  1. QJ71E71-100 MODBUS TCP

    Hi, This is Kaviraj. I am using Q06udv cpu + 3 ethernet cards ( 1 eth card for kepware connect , other two cards for modbus tcp connecting 16 GOC43 devices through predefine protocol). I am getting the data to PLC but facing below issue.  Problem-01 (major) in 2nd and 3rd card i am facing X19 (Initial normal completion signal) bit OFF after some time randomly like 1 or 2 hours later. Problem-02 Connection ports are closing regularly like  1.5 sec to 2sec after port open status. so i am managing by executing port open instruction instantly after 200ms of port close status. Need help, pls support.
