What kind of names are given to PLC memory locations for storing information?

The correct designation for PLC memory locations used to store information is symbolic names. Symbolic names allow programmers to use easily recognizable and meaningful identifiers for memory addresses, rather than relying solely on numeric addresses. This practice enhances code readability and maintainability, making it easier for programmers to understand the purpose of a variable or memory location at a glance. Utilizing symbolic names helps reduce errors and clarifies the intent of the code, as developers can quickly identify what stored data represents in the context of the application.

Using other naming conventions like text-based or numeric does not provide the same level of clarity and efficiency, as these approaches can obscure the function of a memory location and complicate troubleshooting and future modifications. Graphical names are not typically used in PLC programming and do not fit the conventional naming schemes associated with memory locations in programmable logic controllers.
