Yokogawa’s Centum PRM/DTM messages
When the secondary sensor fails, alarms will be displayed in the PRM (Plant Resource Manager)
via yellow circles next to the device, as shown below. These yellow circles indicate that
something in your process needs attention. To investigate this further, right click on the affected
device, and choose DTM Works… This will open the DTM (Device Task Manager).
In the DTM, the device status will indicate a Failed status in the Process Variable Overview section,
shown below.
