Data points

In the table "Data points" all configured tags are shown as data points grouped according to
tag types.
Data points for the read direction
● Digital inputs
Apart from the configured process tags, here you will find two status tags for error
messages (STATUS_ERROR) and for the operating status of the RTU (STATUS_RUN)
that can be read by the communications partner.
● Analog inputs
● Counter inputs
These are event counters (DI0 and/or DI1) and analog memory bits configured as
counters.
You can also find the tag for the next communication cycle here:
– STATUS_NEXT_COM_CYCLE
There are the following tags for the mobile wireless status:
– MOB_SIG_QUAL
– MOB_CELL_ID
– MOB_TX_KB
– MOB_RX_KB
The remaining capacity of the battery life (HW2) is indicated by the following tag:
– BAT_RES_CHARGE
Tags for the extension board and GPS which are created as counter inputs are also
displayed.
Data points for the write direction
For the values that the communications partner writes in the process direction, the following
tag types are available:
● Digital outputs
● Aanalog memory bits configured as an analog value.
Analog memory bits configured as counters cannot be written. In addition, no tag of the
extension board can be written.
The data points of the protocols TeleControl Basic, ST7 and "IEC" can be used both in the
read direction (in) and the write direction (out).
Processing of process data
Data points
When processing process data, the inputs and outputs are processed by the program and
saved in the address areas input, output and bit memory of the RTU. The individual
