Timer Reference (Taaa): Specifies the timer number.
Preset Value
(Bbbb): Constant value (K) or V-memory.
Current Value : Timer current values are accessed by referencing the associated V or T memory
location*. For example, the timer current value for T3 resides in V-memory, V3.
Discrete Status Bit
: The discrete status bit is accessed by referencing the associated T memory
location. Operating as a “timer done bit,” it will be on if the current value is equal to or greater
than the preset value. For example, the discrete status bit for timer 2 would be T2.
NOTE: The accumulating timer uses two consecutive V-memory locations for the 8-digit value, therefore
two consecutive timer locations. For example, if TMRA T1 is used, the next available timer number is T3.
NOTE: A V-memory preset is required if the ladder program or an OIP must be used to change the
preset.

Accumulating Timer (TMRA)
The Accumulating Timer is a 0.1 second two input timer that
will time to a maximum of 9999999.9. The TMRA uses two
timer registers in V-memory.
Accumulating Fast Timer (TMRAF)
The Accumulating Fast Timer is a 0.01 second two-input
timer that will time to a maximum of 99999.99. The TMRA
uses two timer registers in V-memory.
Each timer uses two timer registers in V-memory. The preset
and current values are in double word BCD format, and the
decimal point is implied. These timers have two inputs, an
enable and a reset. The timer starts timing when the enable
is on and stops when the enable is off (without resetting the
count). The reset will reset the timer when on and allow the
timer to time when off.
NOTE: *May be non-volatile if MOV instruction is used.** With the HPP, both the Timer discrete status
bits and current value are accessed with the same data reference. DirectSOFT uses separate references,
such as “T2” for discrete status bit for Timer T2, and “TA2” for the current value of Timer T2.
