Timing diagram (TMR000 #00010 and 0500 in the above example)

•

0500 and 0501 turn ON 1 second and 3.5 seconds respectively after 0000 turns
ON.

•

TMR000 is a subtraction timer. When the current value reaches "#00000",
contact T000 turns ON, and then output relay 0500 turns ON.

•

When input relay 0000 turns OFF, contact T000 and T001 turn OFF and the
current values of TMR000 and TMR001 are reset.

Note 1: The TMR number cannot be the same as any other TMS, TMH, TMR, C, or UDC
instructions in the same program.
Note 2: The current value of TMR is not retained but is reset to the preset value if a power
failure occurs or if power is turned OFF.

Tips

•

When the number specified by TMR is used as a contact (T000 in the above
example), this contact can be used as many times as desired. It can also be
used as both N.O. and N.C. contacts.

•

Timer accuracy = 0.1 sec. + (1 scan time) (max.)
