Part III FP Instructions
TM_1s
Timer for 1s intervals (0 to 32767s)
Instead of using this FP instruction, we recommend using the related IEC instruction TM_1s_FB
(see page 922).
Please refer also to Advantages of the IEC instructio
ns in the online help.
The area used for the instruction are:
 Preset (Set) value area: SV
 Count (Elapsed) value area: EV
When the mode is set to RUN mode, the Preset (Set) value is transferred to the SV. If the trigger of
the timer instruction start is in the ON-state, the Preset (Set) value is transferred to the EV from the
SV.
During the timing operation, the time is subtracted from the EV.
The scan time is also subtracted from the EV in the next scan.
The timer contact T turns ON, when the EV becomes 0.
Calculation of the timing operation:
timing operation = time set value - 0 to 1/4 of units (250ms) + scan time
Example:
150s time set value and 8ms PLC scan time
Upper limit = 150000 - 0 + 8 = 150008ms
Lower limit = 150000 -250 +8 = 149758ms
The result is a timing operation from 149758ms to 158ms.
