Hi, e'body o'there

i,m developed data acq using serial dual counter canberra 512 , act. it run but can i get the data the aother way as through serial port on cFP 2220 is it practical due to remote condition or long distance ( next room)

Hi Zainu,

I am a little confused on what question you are asking. If it is whether you can use the cFP-2220 to interface with a serial device, then yes you can. As far as length limitations with RS232 cables, anything less than 10 or 15 meters should be no problem, and specific length requirements are defined by bit rate, shielding, etc.

I hope this information is helpful.

Hi, Stephen S.

i am happy for your answer, sorry to give you a little bit confused. i want to get  the data from the dual counter ( rs 232 compatible)  not directly connected to pc but through cFP 2220 ( field pt, using rs 232 port) and connected to pc(controller) using ethernet. Is the proggramming need to  deploy to cfP or not for better reliable

Zainu,

You will need to embed a Target vi on the cFP that communicates with your counter via RS232.  Since the cFP uses VISA functions as well, the vi that does the RS232 read should run on the cFP as pretty much as you have written it.  The only difference is that you need to create a way to make the counter readings available to the PC.  The simplest way to do this is to publish the counter readings using a Shared Network Variable that is hosted on the cFP.  You can then read the Shared Network Variables in a Host vi that runs on the PC.
