Float error on PanelView 300

[ladderlogix]

Hi,
I'm using a logix5550 and a panelview 300.
When trying to read data such as IEEE Float/Real and alarms, I have the following error:
683 File access error.
Does any one know how to fix it?
Many thanks

IIRC the "File Access Error" means that the PLC/SLC Compatable File you are referencing doesn't exist, or the element is out of range.

Trying to read F27:100 for example if F27 isn't defined, or if it only goes up to element 99.

Are the file-mappings correct (Logic | Map PLC/SLC Messages...)?

Are you overrunning the bounds of the tag array referenced?


More details please, including the actual tag address as you've defined it in the 300 and in Logix5k
