automation ladder diagram basic knowledge

Build a simple ladder diagram.
Enter the following simple rung in the Ladder Diagram editor by selecting each ladder component from the tool bar and placing it in the Editor window. To enter the contact variable, select the normal pointer (press escape), double click above the contact, and choose T_100MS from the list box. To enter the coil reference address, double click the coil and type 1q. T_100MS %Q00001

Edit a variable name.
In the Variable Declaration Table, type in a name and description for %Q00001. The name may be up to 32characters in length, and the description may contain up to 64 characters. The workspace on your desktop should now be similar to the one pictured on page 5. VersaPro PLC Programming Software Familiarization Lab October 2000

Importing Files
One of the first tasks you might undertake is to import a program developed using one of GE Fanuc’s earlier PLC programmer products, Logicmaster or Control. (VersaPro also provides the ability to import variables created in other applications such as CIMPLICITY HMI, Logicmaster, Control, or tools like Excel or Access.) To accomplish the tasks in this lesson, you will need syntactically correct Control and Logicmaster folders and Excel. The tasks are independent of each other – if you skip one, you will still be able to do the others.

Import a Logicmaster folder.
Series 90-70, Series 90-30, and Series 90 Micro folders can be imported from Logicmaster.
1. Select File, New Folder.
2. You will be prompted to close and save your existing open folder. (Only one folder can be open at a time.) Click Yes.
3. The New Folder Wizard will appear. Type a name of your choice for the folder. If you want to put the new folder in a directory different from that specified in the Location field, click the browse button next to the Location field to select the folder path.
4. Click the Next button.
5. On the next screen, choose Import Logicmaster 90. In the From field, use the browse button to locate a Logicmaster folder.
6. Click Finish. The New Folder Wizard closes, and VersaPro attempts to complete the import process. Details of the import process are logged in the Information Window.
7. Spend a few minutes reviewing this folder. Note that all nicknames are imported and that all comments retain their original format. See how different instructions look in the VersaPro ladder diagram editor. You can use the function toolbar to create new logic. VersaPro PLC Programming Software Familiarization Lab October 2000

Import a Control software folder.
You can import VersaMax (.F2K), Series 90-30 (.F3X), and Series 90-70 (.EF7) folders from Control.
Note: When importing a Control folder, variables must first be exported from the Control folder in shared name file (SNF) format, if you want to import the variables.
1. Create an SNF File.
a. If you do not already have an .snf file containing variable information, open a folder in Control
software and use the Export feature from the Variable Declaration Table to create an .snf file.
b. Close Control before you proceed.
2. Create a new folder in VersaPro.
a. Select File, New Folder.
b. You will be prompted to close your existing open folder. (Only one folder can be open at a time.)
c. The New Folder Wizard will appear. Create a new folder with a new name. If you want to put the new folder in a directory different from that specified in the Location field, click the browse
button next to the Location field to select the folder path.
d. Click the Next button.
e. Choose Import Control on the next screen. In the From field, use the browser button to locate a Control folder.
f. Select the Include SNF checkbox, then click the Browse button and, in the Browse dialog box that appears, locate the SNF file that is associated with the Control file to be imported. (This field is optional.)
g. Click OK to begin the Import process.
h. Spend a few minutes reviewing this folder. Note that all nicknames are imported. Also, note that Comment contents are not imported. See how different instructions look in the VersaPro ladder diagram editor. You can use the function toolbar to create new logic.
3. Import a Shared Name File.
a. In the folder you just created, select any cell in the Variable Declaration Table. Select Tools,
Import Variables.
b. Locate the Shared Name File (filename extension .snf) on your computer. A browser window will open.
c. Click Open to import the file. If the file being imported contains variables that conflict (same
name and scope) with those in the VersaPro folder, the Variable Resolution dialog box will
appear. If this happens, you can simply click OK to accept the default settings, or press F1 to get
more information about the Variable Resolution settings.
d. The results of the Import process will be logged in the Information Window. Verify that the
variables you imported appear in the Variable Declaration Table.
