  1. Laptop instead of panel

    Hi guys,  I come with positive feedback. I succeeded to communicate with PLC using CX Designer in test mode with PLC..Everything runs ok. The issue I found in position of DIP switch  for COM port. I set the switch in OFF and then combination was ok.. When switch is in ON position is activated the  RS232 board will not follow seria communication l settings. Thank you for your advises.
  2. Laptop instead of panel

    Hi Crossbow, I was expecting that navigation all 5 button for navigation between pages to remain displayed. Also I expect that table to remain displayed and instead values to see in the table strange signs, like #### or like ****.  But table disappears, not only values.  Navigation buttons also disappear.  That is a strange behaviour.  When I run in simulation mode without connection to PLC, everything appears correctly.  About cable, I think that photovoltaic has right.  As long I have the computer ( laptop ) connected to PLC and I run the HMI visualisation on laptop it should use that cable.  For example: at PC side, pin no. 5 is ground.  In your cable you said that I should make a bridge between 5 and 4.  pin no. 9 is not in use at PC side but in your example is connected with no. 9 at PLC, that is ground at PLC serial connector.  That cable that you proposed will be ok when I will use connection between PLC and a real PT. Not for PC.  Please, can you advise me what settings I should use for communication between PC and PLC when I run is simulation of visualisation? Maybe there is the key of problem. 
  3. Laptop instead of panel

    Hi photovoltaic, I am sorry for delayed feedback. I traveled a lot in last 2 weeks. Now I come back with details. I rebuild my cable as you showed above. I am able now to communicate with PLC using CX-Programmer by serial port. But, unfortunately I am not able to communicate from visualization project. I used as parameters 19200 7,E,2. in both sides PLC and visualization project . Of course the COM port of laptop has same settings, but still unsuccessful. I tested also different other options. 1. Are you sure that this cable is applying also for communication between PT an PLC? Also I observed that something strange is happening with my visu project when I try to use in connection with PLC. The whole content of page is not displayed. I mean lamps, table where I intend to display or modify values, or buttons for page navigation are not displayed. And after 5 seconds an error message inform me that is no communication. But when I use simulation mode, everything works perfect. It looks like my project has a bug. and I intend to create a new one from scratch, 2. Do you have a suggestion of what hardware I should choose for my new project?   Many thanks in advance

    Many thanks for your suggestion. I build by myself the serial cable following a diagram found on internet.  Maybe is not the correct one. Also I will really appreciate if you can send me the right schematic of serial cable.
  5. Laptop instead of panel

    I try, few weeks ago, to connect the PC to PLC via serial, and I didn't succeed. It is necessary to make some settings also in the PLC after inserting the module CP1W-CIF01  ? I set the necessary switch to activate the port. Should I set something more in the project? I found that setting as CPU option to be networked. Is that the setting that I need to choose for communication trough serial port?
  6. Laptop instead of panel

    Hi photovoltaic, thank you for quick reply. As you may see on above screen shot I tried to use the serial communication. Basically I added to PLC  serial communication module CP1W-CIF01 . Also I set the corresponding switch. Unfortunately, I did not succeed to connect my visualization to PLC. In my visualization project  I choose bellow settings for communication. Also I experimented the other options, but no success. Is necessary to make some additional settings in PLC also ?  What is your suggestion for values as good settings for serial communication setup? Thank you in advance, dekor.
  7. Laptop instead of panel

    Hello to everyone, I want to work for a project that I intend to use as tool in my laptop. The goal is use a visualization runtime in my laptop connected to a CP1L Omron PLC. Available port is USB or I can add RS232 module.l  The PLC is already programed and runs ok. That runtime will be used for short period of time, during equipment startup. My idea is to use USB port of PLC to communicate with laptop and visualization will allows me to observe or modify some binary values (Inputs, Outputs or memory bits). Also, I would like to display and change some values of few timers or counters using DM area where are located. At this time, values of timers and counters might be changed using the module display CP1W-DAM01 attached to PLC. But position of PLC is very uncomfortable to access display and make changes. My intention is to create a panel project in my laptop and to use function: Tools / Test / Connect to PLC My question is: would be possible using USB cable? What type of panel should I configure in CX designer to use? Or, if I will add a serial RS23 module and I will activate by switch will be ok? Thank you and wait for your advices
  8. WinCC - older version or not fully installed?

    Hi, WinCC SP5 I think that must be installed on Win10, not on Win7.
  9. S5 GREEN RUN. NO RED, BUT NO GO

    Connect to CPU. and read ISTACK  Tell uș what you found. 
  10. Siemens hmi

    Hi, Some of the backup can be decompiled and you will know which of PLC variable is connected to HMI object. And not only that info. Users, password and other things might be reviled  Knowing that you may build a new project for your HMI. Is that OK for you? But you did not wrote anything about your HMI. Is your panel a text display or is touchscreen type? Send me more details and a backup of your HMI.
  11. Siemens LOGO PID

    Hi, LOGO has no PID function. Only PI.
  12. S7-200 PLC

    Hello, You may need to select the new type of CPU on the project, then compile and download if no errors occurs in compilation phase. Normally should not be errors on compilation, but... Or you may go online with new CPU and when you try to download, a warning should appear and will ask you to change CPU type.
  13. S7-200 PPI cable

    Hi again,  No need to work that much.  You can buy even much cheaper than you build yourself. One more think: No USB to RS485, because you need to select Com port as communication path on Microwin. Selection USB is for genuine Siemens adapter,.
  14. S7-200 PPI cable

    Hi, Dont follow this drawing.  You have to create an RS232-RS485 converter. I did also RS232-RS485 converter and it works for S7-200. 
  15. HOW CAN I USE NETWORK I/O ON LADDER SOFTCOMFORT?

    You use ModBus communication, therefore on outputs the values are automatically allocated to registers.You can read the values from registers. Check on LOGO allocation table the register you need. Be aware that outputs must be shifted with -1 There is no output 0 on LOGO,  but 1
