CPU old version with CP recently version
Posted: Thu Aug 09, 2012 5:46 pm
Hi everyone! Look, I need to communicate a S7400 PLC with a Schneider Panel (Magelis) with Ethernet protocol, however PLC coupler ( 6ES7-443-IEX11-0XE0 ) its useless so the dilema is the following:
That CP can't be purchased because it's obsolete already, so its substitute is CP 6ES7-443-IEX20-0XB0.
S7400 CPU is 6ES7-414-3XM05-0AB0 (an old version), so I don't know if will be a problem during download procedure because CPU is older and CP is newer.
Will be firmware error or similar during/after download?
The other way I have is to purchase a gateway (LUFP, from Schneider) ProfibusDP/ModbusTCP to communicate Magelis Panel with S7400, but I don't know anything about ModbusTCP (sincerly, I would like to have some examples or something)
All suggestions are welcome
Regards in advance
