Interacting with the PLC
GFK-1918D CIMPLICITY Logic Developer - PLC Version 4.00 33
INTERACTING WITH THE PLC
Communicating with the PLC is necessary to perform such operations as storing
and loading programs or monitoring data values and PLC status information. You
can connect to a PLC from Logic Developer - PLC over a serial, Ethernet or modem
connection, depending on the capabilities of the PLC.
All interactions with a target are available from the target’s right-click menu.
Validating a Target
Validating your project detects any syntax errors that may be present. Error
messages are generated for each error and displayed in the Feedback Zone. A
project containing errors cannot be downloaded. For that reason, whenever you
initiate a download, the logic is automatically validated.
To validate a target
• In the Project tab of the Navigator, right-click a target and choose Validate.
Logic Developer - PLC checks all items under the target for syntax errors. Any
errors detected are noted with messages in the Build tab of the Feedback Zone.
Tip: Double-click an error message to locate the noted error in your project. The
appropriate editor or tool opens automatically with the item in question selected.
Tips showing you how to proceed are displayed in the Companion. To open the
Companion, press
SHIFT + F11.
Online/Offline
When offline from a target PLC, there is no ongoing communication between the
PLC and your development computer. When offline from the target PLC the
number and type of interactions available are limited, and the actual
communication link is not required as long as you only edit logic. If a
communication link has been configured and the Offline PLC Operations option is
enabled, you can:
■
Download to the PLC .
■
Upload from the PLC.
■
Start the PLC.
■
Stop the PLC.
■
Clear the PLC.
