TIMER_1_FB_M
• When the execution condition of (s1) turns on, counting the current value starts. The timer starts counting from "(s3)

1
ms". When it counts up to "(s2)

1 ms", (d2) turns on. The current measurement value is output into (d1).
• When the execution condition of (s1) turns off, the current value is reset to (s3) and (d2) turns off.
• A value in the range of 0 to 32767 can be specified for (s2).
• A value in the range of -32768 to 32767 can be specified for (s3). However, when a negative value is specified, the initial
value is set to 0.
