 ===== 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. Read the elapsed time updated by ''Iton(0, …)'' with ''IgetTime(0)'' and print it every 0.5 s. The reading is 0 when input is OFF.

 ===== 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()''.
+  * Call the timer with the same ID first. An ID that has not been created returns 0.
-  * 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.
+===== Built-in Commands in the Same Category =====
-  * Configure only one ''Itimer'' callback per hardware timer.
-  * Defining an ISR for the same timer directly in the sketch may conflict with ''Itimer'' operation.
+  * [[:en-us_commands:reference:igetstate|IgetState() View detailed description]]
-  * ''ItimerStopAll()'' stops only hardware interrupt timers. It does not reset PLC-style timer states such as ''Iton'', ''Itof'' or ''Itmr''.
