 ===== 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. The output turns on after 1 s of continuous input and turns off immediately when the input goes off.
 <code cpp>
-void loop() {
+const uint8_t INPUT_PIN = 0;
-  bool run = digitalRead(0);
+const uint8_t OUTPUT_PIN = 32;
-  if (Iton(40, run, 1000)) {
+void setup() {}
-    digitalWrite(13, HIGH);
-  } else {
+void loop() {
-    digitalWrite(13, LOW);
+  const bool inputOn = digitalRead(INPUT_PIN) == HIGH;
-  }
+  const bool outputOn = Iton(0, inputOn, 1000);  // Return true only after the input stays ON for 1 s.
+  digitalWrite(OUTPUT_PIN, outputOn ? HIGH : LOW);
 }

 ===== 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()''.
-  * Do not use the default ''ItimerSet()'' together with ''tone()'' using Timer2 or ''analogWrite()'' on Timer2 PWM pins.
+===== Built-in Commands in the Same Category =====
-  * 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.
+  * [[:en-us_commands:reference:itof|Itof() View detailed description]]
-  * Defining an ISR for the same timer directly in the sketch may conflict with ''Itimer'' operation.
+  * [[:en-us_commands:reference:itpl|Itpl() View detailed description]]
-  * ''ItimerStopAll()'' stops only hardware interrupt timers. It does not reset PLC-style timer states such as ''Iton'', ''Itof'' or ''Itmr''.
+  * [[:en-us_commands:reference:itmon|Itmon() View detailed description]]
+  * [[:en-us_commands:reference:itmr|Itmr() View detailed description]]
