Function Block VISUSET

The Function Block VISUSET controls the communication with the visualization.

Note: If scaling is performed, this must be done on both sides of the Function Block if both sides communicate via the same address.

WARNING: Never set two VISUSET or VISUDTSET with the same database in succession using SET. This leads to high unnecessary load on the PLC. Instead, use logic before the input SET.

Database

The Database DB defines the variable for communication with the visualization. The variables of the database cannot be accessed directly as with a normal database.

Input ➜

If the value at the input changes, it is transferred to the visualization and to the output ➜. However, here the input is compared with its own internal variable. This way this Function Block can be used multiple times in the same element.

Input DIS

If the input is true, it deactivates the transmission from the input ➜ to the visualization and to the output ➜. The internal markers are not written in this case. This means that after deactivation, the values will be compared again and possibly transferred.

Input SET

If the input is true, it forces the setting of the value at the input ➜ to the visualization and to the output ➜. It has priority over the input DIS.

Output ➜

The last changed value is present at the output. This can come from the visualization or the input ➜, unless blocked by the input DIS.
