Getting the 499 0x1000 alarm found the following in the forum but no help. It means you are calling an address with the C-more that has not been defined in the PLC. Go to the C-more error screen and it will show what address is causing the problem. But thing is I can edit the tag and the PLC change's Error Info as follows: COM3,DEV001,RD F11:128,112BYTE ERROR CODE PLC-499 I have verified the tag in the editor and it look's right, It's a Floating Point Type F Address 11:128 PLC Table is 150 in length... I also renamed tag to see if it followed and it does. I did find i had a couple tags that went past the F11:149, changed the table to 180 and everything work's, went back in and verified the error I was getting and it was telling me to look at the wrong tag, Minor Issue, Should of been telling me F11:150, F11:151, etc was the tag in question... Thanks Jason

C-more attempts to optimize the read requests into data blocks. If addresses are close enough together they will be read using the lowest address as the starting address with a block size which allows for several other tags to be read inside one request. Since your F11:151 is only 22 words away from F11:128 my expectation would be that the entire range was requested at once. In this case the request was rejected because your PLC data file size is not large enough and C-more reports the error of the start address of the block request. Why did you have tags in C-more which point to addresses which don't exist in the PLC?
