I’m a complete beginner. I’ve tried to create several flow meters by following others’ examples; the signal from these meters is 4-20mA, and the hardware settings are correct, but there’s no output. As shown in the image below, I would be extremely grateful if someone could give me some advice

In the programming interface, it can be found under \"Program Elements\" → \"Libraries\" → \"Standard Library\" → \"TI-S7 Converting Blocks\". Note: Do not use FC105 and FC106, which are located under \"S5-S7 Converting Blocks\"; these functions are intended for S5 input/output templates and cannot be used with S7 input/output templates.

Thank you, boss. I was wondering why there was no output, and after changing the range, when I reopened the program, the range reverted to its default value again. 😳
