When the RTU is turned on, the outputs will be set to the initial conditions.
These values will remain on the outputs until an incoming message changes the
outputs or until a fail-safe condition is set. Both used and unused inputs can have
an initial condition and a fail-safe value.
This RTU can be programmed to expect a check-in from other units. If this
check-in message is jammed or the other RTU fails to respond, this RTU can set
a fail-safe condition. The value in this field is the amount of time this RTU must
go without receiving a message from the other RTU before it can set its fail-safe
state. Each from ID can have only one receive check-in time. Place this check-in
time in the first column which contains the appropriate from ID.
The letter in the fail-safe state field indicates which fail-safe state will be used
upon loss of signal from the unit listed in from ID. The fail-safe states are listed
in the lower right corner of the system configuration screen.
2.3 Function Keys
The bottom two rows of the RTU input/output configuration screen form the
function key menu. Select an input field and press Fl to display help for the
selected field. Press F2 to display this full help document. Press Fl O to return to
the RTU system configuration screen.
3.0 RTU SCADA Configuration Screen
The SCAD A configuration screen lists four SCAD A points which can be stored
in the RTU EEPROM. The function key menu provides access to the full
SCADA configuration. SCADA configuration allows the user to connect one
RTU to a supervisory control and data acquisition program and poll remote
RTU's over RF. The SCADA program must use the MOD BUS protocol. The
SCADA configuration must reside in the one RTU connected directly to the
SCADA program. That RTU uses the routing information in the SCAD A
configuration to send an RF message to the addressed RTU.
