In t seconds (t = SV × time base) after the input is On, the output is On.
If the input is Off, the output is Off.
Valid channel numbers: Ch 0 through Ch 255 (256 channels)
Done contact: TC + channel number
SV set range: 0 to 65,535
For t seconds (t = SV
× time base) after input is On, the output is On. At
the end of t seconds, the output is Off.
If the input is Off, the output is Off.
Valid channel numbers: Ch 0 through Ch 255 (256 channels)
Done contact: TC + channel number
Description
1. Ch 0 to Ch 15: Time base = 0.01 sec (10 msec)
Ch 16 to Ch 255: Time base = 0.1 sec (100 msec)
2. The output done contact of the timer is TC + channel number.
3. The channel number can only be used once. It cannot be reused by other timer or counter
instructions (UC, DC , UDC).
4. To change the Set Value or Present Value of the timer while the program is running, modify
registers W2048 to W2559. In GPC, you may also reference these registers using the PV or
SV designation.
5. The Present Value (PV) is reset to zero when the input is Off, in Stop mode, or when power is
off.
