Downloading and Entering a Program
• Goal: To transfer a program to the PLC and run it.
At the top of the window select “Comms” then “Download”. You will be asked for a filename, enter ‘seminar’ for now. Later on you should give this a name related to the project.
You will be asked if you are sure you want to download, select “yes”. You may get a message that the SLC is in “RUN MODE”. If you select “Yes” the program in the PLC will stop running so that the new program can be downloaded. After the program is downloaded you will be asked if you want to switch back to “RUN” mode, select “Yes”.
When asked “Do you want to go Online?” select “Yes”. The screen will now show the actual state of PLC inputs and outputs. Turn on Input 0 to the PLC, and notice that the rung on the screen changes. It is also worth noticing that there is a slight delay between pushing the switch, and the change on the screen.
NOTE: After this point, keystrokes and menu choices will not be fully described.
