Status Areas
Note
The Hold Flags are used with the peak/bottom hold and top/valley hold func-
tions. They are used to control the hold execution timing from the Master Unit.
They are allocated in the Master Unit using the following data format (1 word
(2 bytes)).
Each bit is described in the following table.
A transmission delay may occur between when the Master Unit's power is
turned ON and the status of the Hold Flag is transferred to the Temperature
Input Unit.
A Temperature Input Unit has two status areas. The flags 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 Temperature Input Unit's status area information can be read by using the
CX-Integrator or explicit messages.

The hold function is performed for Tem-
perature Input 0 while this flag is ON.
The hold function stops and the last
value is held when the flag goes OFF.
The hold function is performed for Tem-
perature Input 1 while this flag is ON.
The hold function stops and the last
value is held when the flag goes OFF.
The hold function is performed for Tem-
perature Input 2 while this flag is ON.
The hold function stops and the last
value is held when the flag goes OFF.
The hold function is performed for Tem-
perature Input 3 while this flag is ON.
The hold function stops and the last
value is held when the flag goes OFF.
