hello everyone. I need help. I have an x90cp174.48-00 controller. I have a project with the hardware configuration. I have previously unloaded this configuration. Previously, the project was written in AR version G4.34. As can be seen in the photo below. I have the AR version J4.93.
The controller was removed from the tractor. And there were plans to program it for other purposes. I set myself the goal of studying the project of this x90 controller and deleting this project from this controller. First, I uploaded the configuration via “identify hardware configuration online” and saved it on the computer. During the study, I decided to adjust the controller configuration settings in the project and started downloading it. I’ll show you the settings I’ve changed in the photo below.
Hi Yanis,
It sounds like you installed a new project on the X90 controller and overwrote the previous one, is that correct? And you’re now trying to connect to the controller in Automation Studio?
What are your IP settings on the ethernet ports? Is SNMP activated on any of the ports? You can see this information by right-clicking on the port in the Physical View and selecting Configuration. There are two ETH ports on the controller and so you can use either or both of them for an online connection, as long as they have a valid IP address.
Next, I will describe the process that took place when uploading my adjustments to the x90 plc.
Using the existing connection of my controller to the computer via an rj45 to m12 ethernet cable, I connected it to the controller via the IF2 ETH interface. And I started uploading my adjusted settings by clicking on Build (F7). The download started successfully, but during the download, the message "Target is being rebooted. Wait for reconnecton. The controller restarts and the LED displays show R/E green does not blink, RDY is not lit, S/E green does not blink and ETH green does not blink.
On this message " “The Target is being rebooted. Wait for reconnecton.” the download freezes and that’s it. I had to terminate the connection and a message appeared in the transfer to target window “Operation has been canceled for the user”.
Next, I reboot the controller. After startup, only three LED indicators light up on the controller, which I wrote earlier: “R/E green does not blink, RDY does not light, S/E green does not blink and ETH green does not blink.” And I try to search in the “online settings”, but the controller is not detected. I did not set the ip address filter.
Next, I tried to do a “reset” by pressing the Button next to the LED indicators, pressing them as per the instructions of their three methods. After that, the controller restarts and the LED indicators light up. R/E red does not blink, RDY org does not blink, S/E grn does not blink and ETH sometimes blinks green.
Hi Marcus Mangel
Yes, that’s right, I uploaded a new project, but as described above, I had a glitch. I checked the controller settings in the project tree and took the screenshot below. I have set these plc settings.
Thanks for the screenshot! I think that’s probably the issue. There is no static IP address in your project and so the X90 is waiting to receive an IP address from a DHCP server. Additionally, SNMP is deactivated which means it won’t show up in the Browse window.
The first step is to set an IP address (if that’s what you want). I’d also recommend activating SNMP for development as this will allow you to browse for the controller on the network. Then, you’ll need to re-transfer your project. There are two options for this:
- Connect the controller to a network with a DHCP server so that it receives an IP address, or
- Perform an offline installation using a USB stick
Thank you 
, I understand you. There is no possibility to work with DHCP yet. I will try later. And how to perform offline installation using a USB drive, can you explain which one is suitable for the x90 series PLC?
You’re welcome! I think most USB sticks will work for this, just make sure you pick one that you are okay with erasing. Here are the steps:
- Format your USB stick as FAT32
- In Automation Studio, go to Project → Project Installation → Offline Installation. Select your USB drive in the dropdown
- After the package generation is complete, insert your USB drive into the X90 (the USB port is right under the removable cover)
- Next to the USB port is a tiny button. You’ll need to put the X90 into BOOT mode by giving this a short press (less than 2s) followed by a long press (more than 2s).
- The controller will reboot once or twice and eventually end up in RUN mode after the installation. You should then be able to connect from Automation Studio.
