Modbus TCP Communication with multiple masters


#1

Hello Everyone

      Here i am using the OPTO S1 controller as a modbus TCP slave with Siemens Wincc and Honneywell DCS systems are the masters 
         [B] (i.e 1 Slave(OPTO) + 2 Masters(WINCC + HONNEYWELL) at a time)[/B]

----->while exchanging the data(holding registers) between OPTO and Wincc was good,communication re establishment was also good
----->while coming to the Honneywell system it is taking more than 10 seconds to read and write operations,as well as its taking more than 30 minutes time to establish the communication with honneywell,

               Please suggest me to solve the communication issue with honneywell.
