- get serial cable 1747-CP3 or 1756-CP3 (or any null modem cable)
- connect one end to CPU and other to your PC
- open RSLinx, load DF1 driver, select ControlLogix and hit
Autoconfigure. You might want to change
COM port to match address of your computer COM port.
- Once you get sucess, you should be able to browse in RS Linx and
find the connected PLC. This is REQUIRED before you can go
online with the RSLogix.
- If you don't have offline copy of the PLC program you should be able
to go inlone and upload program from PLC (note you will have to
create new project - just blank file that matches CPU you want to
upload from)
Having no offline copy of the running SLC will make it hell
of a job to do any work with the program. If you have at least
I/O list of the machine or electrical diagrams, you might be able
to figure out most of the internal bits and troubleshoot the
program. Otherwise - good luck...
- Once you have uploaded program from the SLC, you can go to
controller properties and check the IP address (if static!).
- this should let you work with the PLC but as you guessed
DF1 is not nececarily the screamer. If you want to get faster
connection you can get a single etherenet crossover cable
OR use ethernet hub (or switch) and pair of ethernet straight
cables to make phisical connection.
- You have to use proper subnet mask and IP address on both PLC and
laptop in order to communicate (typically you leave PLC settings
as they are if this is part of working machine and just change
your laptop eth. configuration).
- Once you have done this, you do the same thing as before:
open RS Linx, instal eth. driver, MANUALLY enter the IP address
of the PLC, and make sure you can see the PLC while browsing
in RSLinx. Once this works you can use it in RSLogix...
