COM: Unspecified error

I have a program that writes numeric inputs to the PLC. The program will not write the first 8 - 12 tags but then writes the rest of them (about 200). I am using the downloadAll command in RSView32 to perform this function. If I continue to run the download all, the information will eventually get into the PLC. Also, if I go to each numeric input and press enter the information is written. I get the errors: Can't write to tag XYZ followed by COM: unspecified error. Any ideas?

Try the above thread. Ensure that you are not writing to input tags to the PLC.

Hope this helps,

Thanks for the reply. Unfortunately, the thread did not apply. The issue is that I have other computer/PLC combinations that are running the same code without issue. This one is just acting funny. I ended up changing the button to set the focus on the offending information on the HMI and downloading that number and then incrementing to the next number. It is a brute force method, but it worked. Still would like to know that the actual fix is if you have any ideas.
