Chapter 7 Create Logic in the New Ladder Editor
Use the Logic Enable Off option to notify the device to stop executing
the logic diagram. When you select this option, the device enters an
idle state, turning off the Logic Enable Bit in the produced data. The
Logic Enable Bit in the Produced I/O assembly of the device reflects a
0 or 1 for Logic Enable Off or Logic Enable On. To set Logic Enable
Off, choose Communications > Logic Enable Off.
For some host software, the logic enable is determined by the
connection. For more information, refer to Chapter 6, Navigate the
New Ladder Editor Interface.
Verify Logic
Once you have created your logic, you must verify your configuration
before downloading it to the firmware in the device. Click Verify in
the toolbar, or choose Tools > Logic Verify to verify the logic syntax.
• Each rung has minimum input and output instruction.
• Each branch has minimum instruction.
• Each instruction has the minimum number of pins bound.
• Each parameter has the appropriate data type associated with it.
• Both ends of a binding are of the same type.
• Device has enough memory to store the logic and screen format
data.
If any of the logic syntax fails, the Message Pane displays
corresponding error messages. You cannot download the logic to the
device until the logic passes the verification without error.
If the logic syntax and the screen format data pass the verification
without error, the Message Pane displays the actual memory usage for
logic and screen format.
If the logic syntax passes verification, and if both the logic layout and
Tag Database can be downloaded to the device, but the other screen
format data cannot be downloaded to the device, the Message Pane
displays corresponding error information. If you want to change
which items to include in the download,
choose Tools > Screen Format.
