as the password.  Set up a  VB application to try all possibilities from 0000 to FFFF.

    Ok, Scaver.  We finally got it loaded to the Omron OI download section of this website.  Here is a full working demo of the CX Supervisor SCADA software.  It allows 20 tags and works for one hour at a a time. http://www.mrplc.com/cgi-bin/code/filedisplay.cgi?category=oiomron

    La función de escritura de ExportLog usa las convenciones siguientes para archivos separados de coma automáticamente engendrando de valores para la exportación: Todo filenames engendrado de CSV contendrá por lo menos el "Los datos Ponen el nombre" + "timestamp" Y un. la extensión de CSV. CSV es un formato que es reconocido directamente por paquetes de spreadsheet tal como Sobresale y puede por lo tanto sea abierto y es considerado con esta aplicación. e.g. MyData Set1999011214.csv Todo estas órdenes exportarán todos los datos en el archivo especificado, para el conjunto denominado de datos al archivo denominado de la salida, en el formato especificado. Los Ejemplos típicos: ExportLog ("Balloon", "*")     o ExportLog ("Balloon", "Altitude,Fuel,Burning,Lift,Group 1" "CSV-BDTM",0, la "output")     o ItemList[0] = "Altitude" ItemList[1] = "Fuel" ItemList[2] = "Burning" ItemList[3] = "List" ItemList[4] = "Group 1" ExportAndViewLog("Balloon", ItemList, "CSV-BDTM", 0, "output") Vea la Referencia de Escritura de Supervisor de CX que se incluye con cada guía de la instalación de Supervisor de CX. ;) ------------------------------------------------------------------------------------------ ----- The ExportLog script function uses the following conventions for automatically generating comma-separated values files for export: All generated CSV filenames will contain at least the "Data Set name" + "timestamp" and a .CSV extension. CSV is a format that is recognised directly by spreadsheet packages such as Excel and can therefore be opened and viewed with this application. e.g. MyData Set1999011214.csv All these commands will export all the data in the specified file, for the named data set to the named output file, in the format specified.

    CX Supervisor no tienen su propia base de datos. Usted debe usar un programa como el siguiente. El siguiente es un extracto del Capítulo 11 en Bases de datos en el Supervisor de CX. ¿Tiene usted los manuales? Las facilidades de la Base de datos del supervisor de CX proporcionan el acceso rápido y transparente a muchas fuentes diferentes de datos, vía una tecnología de base de datos llamó la ACTIVIDAD. El diseño de la base de datos no se cubre aquí, cuando es un sujeto grande explicado completamente en cualquiera de los muchos libros disponibles. Se asume que reveladores que usan estas facilidades de la base de datos tienen un conocimiento de trabajo de bases de datos. Las Funciones comprensivas de Escritura de Base de datos permiten el acceso completo de la base de datos. Las fuentes de datos que se pueden accesar depende de los Proveedores de Datos instalado, pero puede incluir: ? la Sra Acceso ? la Sra Sobresale ? Visual FoxPro ? dBase ? ODBC para el Oráculo ? la Paradoja ? de SQL Camarero ? los archivos de Texto (en TXT y formato de CSV) :D   CX Supervisor does not have its own database.  You must use a program like the following.  The following is an excerpt from Chapter 11 on Databases in CX Supervisor.  Do you have the manuals? CX-Supervisor Database facilities provide fast, transparent access to many different data sources, via a database technology called ADO. Database design is not covered here, as it is a large subject explained fully in any of the many books available. It is assumed that developers using these database facilities have a working knowledge of databases. Comprehensive Database Script Functions allow complete database access. The data sources which can be accessed depends on the Data Providers installed, but may include: ? MS-Access ? MS-Excel ? Visual FoxPro ? dBase ? ODBC for Oracle ? Paradox ? SQL Server ?

