Hello, I am currently using Unity Pro XL to establish a connection with my PLC. While the connection is successful, I am encountering difficulties when trying to connect the I/O modules, specifically with the processors TSX P57 2634M Premium Schneider and TSX RKY 8 rack type. When attempting to open the configuration for the I/O modules, an error message stating "unable to change connection state" is displayed. The only action I am able to take is to close the configuration. Any assistance on resolving this issue would be greatly appreciated.

Welcome to the forum! Are you wondering how to find the firmware version of your PLC? The firmware version is typically displayed in the online view, on a sticker attached to the side of the PLC. However, you can now check it without removing any cards. If you have an older PLC with firmware version 2.3 or similar, a simple solution is to use a serial cable such as the PCX1031. Alternatively, you can utilize the XIP-driver, which can be found on the Unity installation DVD. Check your PLC's network configuration to locate the XIP address assigned to it (usually 0.1 by default). On the PC side, configure the XIP driver to match this address range (e.g., 0.63), then input your PLC's IP address (e.g., 192.168.1.10) and bind the XIP driver to the correct network on your PC. In Unity, enter the IP address {0.1} and select TCPIP-type -> Connect. With XIP, you should be able to access configurations in the online view. It's worth noting that newer Unity P57 firmwares may not require the XIP driver for TCP connections, although this is not confirmed.

Hi Lare, I am currently using version 2.3 firmware on my Premium PLC. Unfortunately, I do not have the XIP-Driver for it. Are there any alternative solutions available?
1. If you have misplaced the installation DVD containing the XIP driver, you can reach out to Schneider's technical support for a link to download the XIP driver. 2. If you have the serial cable PCX 1031, you can use it instead of the XIP driver. 3. You have the option to make offline configuration changes and perform a full download to the PLC. However, keep in mind that a complete project download will briefly halt the PLC and reset all bits. Make sure to save PLC data to a file before the download and transfer it back after. 4. Upgrading the PLC firmware is a time-consuming process (lasting at least 30 minutes) and can result in needing to purchase a new PLC if errors occur during the upgrade.
When it comes to accessing I/O configuration on TSX P57 CPUs after upgrading to Control Expert, the XIP driver plays a crucial role. In case the installation DVD containing the XIP driver is misplaced, reaching out to Schneider's technical support for a download link is the next best option. Alternatively, if you possess a serial cable PCX 1031, the need for XIP is eliminated. It is possible to make offline configuration changes and perform a full download to the PLC. However, a complete project download briefly halts the PLC and resets all its bits. To safeguard PLC data, back up the information before the download and restore it afterward. Upgrading the PLC firmware is a time-consuming task, taking a minimum of 30 minutes. In case of any issues during the upgrade process, a new PLC might need to be purchased. Can anyone advise on the firmware version required to avoid the XIP driver necessity when using a TCP/IP connection with both V2.3 and V2.5 CPU versions?
I'd suggest taking a look at firmware compatibility first. Sometimes, such issues can be related to outdated firmware. Unity Pro XL should come with a version checker. If you haven't done so already, ensure that your TSX P57 2634M and TSX RKY 8 have the latest firmware updates. Another possible workaround to this may be to delete and re-enter your I/O modules in Unity. This kind of "hard reset" sometimes clears out any configuration issues. If all else fails, maybe try reaching out to Schneider's support. They should be able to provide some more specific guidance. Hope you manage to get it sorted out!
It sounds like you're grappling with a frustrating issue! A common fix for the "unable to change connection state" error in Unity Pro is to make sure that the I/O modules are properly powered and that all connections are secure. Sometimes, a simple restart of both the PLC and Unity Pro can clear up temporary glitches. Additionally, double-check your project settings and ensure that the configuration matches the actual I/O modules you're trying to connect. If you’re still stuck, consider checking the firmware versions for both the PLC and the modules, as compatibility can sometimes cause these types of problems. Good luck!
It sounds like you're running into a common issue with PLC configurations! Have you checked if the firmware of both the PLC and the I/O modules is up to date? Sometimes compatibility issues can arise from outdated software. Additionally, ensure that the I/O modules are configured correctly in Unity Pro XL and that the communication settings match those of your PLC. If everything looks good there, try restarting Unity and your PLC to reset any lingering connection states—sometimes that does the trick!
It sounds like you're running into a frustrating issue! Have you tried double-checking the communication settings and ensuring that all necessary drivers are up to date? Sometimes, connectivity problems arise from mismatched settings or outdated software. Also, restarting both Unity Pro and the PLC might help reset any hiccups in the connection. If those steps don’t work, looking into the specific firmware versions for your PLC and I/O modules can sometimes reveal compatibility issues. Good luck!
