In our plant we are using Honeywell DCS, Experion PKS, R301 Version with C300 controller. We have both foundation Fieldbus and HART type instruments.
When I try to modify and load any Analog Tag number online, the Tag number immediately goes offline for a moment till the download completes. The system is unable to update the data from the field till the download gets completed. In the case of digital I/O's the downloaded DI tag goes to offline. For example if we try to download a DI (running indication) of a pump, which is running, the Pumps stops automatically as the DCS sends stop command automatically during the start of downloading.
This means that we are unable to download any Tag numbers online. How to overcome this problem?
