In Simatic Manager, I am utilizing the System Function Block SFB38 for the High Speed Counter. This block comes with input parameters such as ENPRES, COMPEN, COUNTRESET, and SET_COMP. According to the manual, digital inputs 126.0 and 126.1 are to be used for counter A, while inputs 126.2 and 126.3 are assigned to counter B. My query revolves around the connection between digital inputs and counter values. How do we determine when to utilize inputs 126.0 and 126.1 versus inputs 126.2 and 126.3? Is there a way to identify which input value corresponds to counter A or B? (A related screenshot is provided for reference.)
If you are utilizing an S731x IFM processor, follow these steps.

Are you unable to see a count after enabling predefined looks? Check the "true" status in the vat table.
I am able to see a count when I use inputs 126.0 and 126.1, but no count is displayed when I use inputs 126.2 and 126.3. Why is this happening? How do I link my inputs to the counter to resolve this issue?
The choice of either digital input group (126.0/126.1 or 126.2/126.3) to use will strongly depend on the specific application in your automation process. If your process necessitates two separate count functions, for example, you'd use both groups, each group assigned to its own counter (A or B). On the other hand, if you only need one count function, you'd just select one digital input group for the corresponding counter. As for identifying which group corresponds to which counter, that's all defined in your setup - you assign the grouping, so you will be fully aware which one is for counter A and which is for counter B.
To determine which inputs to use, you need to look at the specific task or function you're trying to accomplish. If you're working with Counter A, you'll utilize inputs 126.0 and 126.1. For Counter B uses, you'll engage inputs 126.2 and 126.3. They're assigned separately to maintain precision and prevent interference between the counters. Usually, you'll find this division of input values useful when you're running two simultaneous count functions, each requiring specific and isolated sets of inputs. I'd recommend spending some time to map out your requirements, then it'll be easier to decide between Counter A or B. Don't forget to deep dive into the Simatic Manager's manual for clearer instructions and use-cases related to your task.
Great question! The distinction between inputs 126.0/126.1 for counter A and 126.2/126.3 for counter B typically relates to the specific application or functionality you’re implementing. For example, if you’re monitoring two different processes or devices, you’d assign each counter to the respective input signals from those devices. To determine which input value corresponds to which counter, you can simply reference the input assignments in your PLC configuration or during the setup phase in the hardware configuration. It’s also helpful to check how each counter is being used in your application logic—sometimes, naming conventions or comments in your code can clarify which inputs are tied to which counter.
Great question! The distinction between using inputs 126.0 and 126.1 for counter A versus 126.2 and 126.3 for counter B typically hinges on how you've configured your application and what signals you expect to count. Essentially, you would assign inputs based on the specific events or conditions you want each counter to track—like different sensors or machinery operations. To determine which input correlates with each counter, you can check your project’s configuration or look at the wiring used in your setup. Additionally, monitoring the output values of each counter during operation can also help clarify which input is affecting which counter. If you're working with a dual-counter scenario, it might be helpful to label your inputs clearly in your documentation for easier troubleshooting later on!
Great question! The choice between using inputs 126.0 and 126.1 for counter A versus 126.2 and 126.3 for counter B generally depends on your specific application requirements. For instance, if you're monitoring two different processes or components, you'll assign inputs based on which counter you're using for each specific task. To identify which input corresponds to each counter, it’s crucial to refer to your project documentation or configuration settings to see how you’ve defined those counters in your application logic. Additionally, tracking the status of these inputs during runtime should help clarify which signals are affecting which counter. If you're using a visualization tool or HMI, you might also label them accordingly for easier reference!
Great question! The inputs 126.0 and 126.1 are specifically linked to Counter A and are typically used for counting events or pulses that you want to track with that specific counter setup. Similarly, inputs 126.2 and 126.3 will correspond to Counter B. To determine when to use each set of inputs, you need to consider the specific process or event you're measuring. For example, if you have two separate processes or sensors you want to monitor simultaneously, Counter A can track one while Counter B tracks the other. Always make sure to refer to your project's logic or the application requirements to see which counter setup fits best for your inputs. Checking the connection wiring or logical organization in your program can also help clear up which input corresponds to which counter!
