Variable value behaviour at function blocks input is strange?
Greetings, Sir can you guide me to resolve a problem that i am facing at trend acquisition functional block input value? The function Block of trend acquisition is being provided a value of 4065.313 at its first input through a variable but when we take cursor at input connecting line of block and variable, we see a value of 2.438465, which is a wrong value and block is showing that wrong value (2.438465) on trend display instead of 4065.313 (Correct value). i am facing Same problem with an input value of another function Block of analogue output. I have attached the pictures of these functional blocks in commissioning mode for further clear description of my problem. This is about freelance software version 2013.
Possibly the variable 'PAB01CL101' belongs to a different Freelance controller as the Trend FB ? This would explain the difference, as tooltips get there data from the data source. If so, please check if all 3 participants ( the controller who feeds the variable + the controller with the trend + the CBF ) have the exact same Freelance revision (servicepack and rollup). You find that build info on controller network-diagnosis and on CBF PC windows , installed programs. In addition check if all components of your Freelance project are green-colored and loaded.
