Communication Delay Between Omni-6000 Flow Computer and IC95CMM004


Thread Starter


We are having a Omni flow computer (FC), Model No-6000. Datas from fields are coming to FC then though RS485 MODBUS communication it is transmitting data to IC95CMM004 module of GE RX3i(CRU320). But the data updatation rate is very slow. Every times it takes almost 5 to 10 minutes to update a data. There are approx 20 byte data. Scan rate in FC is set as zero and in IC95CMM004 set as 500 ms, Baud rate-9600.

Please suggest the corrective measures.
