Research direction

Start with the plc4j implementation and its S7 protocol handling, then review how the current address-based value reads work. Compare that flow with the linked symbolic-addressing information and identify the project entry points involved. Done means plc4j can read Siemens PLC values by symbolic names as well as legacy addresses.

Description

java S7
What would you like to happen?

Problem or use case

Read the "Symbolic Names" from the Siemens PLCs instead of defining the "Addresses" of the values in the PLCs. Reading addresses is considered a legacy method to read values but it seems plc4x only supports this method

Preferred solution or suggestions
Implement "symbolic addressing" of values in the Siemens S7 PLCs.
