The RCAD server utilizes TCP/IP technology to connect RCAD clients to
the DCS to allow monitoring, uploading CFG files, downloading CFG files,
online configuration changes and other online features.
Because it uses TCP/IP, users may use the Internet as a means of maintaining distant plant sites from engineering centers.
What does the RCAD Server do?
Besides allowing users to communicate to the Infi-90 DCS, the RCAD
server also provides the following benefits:
1. Built in firewall to restrict unwanted users from trying to
gain access to the DCS.
2. Permits sharing a single Computer Interface Unit (CIU, ICI
3. Automatic module arbitration to permit only 1 person at a
time to write to a module.
4. Provides up to 10,000 blocks of monitoring cache.
Monitoring requests by clients are instantly returned to the client
resulting in faster software use.
