measured phase or channel according to network configuration:
- phase or channel 1,
- phase or channel 2,
- phase or channel 3,
- phases or channels sum or mean.
- alarm parameters:
detection type, high threshold or low threshold,
threshold,
hysteresis.
The alarm
works in this way:
-
High threshold
detection: .alarm is activated when measure goes beyond threshold,
.alarm is removed when measure goes below threshold less hysteresis.
-
Low threshold
detection: .alarm is activated when measure goes below threshold,
.alarm is removed when measure goes beyond threshold more hysteresis.
6.2) Energy meter:
The relays configuration in meter is composed of 2 rubrics:
- measures parameters:
measured value:
- consumed or generated active energy,
- inductive or capacitive reactive energy,
measured phase or channel according to network configuration:
- phase or channel 1,
- phase or channel 2,
- phase or channel 3,
- phases or channels sum.
- meter parameter:
impulse load value (kW.h or kvar.h).
7) Communication:
7.1) MODBUS:
The communication configuration is composed of 3 rubrics:
-
device address
in communication network (1 to 255),
-
speed
(1200, 2400, 4800, 9600, 19200, 38400 bauds),
-
parity
(even, odd, without).
7.2) PROFIBUS:
The communication configuration is composed of 2 rubrics:
-
device address
in communication network (0 to 126),
-
speed
(9600, 19200, 93.75K, 187.5K, 0.5M, 1.5Mbauds)
The data exchange are the measure in 32b integer and the command for reset the energy.
It is necessary to also configure the data format which will be used in the communication:
- data in "NORMAL" mode : 32 bits integer, MSB send first.
- data in "SPECIAL" mode : 32 bits integer, LSB send first.
For more details, see RS485 communication Modbus or Profibus chapter at the end of handbook.
