UP/DOWN
Note Observe the following precaution when using UP(521) and DOWN(522) in a subroutine.
• The operation of UP(521) and DOWN(522) will not be consistent if the same subroutine is executed
more than once in the same cycle.
• An subroutine will not be executed while the input condition for the subroutine is OFF. Caution is thus
required when using UP(521) and DOWN(522) in a function block definition. For details, refer to
information on SBS(091).
