Error 33172 occurred at Read & Write data transfer between two or more PF2010 controller

[YongNei]

Hi,i need to do data transfer between two or more FP2010 controller.e.g. FP2010(A) & FP2010(B).
FP2010(A) need to transfer the measurement (from its I/O module) to FP2010(B) to do the data analysis.These data transfer should be synchronous btw two controller to prevent data lost.
From the vi used in the attachment,i encountered some problems at:
(1) Error 33172 occurred while publishing the data.Can i create and publish data under different item name?
(2) How to synchronies the read & write btw contorller?
All controller are communicating with each other directly without the need of a host computer to link them together

Is there any other method to do fast data transfer betwe
en controller?

Hi YongNei,

You were succesful in omiting enough information to make it very difficult to answer!

Please post your example.

Please tell us what version of LV-RT you are using.

Please define what you concider "fast data transfer".

Have you concidered mapping the FP tags of FP2010(A) to FP2010(B) and vise versa?

WHat exactly has to be syncronized?

If you have something that is close to working, share that.

Well, that as far as I can go with the info you have provided. Depending on the details, what you are asking could be anything from trivial to impossible with the currently available technology. I just can't say.

It would probably be a good idea to start over with a fresh question (sorry) because not many people are going to know what a a "
PF2010" is and I can not guarentee that I will be able to get back to you personally until next week-end.

Trying to help you get an answer,

Ben
