Outline of operation
● This instruction activates the waiting PBn when the execution condition of STARTPG PBn
turns ON.
● This instruction makes the active PBn be in waiting state when the execution condition of
STOPPG PBn turns ON.
● When switching PROG to RUN, operates in the default mode (start or wait). The start mode
of PB is specified using the menu of tool software FPWIN GR7 for Creating new program
block (PB) or Changing PB attribute. The default is start.
● At the time of rewriting during RUN, holds the PB start mode and does not reset it to the
default setting.
● A PB that is in the waiting state after startup clears the output in a single scan with the
program block active relay OFF in order to change the state of each input and output relay to
the state as shown below.
