Accumulating Timer (TMRA)

1
The Accumulating Timer is a 0.1 second two-input timer that will
230
time to a maximum of 9999999.9. The TMRA uses two timer
240
registers in V-memory.
2
250-1
Accumulating Fast Timer (TMRAF)
260
3 The Accumulating Fast Timer is a 0.01 second two-input timer
that will time to a maximum of 999999.99. The TMRAF uses two
timer registers in V-memory.
4
230
These timers have two inputs, an enable and a reset. The timer will
240
start timing when the enable is on and stop timing when the enable
5
is off without resetting the value to 0. The reset will reset the timer
250-1
when on and allow the timer to time when off.

Instruction Specifications
DS Used
Timer Reference (Taaa): Specifies the timer number.
HPP Used
7
Preset Value (Bbbb): Constant value (K) or two consecutive V-memory locations. (Pointer (P)
for DL240, DL250-1 and DL260).
8
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 location V3.
9
Discrete Status Bit: The discrete status bit is accessed by referencing the associated T memory
location. 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.
10
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.
11
NOTE: A V-memory preset is required only if the ladder program or an OIT must be used to change the
12
preset.

NOTE: * Both the Timer discrete status bits and the current value are accessed with the same data
reference with the HPP. DirectSOFT uses separate references, such as "T2" for discrete status bit for Timer
T2, and "TA2" for the current value of Timer T2.
