Status Areas
A Counter Unit or Positioning Unit has two status areas. The Unit’s Status
Flags are turned ON and OFF based on the threshold/monitor values set for
the functions in the Unit. A flag in the Communications Unit will be turned ON
only when the corresponding flag has been turned ON in one of the status
areas.
The Communications Unit’s Status Flag information is transmitted to the Mas-
ter. The Counter Unit’s or Positioning Unit’s status area can be read from a
Programming Device.
