Status Areas
A Digital I/O Slave Unit has two internal 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 Digital I/O Slave Unit's status area information can be read by using the
CX-Integrator or explicit messages.
Warning Status Area
The Digital I/O Slave Unit's Warning Status Area contains the following
16 bits. These bits indicate minor errors in the Unit.
