Downloading and Uploading the Elements of Your Project
Your project consists of different elements:
Program block
-
Data block (optional)
-
System block (optional)
-
Recipes (optional)
-
Data log configurations (optional)
-
When you download a project, the program block, data block and system block are stored in
permanent memory for safekeeping. Recipes and data log configurations are stored in the
memory cartridge, and replace any existing recipes and data logs. Any program elements not
included in the download operation are left unchanged in permanent memory and the memory
cartridge.
If a project download includes recipes or
data log configurations, the memory
cartridge must remain installed for proper
program operation.
To download your project to an S7-200
CPU:
1. Select the File > Download menu
command.
2. Click each project element you
wish to download.
3. Click the Download Button.
When you upload a project to your computer using STEP 7--Micro/WIN, the S7-200 uploads the
program block, data block and system block from permanent memory. The recipes and data log
configurations are uploaded from the memory cartridge. The data from the data logs is not
uploaded to your computer using STEP7--Micro/WIN. The S7-200 Explorer is used to upload the
data from the data logs (see Chapter 14).
To upload your project from an S7-200
CPU:
1. Select the File > Upload menu
command.
2. Click each project element that you
wish to upload.
3. Click the Upload Button.
