Hello everyone, I am experiencing an issue with a machine operating on a 1756-l55 rack 0 and multiple 1794-asb rio racks connected to it. I am attempting to replace a module in one of the remote racks, but the system is not accepting it. Although I have removed and added the new module in the controller organizer, it only prompts me to select between digital or analogue, with no option to specify the exact module type. I have not been able to find any information on how to input this specific module information into the PLC. I have replaced a 1794-irt8 with a 1794-ob8ep, and now the outputs are randomly flashing in a sequence. Any assistance would be greatly appreciated. Thank you. PS: using old rslogix 5000 v16 version.
Are you currently utilizing a 1756'DHRIO or 1756-RIO module in your system? It is crucial to ensure that you have properly reconfigured the MSG instructions for the specific module space of the DHRIO to avoid any issues with output activation. If you are using an RIO module, have you adjusted the module settings in the RIO adapter table as necessary? Proper configuration of these modules is essential for smooth operation and accurate data transfer within your system.
Robertmee inquired about the use of a 1756'DHRIO or 1756-RIO module, asking if the MSG instructions were properly reconfigured for that module space. Failure to do so can result in the module config write of the previous input module turning on the outputs. If using an RIO module, it is crucial to reconfigure the module in the RIO adapter table. The existing MSG instructions in the program were identified as the cause of the issues, and after deletion, the outputs are now working efficiently. Thank you for your help.
Hey, the swapping issue you're having seems to be related to your RSLogix 5000 v16 version, it might not be supporting all the system modules you're trying to use. Upgrading the firmware might be a solution. Additionally, remember to check that you are matching each module with the correct slot. However, the randomly flashing outputs are concerning. They typically signify some sort of configuration issue, most commonly a mismatch between the configured I/O and what's installed physically. Make sure to review your module configuration in RSLogix after swapping and double-check your wiring as well.
Hi there, it sounds like you're having a bit of a challenge with your PLC setup. It might be an issue with RSLogix 5000 version you're using. Unfortunately, the older versions like v16 may not fully support certain newer modules. If an upgrade is not possible, one workaround you could try would be setting it up as a 'generic' module and manually inputting the requested information. Otherwise, you might need to upgrade your RSLogix 5000 software to a later version that has an established compatibility with the module you're trying to install, specifically the 1794-ob8ep. Hope this helps!
Hi there, seems like you're caught in a bit of a pickle. It's crucial to remember that in 1794 IO system, modules override PLC configurations. You may find that the PLC isn't recognizing the new module because according to it, the old 1794-IRT8 module is still configured there. You'll need to delete this old configuration from your PLC. After that, add the part number of 1794-OB8EP in your RSLogix 5000. Make sure you match the slot number correctly with the RIO mounting rack. Given that RSLogix 5000 V16 is a fairly old version, there could also be compatibility issues at play. It might be worthwhile to consider updating your software too. Good Luck!
It sounds like you might be running into a compatibility or configuration issue with RSLogix 5000. When replacing I/O modules like that, it's crucial to ensure that the new module is not only physically compatible but also that the proper configuration settings are applied in the software. Have you tried using the "Add Module" function instead of modifying it in the controller organizer? That can help ensure the correct module type is recognized. Additionally, double-check that the module you're adding is supported by your current version of RSLogix, as sometimes older versions might lack recognition for newer modules. If the outputs are flashing randomly, it could also be an indication of incorrect wiring or misconfiguration in the module setup. Let's troubleshoot this together!
It sounds like you're running into a common issue when swapping modules in a RIO setup! First, make sure that the new module you’re installing is compatible with the existing configuration. Sometimes, the controller needs to be explicitly told about the type of module being added, especially if the new module is classified differently (like digital vs. analogue). Since you mentioned RSLogix 5000 v16, check if you have the correct add-on profile for the 1794-OB8EP imported into your project; you might need to download it if it's not there. Also, ensure that the I/O mapping is correctly configured in the controller. If the outputs are still flashing randomly, it could indicate a communication issue, so double-check your network connections as well. Good luck, and let us know how it turns out!
It sounds like you're running into a common issue with module replacement in RIO racks. Since you're using RSLogix 5000 v16, make sure that the new module is added correctly in the I/O configuration and that the module type is set correctly in the controller's setup. Sometimes, it helps to double-check the wiring and ensure that the new module is seated properly in the rack. Since you've swapped a digital input module for an output module, you might also want to verify that the corresponding I/O points are configured properly in your program; those random flashing outputs could be due to mismatched settings. If you’ve confirmed everything but still have issues, consider restarting the system or the project to see if that resolves the problem. Good luck!
It sounds like you're running into a common issue with module configuration in RSLogix 5000, especially with older versions. When replacing a module like the 1794-IRT8 with a 1794-OB8EP, you need to ensure that the new module is properly configured in the controller's I/O tree. Sometimes, you might need to manually input the exact module type after it's added. Try checking that the module name matches the expected type and make sure the firmware compatibility is in check too. If the outputs are flickering, it might indicate a communication issue. Ensure all wiring is correct and the RIO configuration is set properly in the system. It might also help to restart the system after making the changes. Let us know how it goes!
