12–2 Uploading and Downloading with A-B Processors
Publication 1770Ć6.5.16 - October 1996
To make sure the program image is stable during an upload,
the PLC interface prohibits program changes during an upload.
When you are using the following procedures, the interface blocks
all access to PLC memory.
To upload information from See page
PLCĆ2 processors 12-2
PLCĆ3 processors 12-2
PLCĆ5 processors 12-3
SLC 500 processors 12-6
Uploading from a PLCĆ2 Processor
If you have Then
PLCĆ2/05, Ć2/15, Ć2/16, Ć2/17, or Ć2/30
processor
Make sure the mode selector switch is in
the RUN/PROG or PROG position.
Go to step 2.
PLCĆ2/20 or MiniĆPLCĆ2 processor
The mode selector switch can be in any
position. Go to step 2.
2. To inhibit programming terminal access, enable the PLC-2
processor to receive mode-setting or physical reads using enter
upload mode. (For more on enter upload mode, see page
7–10 .)
3. Upload the information, using one or more physical reads.
(For more on physical read, see page
7–13 .)
4. To exit the upload mode, use exit download/upload mode.
(For more on exit download/upload mode, see page
7–10 .)
Uploading from a PLCĆ3 Processor
1. Determine the last memory address used using diagnostic status.
(For more on diagnostic status, see page
7–6 .)
2. Request the right to upload from the PLC-3 processor using
upload request. (For more on upload request, see page
7–34 .)
3. Shut down the PLC-3 processor using shutdown request.
(For more on shutdown, see page
7–28 .)
4. Upload information using one or more physical reads.
(For more on physical read, see page
7–13 .)
5. Exit the upload mode using restart request. (For more on restart
request, see page
7–23 .)
