PPC380AE01 HIEE300885R0001 Controller Start Function block Direct or indirect command of the SFC. This command is activated as the parent step.
During the first scan of the SFC step, set the step.fs bit. In addition, the S: FS bit is set, which allows logic in any related operation to easily detect the state of the first scan. When a subroutine is called by multiple actions (actions that may be connected to other steps), it is accustomed to detecting the label added to a particular step by the first scan state without programming reference.

Many feature blocks contained must be used before blocks can be used. The block used to determine whether initialization should be done is by calculating the S:FS bit, which the function block identifies as the first scan after the pre-scan. Only if the SFC last scan activity step option is set to programmed reset or automatic reset. If the default value Do not Scan is set, no exception occurs. The purpose of the reset action (type R) is another action that was previously stored.

As described above when configuring, the reset action causes the logic to perform the final scan. The reset operation does not check to verify that the operation completed the final scan before it was stored. Result The target logic is scanned for the last time on each scan reset action.
