After the ladder logic changes the value of Local:1:O.Data[247] from 5 to 0, then

5.2.3 Special Function Blocks

Special function blocks are optional blocks used to request special tasks from the
module.
Initialize Output Data Blocks (1000 to 1049)
Use the Initialize Output Data parameter in the configuration to bring the module
to a known state after a restart operation. If the Initialize Output Data parameter
is enabled, when the module performs a restart operation, it will request blocks of
output data from the ReadData array in the processor to initialize the Read Data
area of the module's internal database.
