Function blocks are executed sequentially for each page.
Executed from the top down.
A loopback connection can be created by connecting the output terminal from
the function block that comes later in the execution order to the input terminal
to a function block that comes earlier in the execution order. A jump tag is
used to make the loopback connection.
System settings are performed only after programming has been completed.
It is normally not necessary to change the system settings. Make the settings
in the following cases.
The system settings are accessed from the Project Window.
■
Manually Setting the Cycle Time
The G9SP Configurator calculates and automatically sets the minimum cycle
time supported for operation according to the program contents and Safety
Input terminal settings. Therefore, the cycle time depends on the program
content and capacity, and recalculation of safety response performance is
required. This can be avoided by manually inputting the cycle time.
■
Prohibiting Using a Memory Cassette to Restore Memory
Change the system setting to use the prohibit restore setting described in 11-
3 Restoring Data to G9SP-series Controller.
The Jump tag is used to make loopback connections.
The Jump tag turns ON when FB [2] is executed, so Output 1
(the result of FB [1]) turns ON one cycle later.
The settable cycle time range.
The minimum cycle time for operation.
This time depends on the program contents.
