 ===== Example =====
+This example selects MPINO-8A4R(T)-S and uses input ''P0'' and output ''P32''. Call the command on every pass through ''loop()'' without blocking it. ON time at ''P0'' accumulates. ''P32'' turns on after 3 s; OFF time does not clear the sum. ''P1'' resets it.
 <code cpp>
-const uint8_t START_INPUT = 0;
+const uint8_t RUN_INPUT = 0;
 const uint8_t RESET_INPUT = 1;
-const uint8_t RUN_OUTPUT = 32;
+const uint8_t OUTPUT_PIN = 32;
-void setup() {
+void setup() {}
-  Serial.begin(115200);
-}
 void loop() {
-  const bool start = IdigitalRead(START_INPUT, 5);  // Read the input repeatedly and update only if all samples match. If HIGH and LOW are mixed, retain the previous stable state.
+  const bool run = digitalRead(RUN_INPUT) == HIGH;
-  const bool reset = IdigitalRead(RESET_INPUT, 5);  // Read the input repeatedly and update only if all samples match. If HIGH and LOW are mixed, retain the previous stable state.
+  const bool reset = digitalRead(RESET_INPUT) == HIGH;
-  const bool ready = Iton(0, start, 1000);  // (On Delay Timer) Return true only after the condition remains ON for the set time.
+  const bool elapsed = Itmr(0, run, 3000, reset);  // Accumulate ON time; clear it when reset is true.
-  const bool stopDelay = Itof(1, ready, 500);  // (Off Delay Timer) Return false after a set delay following the condition turning OFF.
+  digitalWrite(OUTPUT_PIN, elapsed ? HIGH : LOW);
-  const bool startPulse = Itpl(2, ready, 200);  // (Pulse Timer) Return true for the set duration from the instant the condition turns ON.
-  const bool inspectionWindow = Itmon(3, startPulse, 3000);  // (Monostable Timer) Output a pulse whose duration is not extended by another trigger while running.
-  const bool batchDone = Itmr(4, ready, 10000, reset);  // (Retentive Timer) Accumulate the time the condition is ON; clear it with the Reset input.
-  const unsigned long elapsed = IgetTime(4);  // Return the specified timer's current elapsed time.

 ===== Precautions =====
-  * Timer interrupt callbacks run inside an ISR. For safety, change only flags in the callback and perform actual control processing in ''loop()''.
+  * Call the timer command repeatedly in ''loop()'' so elapsed time and OFF input are processed.
-  * Do not use slow or interrupt-dependent code such as ''delay()'', ''Serial'', I2C or SPI in callbacks.
+  * Do not share a ''timer_id'' between different timer operations; use a separate ID for each.
-  * Normally, call ''ImodbusRTU()'' repeatedly in ''loop()''. Call it from a timer interrupt with a sufficient interval only when long ''delay()'' calls or debug output slow down ''loop()''.
+  * When ''reset'' is true, the accumulated time and done state are cleared.
-  * Do not use the default ''ItimerSet()'' together with ''tone()'' using Timer2 or ''analogWrite()'' on Timer2 PWM pins.
-  * Explicitly using Timer1, Timer3, Timer4 or Timer5 may conflict with PWM, analog output or high-speed counter functions using that timer.
-  * Configure only one ''Itimer'' callback per hardware timer.
-  * Defining an ISR for the same timer directly in the sketch may conflict with ''Itimer'' operation.
-  * ''ItimerStopAll()'' stops only hardware interrupt timers. It does not reset PLC-style timer states such as ''Iton'', ''Itof'' or ''Itmr''.
