Selection of Data Tables

Recommended Posts

  • 2 weeks later...

This is a common practice in Siemens Step7 but is completely UN-necessary in Visilog.

The DataTable is defined in the function that accesses it, so every function has the data table for which it is intended explicitly defined within the instruction.

In Visilogic, no data table is "open" after the function is done. They are only open during the function. And each function must explicity define which table is being used for that function.

In this way several data table functions can be used on the same rung / network.

Copy row from Data table 4 , row 3. Or the symbolic equivalent.
