"...FactoryTalk View SE Graphics supports single precision floating point values, and by default only provides for 6 significant digit accuracy. Note: digits displayed before the decimal point count as part of the total significant digits. Any digits displayed after the 6 significant digit are approximations only and should not be treated as significant..."
I am working on an ME V11 project and require 8 digit accuracy for several display and input fields. These are all PLC REALs with four digits before and four digits after the decimal point.
I can create two DINTs and HMI fields for each of these and then merge them in the PLC, but this seems unnecessarily cumbersome for both me and the machine operators.
In typical Rockwell fashion, the KB article lists single-precision/6-digit accuracy as the "default", but gives no indication of how to change the default or if this is even possible. I assume it is not. Has anyone found any other workaround for this limitation?
