Function

•The progress value is updated when the startup condition is on, and the coil turns on when the progress value is greater than or equal to the set value.

•If the startup condition is turned off, the progress value is cleared and the coil turns off.

•The progress value is set in TC n and does not exceed 65535 (decimal).

•If the progress value is updated during RUN, the operation will be performed using the new progress value at that point.

•If an I/O is set for the set value, the set value can be changed during operation by changing the I/O value, since the set values are updated during each scan.

Notes

•The .01s time base can only be used for timer numbers 0 to 63 (64 points).

•The .1 s and 1 s time bases can be used for all timer numbers (0 to 255).

•A maximum of 256 points can be used for the timers TD, SS, CU, CTU and CTD in total.

However, the same area as the counter is used. The timer numbers and counter numbers may not be overlapped.
