2. What are the steps to write a meter program using PLC high-speed counter instructions
Based on PLC The programming of the meter counting program for high-speed counters is based on the acquisition of encoder pulses by the high-speed counter, combined with electronic gear ratios to convert meters, ultimately achieving accurate meter counting. 1. Prior hardware preparation and wiring require confirmation of the following hardware and completion of wiring: • PLC selection: Choose a PLC with a built-in high-speed counter channel, such as Siemens S7-1200/1500, Mitsubishi FX5U, Omron NX series, etc., prioritize confirming the maximum counting frequency of the high-speed counter, and match the encod
4. Initialize the counter: Write an initialization program to reset the current value of the high-speed counter to zero, which can be triggered by Z-phase or automatically reset by power on
3. Electronic gear ratio and meter conversion logic. This is the core link of meter accuracy: • Calculate the meter corresponding to a single pulse: Single pulse meter length=roller circumference/(encoder line number x quadruplex coefficient), where roller circumference=π x roller diameter. Real time meter calculation: The current meter length is equal to the current count value of the high-speed counter multiplied by the corresponding meter number of a single pulse. • Exception handling: Add count overflow protection, automatically reset the count when the count value exceeds the maximum storage value of the PLC
