10-1 Status Areas
An Repeater Unit has two status areas: the Warning Status Area and the
Alarm Status Area. The status flags in these areas are turned ON and OFF
based on the threshold/monitor values set for each function in that Unit. If any
flag in the Warning/Alarm Status Areas in the Repeater Unit turns ON, the
corresponding status flag in the Master Unit to which the Repeater Unit is con-
nected turns ON. Bit 12 in the Master Unit corresponds to the Warning Status
Area and bit 13 corresponds to the Alarm Status Area.
The Repeater Unit's status area information can be read by using the CX-Inte-
grator or explicit messages.
Warning Status Area
The Repeater Unit’s Warning Status Area contains the following 16 bits.
These bits indicate minor errors in the Unit.
Master Unit
The Repeater Unit has two status areas:
the Warning Status Area and the Alarm Status Area.
Transmitted
to Master Unit
Repeater Unit
The Master Unit has a Warning Status Bit and Alarm Status Bit.
The status of each of these bits is an OR status of the bits in the
status areas in the connected Slave Units.
