4.4 User program blocks
The user program consists of the following blocks:

"Filling" function block (FB 12)

"HMI" function block (FB 13)

"tags" data block (DB 10)

"Filling" function block

4.4.1
The "Filling" FB is used for filling a container with a selected wall anchor type.
For this purpose, the scale is tared to neutralize the weight of the container.
The recipe data record of the wall anchor type to be packaged is loaded. The
product, made up of pieces and individual weight of a wall anchor, results in the
weight setpoint. The "Filling" FB starts the filling process by opening the two
sliders. When the specified weight limit is reached, one of the sliders closes, and
packaging is slowed down. When the setpoint is reached, the second slider also
closes. The weight reached is compared with the tolerance data from the recipe
data record and evaluated. The packaged products are continuously counted and
therefore receive a clear assignment.
The call of the "Filling" FB is in OB1.
