Procedure

The following services should be installed and running for the USB and Direct Ethernet utilities to function correctly. These are used for instance to connect Sysmac Studio and CX-Programmer to CPUa and NX couplers via USB, as well as the direct cable ethernet connection to controllers.

Note the above screen capture shows the three services that should be installed. The status of all three are Running. This is the required status. In order to install services, the .Net command installutil.exe must be used. Note that there are multiple versions of this installutil.exe which exist in different .Net Framework folders according to version. The lowest version existing was arbitrarily used for this procedure. If the procedure fails, perhaps consider using a different version.

The Omron system utilities are located in the directories as follows;

The Omron USB related services;
- C:\Windows\SysWOW64\Omron\PppService\Omron.Cxmw.Modules.Ppp.PppService.exe
- C:\Windows\SysWOW64\Omron\SerialService\Omron.Cxmw.Modules.Serial.SerialService.exe
The Omron Direct Ethernet utility related service;
- C:\Windows\SysWOW64\Omron\autoip\Omron.Cxmw.Modules.AutoIP.AutoIPService.exe

Windows system utilities are installed using the installutil.exe via the command prompt. These are located in subdirectories of the folder C:\Windows\Microsoft.NET\Framework\. Note do not use the C:\Windows\Microsoft.NET\Framework64\ path (this path was tested with Windows 10 64 Bit and Sysmac Studio 64 bit and found that the installutil.exe in the first path works but the second does not work). Use Windows explorer to search for instances of installutil.exe in the C:\Windows\Microsoft.NET\Framework\ folder.

Right click on an instance of the utility and select Open File Location as per below.

Now click in the path text and copy the text (control C).

Open a Command prompt window as Administrator.

Type cd and press control V to paste the above path.

Then type installutil.exe and copy and paste one of the three services listed.

For instance, the commands to install the direct ethernet utility would be, as per the previous example (which is machine build specific) as follows;

In command prompt (in Administrator mode)

cd C:\Windows\Microsoft.NET\Framework\v4.0.30319
Installutil.exe C:\Windows\SysWOW64\Omron\autoip\Omron.Cxmw.Modules.AutoIP.AutoIPService.exe

If an exception error occurs, the service has not been loaded. However if the result is similar to the following the abbreviated result, the service has been installed.

Microsoft (R) .NET Framework Installation utility Version 4.8.3752.0
Running a transacted installation.
Beginning the Install phase of the installation.
………
Service OMRON_EDC_Manager has been successfully installed

Now the service must be started manually, unless the machine is rebooted.
Open the Windows service by Ctrl+Alt+Del and select Services tab. The services should now be listed. Right click and select Run to start the services.

Validate that the service status is Running.

Uninstalling an OMRON service

Note the command to uninstall a service is for example

Installutil.exe /u C:\Windows\SysWOW64\Omron\autoip\Omron.Cxmw.Modules.AutoIP.AutoIPService.exe
