Pipes in OPC Mirror

Hi Everyone¡

Firt of all i want to apologiza for my english.

Mi question is about the pipes in the OPC Mirror, I have a historic server in which i have installed OPC Mirror, this station is connected to an RTU which is connected to a flow computer, it is supose that my DeltaV station will receive the data from the flow computer by the RTU with OPC protocol, my problem is in the pipe, when the values in the flow computer change, the data is not refreshed automatically in my modules in the DeltaV station i have a delay around one minute to change to the new value, i use the opc watchit to validate the tag OPC and the value is the correct but not in the pipe, i tried in the pipes options but i can´t solve this i don't know what could it be the cause that makes the pipe not be updating the correct values.

I hope somebody else could help me with his experience.

Thanks.
