What determines the address of PLC I/O points?

Thread Content

How are the addresses of PLC I/O points determined? Where can these addresses be found in the host computer? How can process symbols and process tag numbers be identified?

This address is calculated based on the arrangement of the hardware; digital signals correspond to a value of 1 while analog signals correspond to a value of 2. It can be found in the database of the upper-level computer

How can I see the process symbols and their corresponding tag numbers?
