Modbus MB1 Driver for iFIX

[Sajid]

Hi friends, I have a set-up where I am dialing through a modem ,using MB1(Modbus) with iFIX,to poll a modbus slave.Everything seems to work fine.The driver is able to dial a particular modem at the slave end and the data is being displayed on an iFIX screen. Once after dialing the call remains open and the driver never hangs up.This is not how I would like my set-up to work.I would like to have the driver dial,say, every 30 mins or 1 hour,acquire data and then hang up the line.But this is not happening. Please help me with the setting I need to make in the driver Power Tool so that I get the desired response. Thanks.
