6.4 Configuring a tag for address multiplexing
Introduction
Using address multiplexing, you can use a single variable to access a multitude of memory
locations within the PLC's address range. You read and write to the addresses without
defining a variable for each individual address. This efficient method allows you to process a
large amount of data.
Example of a procedure using R parameters as a basis
1. Create a local "index" variable.
2. Create a variable with a connection to a control, and in area C and in the RP block, select
the R parameter variable.
3. You can make a selection from the operator control to the right next to the input for the
parameter number.
4. Select HMI_variable followed by the "index" variable.

Result
By changing the "index" variable during the runtime, another R parameter is accessed.
