F650 DIGITAL BAY CONTROLLER
d-5
IEC104 IOA BINARIES:
Starting Information Object Address for Single Points.
IEC104 IOA DOUBLE POINTS:
Starting Information Object Address for Double Points.
IEC104 IOA ANALOGS:
Starting Information Object Address for Analog Inputs.
IEC104 IOA COUNTERS:
Starting Information Object Address for Counters.
IEC104 IOA COMMANDS:
Starting Information Object Address for Single or Double Commands.
IEC104 IOA ANALOG PARAMETERS:
Starting Information Object Address for Parameter of measured value. Each
Measured value has a Parameter of measured value associated with its
threshold.
The F650 relay has a custom Binary Inputs points list, called User Map; it is common for any protocol. In the case of IEC 104
Protocol, those points are GROUP1 and GROUP2.
The IEC 104 User Map can be configured using the
EnerVista 650 Setup
software in
Setpoint > Relay Configuration >
Control Events
.
The User Map contains 128 Binary Inputs. To each point of the User Map, assign any of the binary states of the F650 relay.
It is also possible to combine those states using OR and NOT functions. These states are: contact inputs and outputs, virtual
outputs, protection element states, PLC states, etc. The User Map always has a size of 128 Binary Inputs. Points in the User
Map that are not configured have a zero value in the answer.
It is possible to implement more complex logic than simple OR and NOT using the
PLC Editor
tool in
EnerVista 650 Setup
in
the menu
Setpoint > Logic Configuration
.
These complex signals (Virtual Outputs) can be assigned to the binary points in
the Control Events configuration for the IEC 104 user map.
Groups of Data
The data is organized into groups in order to provide values when the controlling station requests them by a general or
group interrogation.
Group 1, 2 & 4 are set by the 256 Single Points (M_SP_NA_1).
Group 3 is set by the 16 Double Points (M_DP_NA_1).
Group 5 and 6 are set by the120 Analog Inputs, short floating-point (M_ME_NC_1).
Group 7 is set by the 120 Parameter of measured value, short floating-point (P_ME_NC_1).
These 256 Single Points, 16 Double points and 120 Measured Values are also sent as a response to a General Interrogation.
The 20 Integrated Totals (M_IT_NA_1) has its own Counter Group and it is sent as a response to a General Request Counter.
