Greetings! I am currently working on implementing Indirect Addressing for bits within an INT. With a total of 11 digital inputs at my disposal, my goal is to assign the value of each DI to an INT variable. While referencing tutorials on Indirect Addressing in Studio 5000, I found that they primarily utilize the MOV instruction to populate arrays. However, MOV is not equipped to handle writing values to an array of BOOL[32] or specific bits within an INT. Essentially, I am looking to update the state of the INT based on the active digital inputs (e.g., DI 1, 3, and 7 activated should result in the corresponding bits in the INT being set to 1). The update needs to occur every 500ms. Is there a feasible solution to achieve this task?
The method of using either COP or XICs paired with OTEs depends on the data format of your DI, which can vary depending on the type of IO.
lmscar12 recommended utilizing either COP or XICs paired with OTEs, depending on the data format of your Digital Input (DI) signals. While COP may not be compatible with BOOL data, XICs and OTEs can still be employed. For the specific requirement of transmitting the state of 11 DIs as a single analog output value, an INT data type is needed to consolidate the inputs.
When manipulating a bit in your program, such as using the XIC instruction, it's important to understand the task at hand. Double-checking your input is crucial to prevent any errors that could impact the controller's performance. It's easy to inadvertently blame the controller for mistakes when not paying close attention to your actions.
When Rookie0810 attempted to use Control Output Pointer (COP) with Boolean data types, they encountered an issue. Instead, they are utilizing eXamine If Closed (XIC) and Output Energize (OTE) instructions, but require an Integer (INT) to store the status of the 11 Digital Inputs (DIs) to transmit it to a singular Analog Output. To achieve this, simply use the XIC DI OTE INT.x method, where INT.x represents one of the 16 available bit-level addresses within the Integer file.
Are you working on this task in Studio 5000 or RDLogix? If so, @dmroeder's solution should help. Consider utilizing a loop for efficiency or tackling it head-on with 11 XIC/OTE pairs for a brute force approach.
Indeed, you have quite a technical query here. For your indirect addressing issue, implementing a BTD instruction sequence may be more suitable. This allows for bitwise manipulation of the INT variable based on the state of your digital inputs. Instead of MOV, what you can do is to use an array of XIC instructions linked to your digital inputs to trigger individual OTE instructions, each targeting a bit in your INT variable. Now about the update period, a simple timer can be utilized to refresh the INT value every 500ms. Remember, it's crucial to make sure your program can loop without exceeding this timing interval to ensure consistent outputs.
Hey there! I'd suggest using the BTD instruction (Bit Field Distribute) which is specifically designed for working with individual bits within a word. This instruction can rearrange bits between a source and a destination. Should you decide to use this, you will need to assign your digital inputs to a single INT (each bit representing one DI), which will serve as your source. Then, you can use the BTD instruction every 500ms to update the state of your destination INT. This approach will allow you to target specific bits of the INT, thereby reflecting the state of your activated DI. Check out the Studio 5000 documentation for more detailed steps on using BTD instruction. I hope this helps!
Hello! For your task, I would suggest taking a look at the BitSet and BitClear instructions instead of MOV. You can use them to modify individual bits within your INT variable based on the state of the digital inputs. Create a loop that executes every 500ms and iterates through your group of digital inputs. In each iteration, check whether a particular input is high or low and accordingly use BitSet/BitClear for the corresponding bit in your INT variable. This could be a more direct approach to achieve your goal within Studio 5000.
It sounds like you're on the right track. If you're working with Studio 5000 and essentially want to map digital inputs to certain bits in an INT, then you might want to consider using the bit shift and bitwise OR operations. You could loop through your digital inputs and, for each one that is activated, shift the value '1' to the left by the index of the input. Combine these shifted values using the bitwise OR operation to form your INT. Tie this logic to a timer to have it run every 500ms as required. Make sure to reset your INT at the beginning of each cycle to ensure you're working with a clean slate.

Answer: Answer: To assign digital input values to INT variables using Indirect Addressing, you can implement a solution where the state of the INT is updated based on the active digital inputs. This can be achieved by monitoring the digital inputs and setting corresponding bits in the INT variable to 1 when certain digital inputs are activated.
Answer: Answer: While the MOV instruction is commonly used to populate arrays, it may not be suitable for writing values to an array of BOOL[32] or specific bits within an INT. You may need to explore other instructions or methods tailored to handling specific bit manipulations within INT variables.
Answer: Answer: Updating the state of the INT variable every 500ms ensures that the system remains responsive to changes in the digital input values. This frequent update interval helps maintain real-time synchronization between the digital inputs and the corresponding bits in the INT variable.
Answer: Answer: To efficiently handle scenarios where multiple digital inputs activate different bits within an INT variable, you can create a logic that dynamically updates the relevant bits based
