Hello everyone!
Will you please suggest what interface should I use for Scheider Electric v.3.3.2.3? It is a Power Logic System Manager Software developed by Square D/ Scheider Electronics. Also for Oxford XpertEase it is a software that controls the MDX1000.
Thanks guys! This would be of great help.
Regards,
Denman

By the way, Schneider Electric Power Logic Communications are
--Ethernet port
--Infrared port
--RS485 port
--Modbus protocol

Hi Denman, welcome to the forum! The clue is in your last post, Modbus/TCP protocol. There is a modbus OPC server, so once you have it in OPC you can connect it to a data historian with the historians OPC server (assuming they provide one). In the case of PI they do so you can connect. {Power Logic Device} --> *Modbus/TCP* --> {Modbus OPC} --> {PI OPC} --> PI Data Historian. Hope this helps.

Thanks a lot!
How about for MDX1000? It is developed by Oxford Instruments. It has a software called "xpertease". It also has an external RS232 port.

Hi Denman,
My preference would be Modbus/TCP and aim to get the data in via OPC. This can be done using an Modbus OPC Server and the PI OPC Client. Try the vendor for the OPC server or failing this contact one of the independant OPC server suppliers such as Kepware, Matrikon or Software Toolbox.
Having said this however, there are a number of PI Interface available for talking native Modbus protocols, so you also have that option.
For the Oxford route and assuming there isn't a driver to talk OPC or some other protocol then it's a different situation. PI will need to be able to convert the data being sent via RS-232 (assuming we're talking protocol and not electrical comms standard). I believe there are PI Interfaces that can do this (Message Logger?) but this would have to be purchased and configured in line with your instrumentation. However the key to this solution would be understanding what was being transmitted by via the Oxford instrument so that the PI Interface can be correctly configured to interpret the data in a format it understands.
My experience with lab instrument systems designed to be sold as black boxes is that it almost always calls for a bespoke solution, if this is the case here then you may need to talk to Oxford for details on what they send over the RS232 port for the instrument in question.
