Select the [System Settings] tab to display the
[System Settings] workspace.
If the [System Settings] tab is not displayed
in the workspace, on the [View (V)] menu, point to [Workspace (W)],
and then click [System Settings (S)].
From [Display], select [Display Unit].
Select the [Logic] tab, and then select either
[RUN] or [STOP] under [Logic Program Operation] of the [Run at
Start Up] section under [Logic].
Select [Synchronous] in [External Equipment
Operations] to synchronize communication with external devices when
the power is ON.
Communication synchronization with external
devices when powering up
External equipment operations when the power is ON are handled
as follows.
When [External Equipment Operations] is set to
[Synchronous], check whether communication synchronization is
established.
When synchronization is selected, for [Logic
Program Operation] select either the [RUN] or [STOP] option.
When synchronization is not selected, the logic
program checks for synchronous communication to start. Logic will
not start until synchronization is set.
When the [External Equipment Operations] is
[Asynchronous], the logic program does not check whether
communication synchronization has been set.
*Communication synchronization is checked
only when the power is ON and the controller is reset.
While the power is ON, when [External Equipment Operations] is set
to [Synchronous], it checks whether communication synchronization
is established even when [Logic Program Operation] is set to
[STOP].
*Synchronize only external addresses (external devices) used in the
logic programs.
