Hello, I am currently utilizing Studio 5000 along with an emulator. I have created a straightforward program where an XIC Contact should energize an OTE in a single rung. However, for some unknown reason, the XIC is not energizing my OTE. The program is in run mode without any errors or warnings. I have included the routine in the main routine using JSR. The tags utilized are only within this routine, and are the only ones in the program. Typically, I do not work with emulators, but I have verified that the configuration is correct.
Gal_Tom, could you please include a screenshot? This visual aid will be beneficial in enhancing our understanding. Thank you.
RAYBRITO requested for Gal_Tom to include a screen capture as it would be beneficial and enhance the experience. This feature could greatly assist users in better understanding the content.
It is highly probable that the Programmable Logic Controller (PLC) is executing the commands you input, even if they are not aligning with your desired outcome. The PLC operates based on the instructions it receives, disregarding your intentions. To rectify this issue, you must identify the discrepancy between the current operation and your expectations. Begin by performing a simple test to confirm the evaluation of the rung. Create a tag labeled "arealand" and modify the rung with the following code: XIC Conv_ONS_1 BST coil_1 NXB ADD areal 1.0 areal BND. Alternatively, you can use the code: XIC Conv_ONS_1 BST coil_1 NXB XIC coil_1 ADD areal 1.0 areal BND if you doubt the PLC's compliance with your instructions. Share the outcome in this forum, remembering to reset the value of "arealand" to 0.0 in the Integrated Development Environment (IDE) periodically.
Additionally, please provide the entirety of the program, preferably in a PDF format, showcasing every instance where the variable 'Conv_ONS_1' is being utilized.
Gal_Tom mentioned that they are utilizing Studio 5000 with an emulator to program a simple ladder logic. Despite setting up an XIC contact to energize an OTE output on one rung, the desired outcome is not achieved. The program is free of errors or warnings and is running in the correct mode. The routine is called from the main routine using JSR, with tags solely used within this routine. It is uncommon for Gal_Tom to work with an emulator, but configuration settings were verified to be accurate. Upon closer inspection, it appears that there may be additional ladder files and the same bit is used elsewhere as an output, which stays deactivated at the end of the scan cycle. Sharing the .ACD file could provide more clarity, but based on the provided information and screenshot, this could be the likely issue.
It appears you've checked most of the usual suspects, so kudos for your thoroughness. One thing comes to mind: sometimes, when using an emulator, the S:FS (First Scan bit) might be the culprit. This is a special bit that remains set for one scan after the processor switches from Program Mode to Run Mode. If your OTE is somehow connected to this, it might be causing the issues you're experiencing. Double-check if that's the case. If this doesn't help, consider sharing your ladder logic, someone might spot something you missed.
Hi there! Your issue could be stemming from a variety of things. You might want to start by checking the status of the XIC contact in the program. It's important to remember that the XIC instruction will only turn on if the physical or virtual bit in the PLC memory it’s associated with is on as well. Try manually forcing the XIC input ON in the emulator and see if the OTE lights up. If it doesn't, there might be a deeper problem with your program. Alternatively, look into your JSR instruction; if there's an issue with your subroutine, JSR might not be executing the routine properly. Hope this points you in the right direction. Good luck!
It sounds like you've covered a lot of the potential issues, so good job on the troubleshooting so far! If your routine is set up correctly and your tags are unique, it might be worth checking the status of your XIC contact. Ensure it's not being overlapped by another command somewhere else in your program which would prevent it from energizing the OTE. If this doesn't resolve the issue, you could try simulating with different emulators to see if there's a possible software compatibility issue at play. Don't forget to keep us posted!

Answer: Answer: There could be several reasons for this issue, such as incorrect configuration settings, tag scope limitations, or a programming error. Make sure to review your settings and code carefully to identify the root cause.
Answer: Answer: You can start by checking your program logic, verifying tag usage and scope, confirming configuration settings, and ensuring there are no errors or warnings in your program. Additionally, you may want to simulate different scenarios to pinpoint the issue.
Answer: Answer: When working with emulators, ensure that your program logic is correctly implemented, all tags are properly scoped within the routine, and that the emulator is configured accurately to mimic the real-world environment. Double-checking these aspects can help in resolving OTE energizing problems.
