90-70 system with pcm711 is communicating with daniel flowcomputer s600 but data is updating very slowly,,,any body got idea on this?

Maybe.
What do you call very slowly?
How much faster do you want to be?
How much data?
What protocol?

hello russ

in plc logic one sec timer is used to retrieve flow meter data but some times one sec delay is occuring and in scada is also another delay ,,,,but in flow meter data is continously updating,,,,how to improve this???/

am usiing rs485 modbus protocol, and 34 length registers are reading,

pcm is configured as basic

With the PCM711 and Modbus you should be able to get 34 registers very fast, maybe 4-5 times per second at 19.2 k baud.
Did you write the Modbus in the PCM or is this purchased from a third party?
Did this work better in the past or are you developing this now?
How does the SCADA fit in this, what/who is the SCADA. Does it communicate Modbus to the same devices? Who is the Modbus Master and who are the slaves?
