hitesh,
Yes, you may dial in to the Compact Logix PLC using the RADKIT modem. But how will this help to access the RSView Runtime? The only way I know of to get into RSView from a remote location is to purchase the RSView Active Display Server program. I have used this one to access RSView remotely via a modem. You can actually run the project from a remote location using the Active Dispaly Server program. This program runs concurrently with RSView, giving it the front end needed for remote access. I recommend that you do not leave the modem connected if you go this route. Any hacker would be able to break in and start/stop your equipment at any time.
