TIMER_CONT_FB_M
• This is a retentive timer that counts the time when the variable is on. When the execution condition of (s1) turns on,
counting the current value starts. There are two retentive timers: low-speed (TIMER_CONT_FB_M) and highspeed
(TIMER_CONTHS_FB_M) retentive timers.
• The timer starts counting from "(s3)
100 ms"( or 1ms if the high-speed retentive timer is used). When it counts up to "(s2)
100 ms"( or 1ms if the high-speed retentive timer is used), (d2) turns on. The current measurement value is output into
(d1).
• The on/off status of (d1) and (d2) is maintained even if the execution condition of (s1) turns off. When the execution
condition of (s1) turns on, the timer resume counting from the measurement it holds.
• 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.
• To reset (d1) of the retentive timer, reset (s1) of FB directly.
