FX5U to Omron NX102-9000

[J2870]

Rather new to Mitsubishi and networking in general, but I am trying to move a scanned part number from the FX5U data register D1000-1016 to an Omron NX102-9000.  I really have no idea where to start in GX Works 3 to identify and send the data.

Have a look at simple plc communication. Does the omron plc fall under CP/CJ series?  

Or does it support modbus TCP/IP ?

I am trying simple plc comm to no avail, but I don't think it is the same as CJ/CP.  I am not sure how to tell if it supports modbus TCP/IP.

I believe there are Modbus TCP function blocks for the NX102.  They may be built in or it may be a library that can be downloaded, I don't recall which.  I don't have the software on this computer to double check, but will try later this evening.

NJ and NX Series are not CP/CJ Series.

There are instructions in the NX102-9000 called ModbusTCPRead and ModbusTCPWrite that may be able to help you with this.

You may also be able to do this with Socket communications, though I have not personally done either of these.

So in the interest of communicating solutions, I did end up using the "Simple PLC Communication Setting" under FX5CPU->Ethernet Module on GX-Works 3.  I had already tried it, but I what I was missing is that on the Omron NX102-9000 side you can only use Port 2 for data transfer.  I did this already, but just to note, make sure you enable the specific memory check box you are writing to on the Omron side under Sysmac studio.
