Hi my dear, 

After using this functions blocks I'll be able to  send the hours of working of the burner in a display? For me is  better also have the total of hours in an display for that the  operators could have all information!

Thanks in advance

I hope useful

Hi dear

I have followed what is in the chapter 6 and I made it following the steps, it works very well, but the only problem right now  is that I want to have the hours of three different boiler with its different burner, so I created a function for accumulate the hours, but once I call it for calculate in another burner it gives the same value for the three burner! I'm thinking to create this function into a function block ! Is it possible? Help me please

"is like this, e.g  FC1- function run-time meter is being called into FC2- general data , for burner 1, 2, and 3 gives the same value!"

best  regards

 Hi 

It's better to write a function for this job (for example FC1) and call in OB(cyclic) 3 times for your burner,
