BEND<001>
BPRG(250) is used to switch to block programming and BEND<001> is used
to switch back to ladder-diagram programming. For every BPRG(250) there
must be a corresponding BEND<001>. The corresponding block program will
be executed with the execution condition for BPRG(250) is ON and it will be
skipped (not executed) when the execution condition is OFF.
Precautions
The same block number cannot be used more than once.
