Group 2, so when a general interrogation or group 2 interrogation takes place all the
measurands are included in the response. Also, there is a cyclic data period setting where it
is configured in the scan period to send the measurands to the Master. And the last way, is
by sending spontaneously when a deadband overflow takes place. The IEC104 Channels
sub-menu is shown below.
Commands are executed over the Binary Outputs. The first 8 Binary Outputs are
configured to receive Select/Operate Commands and the next 8 Binary Outputs are
configured to receive Direct Execute Commands.
The IEC104 CHANNEL 1 PORT and IEC104 CHANNEL 2 PORT settings select the
communications port assigned to the IEC104 protocol for each channel. When this setting
is set to "Network - TCP", the IEC104 protocol can be used over TCP/IP on channels 1 or 2.
The IEC104 NETWORK CLIENT ADDRESS settings can force the 850 to respond to a
maximum of two specific IEC104 masters which own the configured IP Addresses. The
settings in this sub-menu are shown below.
"IEC104 Channel 1 Port" takes the "Port Number 1" and "Client Address 1" to allow or reject
connections. The same method is used by channel 2.
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 is set by the 96 Single Points (M_SP).
Group 2 is set by the 32 Measured values (M_ME).
Group 3 is set by the 32 Measured thresholds (P_ME).
These 96 Single Points and 32 Measured Values are also sent as a response to a General
Interrogation.
The Integrated Totals (M_IT) has its own Counter Group 1, and it is sent as a response to a
General Request Counter.
The point map for the 103 is different from the one shared by the IEC104 and DNP
protocols. IEC 60870-5-103 serial communications protocol is supported on the rear RS485
port only.
The DNP, 103 and Modbus can not be enabled simultaneously. Only one instance of
DNP3.0, IEC 103 or Modbus can run on the RS485 serial port.

FlexLogic section of the individual 850 instruction manual.
The user must pay attention when configuring the function type and information number
of the different points, because they must be unique. There is no mechanism in the
EnerVista 8 Series Setup software or the front panel HMI to detect duplication of the
information index.
The IEC 60870-5-103 point lists always begin with point 0 and end at the first "Off" value.
Since IEC 60870-5-103 point lists must be in one continuous block, any points assigned
after the first "Off" point are ignored.
