Timer Area

In this example, a TR bit is used when two outputs have been directly con-

nected to a branch point.

In this example, a TR bit is used when an output is connected to a branch

point without a separate execution condition.

Note A TR bit is not required when there are no execution conditions after the

branch point or there is an execution condition only in the last line of the

instruction block.

The 4,096 timer numbers (T0000 to T4095) are shared by the HUNDRED-MS

TIMER (TIM/TIMX(550)), TEN-MS TIMER (TIMH(015)/TIMHX(551)), ONE-

MS TIMER (TMHH(540)/TMHHX(552)), TENTH-MS TIMER (TIMU(541)/

TIMUX(556)) (see note), HUNDREDTH-MS TIMER (TMUH(544)/

TMUHX(557)) (see note), ACCUMULATIVE TIMER (TTIM(087)/TTIMX(555)),

TIMER WAIT (TIMW(813)/TIMWX(816)), and HIGH-SPEED TIMER WAIT

(TMHW(815)/TMHWX(817)) instructions. Timer Completion Flags and

present values (PVs) for these instructions are accessed with the timer num-

bers. (The TIML(542), TIMLX(553), MTIM(543), and MTIMX(554) instructions

do not use timer numbers.)

Note CJ1-H-R CPU Units only.

When a timer number is used in an operand that requires bit data, the timer

number accesses the Completion Flag of the timer. When a timer number is

used in an operand that requires word data, the timer number accesses the
