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.

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?

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.

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

Hi, WinCC SP5 I think that must be installed on Win10, not on Win7.

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

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.

Hi, LOGO has no PID function. Only PI.

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.

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,.

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. 

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

Hi, You must allow LOGO to be accessible    Go to online settings \ Access control settings  and allow data to be accessed by Ethernet. I am not sure also about your program, but might be also necessary to add on parallel with your output Q1, an network output NQ1( V0.0 for example). Then you will check in HMI the status of  network output,  respectively status of V0.0 Try those things and let us know your results. 

Hi, did you switch off and try to start BM without memory cartridge ? Then was no program in BM? Try to copy and remove memory without power off. Was a password request when you copied the program?

What I understood is that you did not copy the program from memory cartridge into LOGO BM (base module). 1. You need to copy program into BM 2. Connect your laptop and upload the program from BM into your laptop.Save-it into you laptop. 3. Modify the program as you need and download-it int o BM.   Attacheed you will find instructions about working with memory cartridge. Send me feedback about your progress.LOGO 6 working with memory card.pdf   It looks like I cannot attach the file. Please check next document from original link You will find necessary info on pages 203-215. https://cache.industry.siemens.com/dl/files/461/16527461/att_82564/v1/Logo_e.pdf
