Input Area
Area you can use for inputs is divided into 28 x 16-bit
areas.
The Input Area field displays the input area number and
associated bits in brackets "input area number (start bit - end
bit)". You cannot edit the Input Area.
Input Type
Select the input type from either [Bit] or [Word].
Output Area
Area you can use for outputs is divided into 28 x 16-bit
areas.
The Output Area field displays the output area number and
associated bits in brackets "output area number (start bit - end
bit)". You cannot edit the Output Area.
Output Type
Select the output type from either [Bit] or [Word].
Retentive output when controller ends
Select whether or not you want to retain output values when the
logic program stops. Select the check box to retain outputs.
-
The following operations will reset
outputs.
-

-
Restart the display unit.
-
Go to offline mode.
-
Run project transfer with [Transfer Project]
set to [Automatic] or [Retain retentive variables].
Required scan time
Displays the scan time with the current settings and I/O points
as : XX milliseconds (Input/Output: YY Points/ZZ Points).

When the send/receive values between the first
and second cycles match, the I/O status is updated. When the data
values had changed in the second cycle, the I/O status is not
updated.
