ZEN SW takes care of that.- Node address is only needed for V1 CPUs (I am using V2)- Avoid using pro.-based USB-serial converter, very cheap but useless (very expensive at the end of the day).So, problem solved.

The last one worked immediately, at first attempt.Summarizing:- You do not need to know serial port settings. Three of them were based on the same chipset with different form factors and brand names. I have tried with 4 different converters. Lancie1, yes finally I did it.In short, the problem was the USB-serial converter. These two Node Addresses must be the same!' Communications cannot be performed if the node addresses (not COMM ports) do not match!'

See the picture below for how to set the ZEN Programmable Relay CPU Node Address. The attached picture is from the Operation Manual, page 100.(3) See the ZEN Help files topic 'Connecting the ZEN and Communications' for how to set the COMM Port number (1 or 2) and the Zen Software Node Address (0 to 9). This is NOT the COMM port number (which is either 1 or 2). See the The important thing you DO have to set is the Node address (0 to 9).

If your computer does not have a real serial port (very few newer computers do have a serial port), then you need the ZEN converter CS1W-CIF31, which allows using a USB port.Note: For notebook computers that do not have an RS-232C serial port, connect the computer to the ZEN by connecting an OMRON CS1W-CIF31 USB-Serial Conversion Cable to the ZEN-CIF01 Connecting Cable.(2) The ZEN automatically configures its driver to match the port speed. If you do have a Windows serial port driver set up, then the possible ZEN baud rates are 4800, 9600, or 19200.

That port must not be used by any other software drivers (including Windows). You are in your Case 1.(1) Your computer must have at least one free real RS-232C serial port. I do not see the way to do that since ZEN SW uses a Windows COM port to communicate with ZEN PLC.That is not what I got from reading the ZEN Programmable Relal Operational Manual. Usually it is best to set Windows with a different port than the one used by the PLC. In other words, Windows has its setting, and the ZEN has its own port settings, which may conflict with the Windows settings where they both try to use the same COMM port.

If the ZEN is like many other PLCs (Allen Bradley SLC model, for example), the serial port settings in Windowsmayo not apply to the ZEN. The issue is that, in any case, needed or not, I cannot find the serial port setting in the PC that suits ZEN serial cable. Lancie1, thank you for your response!!Actually what I am looking for are the settings of the PC serial port (baud rate, data bits, parity and stop bits). Change the ZEN to STOP mode and re-execute the command.If the ZEN is protected, then a connection cannot be made.

It appears that the ZEN must use Com 1 or 2, and that the Node number set in the program must be the same as the Node number set on the ZEN.Also, look at the ZEN Help Error Messages:If the ZEN model type does not match the type set in the program, then connection cannot be made.If the ZEN is in RUN mode, then connection cannot be made. Can anybody help me on this? Sefcs,Look in the ZenTool Help files (copy attached for educational purposes), 'Transferring and Monitoring Programs', then 'Connecting the ZEN and Communications'. I have been using all the combinations of baud rates, parity, stop bits, etc, without success. I have performed this operation many times in the past but now I am having some difficulties since I cannot establish the connection between the ZEN support software and the PLC.I am still checking the cabling, drivers, etc.īut I do not remember the exact settings for the PC serial port and I cannot find it in any user manual. I am using the following setup:ZEN-10C3AR-A-V2 Omron PLCZEN-SOFT01-V4 Support Software (ver 4.14)ZEN-CIF01 Connecting CableUSB-Serial converter (third party)Windows 7 LaptopI want to download in the PLC a new version of the ladder program.
