Dear List Members,
I have to collect certain tag information's from the intellution's FIX 7.0 software. I have developed an application in VB which is reading the data through DDE from FIX. After collection of this data I am transferring this information on a serial port using MSCOMM. I have tested this software with an in-house test set-up where the software is working perfectly giving the desired results.
I have tried deploying this solution at the site. At site there are 2 comports, one on which the FIX software is communicating to the fieldst server adevice on Modbus whereas on the second port a modem is connected which was being used for RAS ( remote access services). We have uninstalled the RAS hence the comm. port is free. Fix software has been started properly after removing the RAS. We have tried running the developed application on com port 2 after starting the Fix software. We are not able to access the comport as the application software is giving an error " Port already opened". We have tried running our application without the Fix software and it has started without giving an errors but we are not able to receive any data at the other end.
Is there any application / services preventing the access of comport ? is there any other task ( Alarm etc.. ) in Fix software holding the
access of the comport ? Has any body faced such a problem ?
Any pointers in this direction would be highly appreciated..
Thanking in anticipation
