Function
Real time control of DP master station
Connect Siemens ET200 remote IO, frequency converter, valve positioner, analyzer, weighing instrument and other DP slave stations
Complete equipment diagnosis
Real time uploading of DCS alarms for bus disconnection, short circuit, offline slave station, and communication timeout
Non periodic read/write V1 function
Online modification of on-site equipment parameters and reading of equipment fault logs without the need for downtime
Single bus architecture
Single channel DP, if bus redundancy is required, two independent DP buses need to be mounted on each CM772F separately
