 Slave Status Overview
The CJ1W-PRM21 Master DTM Diagnosis User Interface provides a comprehensive overview of
the slave device status without having the user to open all the slave DTMs. The overview is pre-
sented in the Monitoring - Slave Status tab of the user interface and displays only the standard PRO-
FIBUS diagnostics flags. An example is shown in the figure below. For the extended, non-standard
diagnostics see section 5-7-2 Monitoring Slave Status.
The upper half of the window - the Slave Status Flags box - presents the status of each slave device
using colored indicators. The colors are listed in the table below.
Indicator color
Grey
Red
Orange
Yellow
Green
Any other color than green or grey indicates that new diagnostics have been received from the
associated slave device since the last time the diagnostics was monitored.
