No it is not working I have seen a post that says if we remove the CPU battery and power it down for a day then it will go it is factory state even tried this method but no Luck 

just asking is there any firmware update or procedure do a full factory reset for this CPU 

I dont have spare CPU better go for service I think 

How about an ethernet card, do you have a spare QJ71E71-100 laying around? 

[madhan]

I dont have a ethernet card thinking of buying a used one meanwhile i would like to communicate my weintek HMI to this model CPU using Modbus QJ71MB91 can someone Provide me the process to communicate 

 

Thank you

I have not used that HMI brand before, but Modbus setup on the MB91 is pretty easy. 
It will show up as an intelligent function module and have several setting windows. 

 

Switch settings is for IP setup and pointing device assignment to the user settings
Modbus device assignment tab will be how you set up blocks of addresses to be shared by the HMI and PLC 

[madhan]

no this model is a serial communication model and the switch settings for plc and HMI are same, used rs485 cable connection  and I dont know why I need to set device assignment for HMI. Is there any specific  procedure for HMI and PLC (any HMI not only this ) through modbus communicaiton ?
