Not sure if you are aware but Kepware also has a data logging protocol that will log data directly to SQL so there is no need for a Scada system if it's only data your interested in, this is limited to enabling data to be logged on demand it would rely on other signals from PLC's for example only log when certain states exist.These cookies are essential in order to enable you to move around the website and use its features. Would it be Modbus RTU or ASCII as this could be a problem. To be honest I wouldn't bother with a data capture PLC all you would be doing is putting in another source of failure and getting all them PLC's talking on Modbus probably a bit of a challenge, Kepware informed me some years ago when I had concerns over vast amounts of data that we needed to cope with that they had a system with over a million tags and it was coping well. I'm also thinking of CC-link but couldn't come to conclusion. B'cos i couldn't find a source where Omron PLc can communicate Modbus tcp/ip or not. I am not sure how MODBUS TCP/IP gonna be more effective in this application. So i would purchase a Master PLC (not selected yet) and connect all the factory PLC to it and make the Master to communicate with Kepware.

I am just thinking of Modbus TCP/IP Slave/Master mode of communication. Now i have to get the MES data from all the PLC mentioned above.

I just want to play save and advance so that is the reason i am sticking with Ethernet Mode of communication rather other serial communication

We need to fetch all the required MES data from all the PLC and send it to the Server which has Kepware. We cant do much change in programming cos they dont want to affect their production. The pressing machine and the plc in it are all minimum 15years old.

Over there in Kepware Mitsubishi Fx Driver mentioned that FX2N PLC can be connected to Kepware by using Ethernet Encapsulation through FX2N-CNV-BD + FX2NC-ENET-ADP.
#Qj71c24n modbus rtu software
Speaking of the software they used is unknown. Not looked into whether there are registers in the 8000 range to force the baud rate on the programming port using plc code. I came across this when I used kepware connected via Ethernet encapsulation communications to 422 converter, once online with GX Developer at 115Kb kepserver would talk but if PLC power cycled would only connect at 9600. Many OEM's have used the E series of HMI's on Mitsubishi and indeed Mitsubishi at one time used a badged version of the Beijers HMI.Īlso note that if you use the 422 programming port on the Mitsubishi, kepware will only connect at 9,600 baud unless forced to higher baud rate by the Mitsubishi programming software but will revert after power down. Some HMI's have pass through mode so that a programmer or other comms can be used to connect to the plc. I believe that the CJ series also have Ethernet cards.

Both the FX ones have modules for Ethernet and kepware does talk to them however the FX2N is now redundant and no longer available you could upgrade to FX3U, the software can be converted in most cases but it depends what programming software was used if gx developer then no problem but if GXIEC then some of the libraries may cause issues if upgrading to GXWorks 2
