Rules For Configuring The Data Point Index; Process Image, Type Of Transmission, Event Classes - Siemens SIMATIC TeleControl DNP3 Configuration Manual

● Value monitoring
Only for commands and outputs of a station module
When this option is activated, the current value of the data point, which can be set by the
master, is mirrored back from the station to the master. Furthermore, the trigger options
of the data point can be enabled to configure the triggering of the transmission.
● Type of transmission
For the type of transmission, see section Process image, type of transmission, event
classes (Page 113).
● Read cycle
Only for inputs
For the read cycle, see section Read cycle (Page 115).
● Response to general request
Enables a station data point for the response to general requests. If the function is
disabled, the value of the data point is not sent to the communications partner following a
general request.

Rules for configuring the data point index:

Configuration of the data point index
The following rules apply to configuring the data point index.
● Data point indexes must be unique within each of the following object groups:
– Binary Input / Binary Input Event
– Binary Output / Binary Command
– Counter / Counter Event
– Analog Input / Analog Input Event
– Analog Output
– Octet String / Octet String Event
● Indexes of two data points in different object groups can be identical.

in the image memory are transferred only after being called by master station TIM.
Events are also stored in the send buffer and can be transferred unsolicited.
