Hello! Have you experienced a problem with the SLC 5/05 where the battery-backed clock (S:37 - S:42) resets to zero? This issue may occur when the SLC loses power and the memory is cleared. Any tips or recommendations on how to address this would be much appreciated!
One way to stop the clock function is by writing zeros into it, or by choosing not to activate it at all. By syncing the clock with your computer using RSLogix 500 software, you can ensure that it accurately keeps time even when the power is off, as long as the CPU battery is functioning properly. This feature allows for convenient timekeeping without interruptions.
Absolutely, I had a similar issue with the SLC 5/05's battery-backed clock. What worked for me was implementing a startup routine to set the PLC clock from an HMI or a network time server each time the PLC starts. It's just a workaround, but until there is a permanent fix, it can help prevent losing your timestamp data. Also ensure your battery isn't due for a replacement; that might factor into this issue too.
Yes, I've experienced this with the SLC 5/05 in the past! One approach that I found helpful was to use a PLC program that automatically sets the RTC whenever the PLC starts up. To do so, you need to write code that checks whether the S:37 value is 0. If it is, the program will assign a predetermined default timestamp. Nevertheless, this is a temporary fix and ultimately, I'd recommend you to check the battery, it might need replacement.
I've encountered this issue before with an SLC 5/05 system. It seems to be relatively common whenever there's a loss of power. A good workaround I found was to write a logic that checks time and date, and if they are zero or invalid, the logic would then reload a valid date and time from an integer file. This way, you'll always have an accurate timestamp even after power interruptions. Hope this helps!
Hey there! I’ve seen the SLC 5/05 clock reset issue before, and it can definitely be frustrating. One thing I've found helpful is to check the battery and ensure it’s not just weak but also properly seated in the module. If the battery is fine, consider using the "Set Time" option in the programming software after restoring power to help prevent the clock from resetting again. Also, implementing a backup power solution could help maintain the memory during outages. Good luck!
