How to access DL 450 memory on a PC

[blckpnthr 0]

I need to read the memory of a DL 450 to see the info contained within. Since it doesnt seem to support any form of Modbus I have no idea how to go about doing this. Any ideas?

With the exception of the modular plug (Port 2) all the ports support Modbus. Then there is always Directsoft itself.The manual for the 4xx CPUs is available here. Edited 4 Sep 2010 by b_carlton

Thanks for clearing that up. I have a utility that lets me access Modbus holding registers and I know how to use that. How would I use DirectSoft to access the registers of the DL PLC. Thanks

Directsoft is the programming package for these PLCs. It can be used while online to see the contents of the data areas.
