Indirect Addressing In Studio 5000 V32 (Simple State Logic Control)

A Studio 5000 Indirect Address is just like the name says, indirectly tied to another data source in a way that is often confusing in PLC programming.

Our video here will break down indirect addressing in a simple way to provide clarity to this mystery...ha

Let's talk about the data behind the indirect address process.

If you have a data type of a DINT that is pointing to an array of data like a DINT[50] then the DINT will point to the section of the array that is in the original DINT.

Example:
StateMachine[RequestedState]

The tag in the brackets is a single DINT that takes the value of itself then points to the location in the array of data for the tag outside of the brackets.

If the tag StateMachine is a DINT of 50 then it is the array of data.

This makes the tag RequestedState a single DINT

So if the tag RequestedState is set to a value of 23 then it will point to the array DINT of StateMachine[23] to get the values of what is inside of that DINT in that array.

After explaining it in text form, you see why making a video is slightly more helpful.

I hope this video helped you.
