Name
Error Flag ER
An error will occur and the Error Flag will turn ON if BPPS(811) or BPRS(812)
is not in a block program or if N is not between #0000 and #007F (binary).
BPPS(811) can be used to pause the block program that contains it. When
the block program is then restarted using BPRS(812) from another block pro-
gram, the paused block program will restart from the next instruction after
BPPS(811).
If a paused block program contains TIMW(813), TIMWX(816), TMHW(815), or
TMHWX(817), the PV of the time will continue to elapse even while the block
program is paused.
The following diagram shows a basic example of pausing a block program.

Note If the block program that is being paused appears after BPPS(811), it will not
be executed. If the block program appears before BPPS(811), it will be
paused starting the next cycle.
If CIO 000000 is ON, the following program pauses execution of either block
program 1 or block program 2 depending on the status of CIO 000001. The
block program that was paused is then restarted after 10 seconds.
