UniOPC sample rate

[Jimbob]

Hi

I am succesfully using uniopc server (now I have the baud rate the same on the plc and server )

But I can't seem to get the sample rate from the opc to plc any faster than 1 second. Is that as fast as it goes ?

Hi Jim,

What is the Baud Rate you have set on the PLC and in UniOPC Server?

The Sample Rate can depend on the way your PLC is connected, but if you are using a Standard RS232 Cable for communicating with the PLC you should get faster Sample Rates.

In UniOPC Server the Sample Rate setting should look like "00:00:00.00" if you set it to "00:00:00.01" then you should have a 100mSec Sample Rate.

Hope that helps!