    I checked all the forums and databases on CX Supervisor and couldn't find anything about your problem.  I loaded version 4 on a WinMe computer and I could add a dataset.  You have an early version(4).  Try this patch and see if it helps.  Also, if you still have your original install disc,  try installing on another machine in English.  There were some problems with other languages. :-3 I checked out both your links (Thanks chako, for the translator).  You have an impressive site.  I added several links in my Favorites. :) CX_S_4_to_5.zip

    David, When I look at your web site, I see SCS Demo.  Are you trying to use Data Logging in SCS or CX Supervisor?  The instructions are different.  Please tell me the version of CX Supervisor that you are using.  Can you do a screen capture of the problem you are having? Your web site is very interesting and has a lot of good information.  Because I read only English,  I translated some of your Web Site.  Does your site try to bring engineers together to discuss control problems?  Please let us know more about what you do. :D

    Here's a step by step: Procedure: Step 1          To configure the data log, go to “Utilities”, “Workspace” or click on the “Workspace” icon. Step 2          Click the “Logging” tab at the bottom of the active window.   Step 3          Right-click in window and select “Add Data Set”. Step 4          Enter the “Data Set Name” as “Lab_Dataset” (this will be used as the base for the file name generated).                     The “Period” is how often one data log file is closed and another is created.                  The “1 Hour(s)” default is sufficient.                   Click “OK”. Step 5          Right-click on the Lab_Data set created in Step 4 and select “Add Item”.   Step 6           Select an item name that you wish to show in the data log viewer (ie. Pressure).                    “Browse” for the “Expression”, and select “Slider 1” from “Lab 5 Group”.                     Use the default “5 second(s)” “Sample Rate” “On Interval”.  Leave the scale as the default.   Step 7           Similarly, add the following items in the “Lab_Dataset”.  Close “Workspace”. Item Name          Expression Flow                  Slider 2 Volume               Slider 3 Temperature        Slider 4 Step 8           Run the application.  At Runtime, right-click on the page and select “Data Log Viewer”. Step 9           Select “File “, “Open”. Step 10          Browse for the data logging file:  Lab_Dataset.dlv.  Click “Open”.                    Note: CX-Supervisor will create a sub-directory named “Data Logging” in the CX-Supervisor “Project” directory. Step 11          Select all of the data log points to view.                      Click “OK”. Step 12          Click on the “Live Updates” icon.  Go to the “Charts and Graphs” page, move the slider and check the “Data Log Viewer”. :p

    Welcome to Mr.PLC.com!  :) I'm glad you asked, because this is an excellent time to start a discussion on Scada with CX-Supervisor.  CX Supervisor is a wizard based HMI and Data Acquisition package manufactured by Omron.  It is not limited to Omron PLCs and supports other products through OPC. Data Logging is easy to setup when you are doing a time based process.  The wizards will lead you right through the setup.  When you want to data log based on event such as your process, CX Supervisor has a script language to enhance its' built in features. First of all, setup your dataset in Project Workspace|Data Logging Tab.  Add a new Dataset ("ProcessLog").  Add your items to be monitored as Pointnames.  Be sure to uncheck the box that says "Start Data Logging on Application Startup". Second, Open the Animation Editor and set it to Project Level Actions.  Add a Script with the following setup: Script Name:  Start_Data_Logging Trigger Event:  On Condition Expression (pointname):  Process_running StartLogging("ProcessLog") Third, add a new script at the Project Level with the following setup: Script Name:  Stop_Data_Logging Trigger Event:  On Condition Expression (pointname):  !Process_running (Please notice the '!" at the beginning of the Pointname - Inverted) StopLogging("ProcessLog") CloseLogFile("ProcessLog") Run the project and manipulate the pointname "ProcessRunning" from OFF to ON.  The log should start.  When the process is finished, manipulate the pointname from ON to OFF.  The log should stop and the file close.  The next time the pointname is On , a new log with a different time stamp should be created. :) Here's some pages from the Script Reference Manual.

    This is perfectly legitimate no matter how you add a second Ethernet NIC to your computer.  I would leave your company connection as a server assigned IP and assign a static IP in the range of 192.168.0.xxx. BTW, 192.168.0.xxx is an international test network assigned for exactly what you are doing.  No router in the world will pass packets from this network out to the internet.

    Awesome program!! :0 I just download comlite32 and was knocked out!  How long have I looked for a snooper program that would monitor both sides of a serial conversation without having to actually tap the cable!!!  This is going in my Top 10 Utilities directory.  Thanks Ken! :)  I will add it to the Miscellaneous download section on this site!
