Hi ENgr,

There are a lot of ways to solve this.

The easiest way of doing it is to make 100 move instructions including a compare instruction in a FB.

Just compare the actual level with the level corresponding to the volume and move it to the output of the FB.

See the attached example.

But why are you using a sounding table ? isn’t there a formula to calculate your volume ?

The 1200 also have a Math function called “CALCULATE” here you can easily input the complete formula to calculate the volume of your tank.

The option u suggest is called “indirect addressing” you could search the forum for things like dynamic (variable) any pointer.

But for just 100 value’s I suggest you to use 1 of the first options if you don’t have knowledge about that and want to have it done.

Yes huggy_d1 has the best solution to fill your needs :D

But don’t forget that the Peek is standard Byte addressed, so multiply your Level with 2 when you’re going to use data type INT in your DB.

And don’t forget to use a standard DB instead of the Optimized for your sounding Table.

I made a demo project V13 (update 6) see attached.
