Control Flow Normal - Omron FH-3 Series Reference Manual

Control Flow Normal

This function is used to put the currently executed measurement flow in the wait state to allow execution of a
specific communication command from an external device.
Used in the Following Case
• To execute a communication command during measurement flow processing
Example: Branches into multiple defect processing items based on the measurement result of the 2D code.
Control flow normal causes the measurement flow to wait and acquires the measurement result of the 2D code.
Based on the acquired result, the conditional branch destination changes.
Defect
This processing item is compatible with measurement flow control using the communication modules below.
Parallel
NA NA
In the wait state, the communication commands below can be executed. For details on the communication
commands, refer to Reference:
"Vision System FH/FZ5 Series User's Manual for Communications Settings (Cat. No. Z342)."
Command name
Get Unit Data Gets the parameters and measurement values of the processing unit.
Set Unit Data Sets the parameters and measurement values of the processing unit.
Return to Start of Flow Branches to the start of the measurement flow (processing unit 0)
To clear the wait state, use the Set Unit Data command. The wait state can be cleared by setting the "Wait state
clear command" to "1" in the External Reference Table.
