Block Programming Instructions
Precautions
Examples

The rest of the block program following timer will be executed if the Comple-
tion Flag for the timer is force set.
If the Completion Flag for the timer is force reset, only TIMW(813)/
TIMWX(816)) will be executed in the block program until the force reset status
is cleared.
The present value of timers programmed with timer numbers 0000 to 2047 will
be updated even when the timer is on standby. The present value of timers
programmed with timer numbers 2048 to 4095 will be held when the timer is
on standby.
The timer numbers are also used by the other timer instructions. Operation
will not be predictable if the same timer number is used for more than one
timer instruction. Use each timer number only once. The only way that the
same timer number can be used dependably is if only one of the timers is ever
operating at the same time. An error will occur in the program check if the
same timer number is used in more than one timer instruction.
An error will occur and the Error Flag will turn ON if an indirect IR designation
is used for N in BCD mode and the address is not for a timer present value or
if SV is not BCD.
The timer will not operate correctly if the cycle time is 100 ms or longer.
Note No block programming instructions will be executed after the input condition
for TIMW(813) turns ON until TIMW(813) times out. The other block program-
ming instructions will be executed again after the set time for TIMW(813) has
expired. If, however, online editing is executed for a task containing a block
program, the wait status created by TIMW(813) will be cleared and the block
program will be executed again from the beginning.
In the following example, "B" will be executed 20 seconds after "A" whenever
CIO 000000 is ON.
