fors-device_status

This data flow is received from the Other ITS roadway equipment terminator and contains status and fault information for an indicator (e.g., ramp meter controller, intersection controller). The data flow can contain the actual state of operation of the indicators. It is used for coordination between peer indicators or for information transfer between devices functioning in a hierarchical arrangement. It may also be used to exchange information between a Signal System Master (SSM) and Signal System Local (SSL) equipment. In this case, the Other RS terminator represents the indicator from which status is being sent. This data flow consists of the following items each of which is defined in its own DDE:

f_other_rw_ic_status_to_ic
+ f_other_rw_fc_status_to_fc

Sub Data Flows

• f_other_rw_fc_status_to_fc
