Status Areas
Section 9-1
9-1 Status Areas
A Bit Slave 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 values set by the user for each function in that Unit. When
any of the bits in the status area of the slaves connected to the Master Unit
turns ON, the corresponding bit (bit 12 is for warning status area notices and
bit 13 is for alarm area notices) of the status flag in the Master Unit turns ON.
The Bit Slave Unit's status area information can be read by using the CX-Inte-
grator or explicit messages.
Warning Status Area
The Bit Slave Unit’s Warning Status Area contains the following 16 bits. These
bits indicate minor errors in the Unit.
Note For Bit Slave Units with Compact Connectors, all bits are reserved.
