group. On receipt of a new pulse, the previous requirement is reset and the
new requirement applies.
Note:
Selection GCP source
As a rule, it is possible to choose between various devices for recording
parameters (i.e. voltage, power, power factor) at the grid connection point
(GCP).
Power quality analyser (PQA) and main computer are currently supported as
the source. The PQA is connected to the WEB`log directly.
Requirements of main computers are received via the RS232 connection of
the PCU.

Select the type of the inputs/outputs in accordance with the
wiring. Electric data on the input/output are saved in the PCU
data sheet.
The PQA Modbus client ID is assigned to the PQA device
types (see section 6.2). The client ID is established by
scanning for serially connected devices or entered manually.
The parameters for the IEC 60870-5-101 configuration must
be coordinated with the main computer.
