Binary input data: Binary input data is used to monitor two-state device operations
such as the position of a circuit breaker. The user can configure up to 96 Binary inputs.
All binary inputs are configured from Flexlogic operands.
Binary output data: Binary output data is used to control two-state devices such as
the tripping or circuit closing of a circuit breaker. The 869 can be configured to support
up to 16 Binary outputs. The slave's Binary outputs are automatically mapped into the
869 virtual inputs starting at virtual input 1. Please note that the number of Binary/
Control outputs is configurable. The user can configure a subset that supports dual
point control. This subset starts at address 0.
Analog input data: Analog input data is used to monitor analog signals such as
voltages, currents, and power. Up to 32 analog points can be mapped to the master.
Analog output data: Not supported in the 869 .
Time stamps
Count input data: Count input data could represent a cumulative quantity such as
kilowatt-hours of energy. Up to 16 counter points can be mapped to the master.
