7.6 Example of a Parameterization and Measured Value Evaluation for
SICAM P855
7.6.1 Task Definition
✧ Set the parameters via the Ethernet interface using the default IP address set upon delivery of the device.
✧ Configure SICAM P855 according to the topology.
✧ Parameterize the indication of a measurand limit violation for V
ab
> 11 kV with 10 % hysteresis and name
the indication.
✧ Parameterize a binary output that is switched on for the duration of the measurand limit violation.
✧ Communicate via serial communication using device address 1, with a baud rate of 19.2 kbit/s, even
parity, full access rights, and a monitoring time of 1 min.
✧ Parameterize the Ethernet communication according to the network configuration specified by the system
operator.
✧ Assign any name and specify the time/date format as YYYY-MM-DD and the time in 24-hour format.
✧ Parameterize the Measurement recorder with an averaging time of 2 hours and activate the averaging
recorders for minimum and maximum values. Record all voltage harmonics.
✧ Allocate 50 % storage capacity to the Measurement recorder.
✧ Take over the factory-set report configuration.
✧ Activate the device configuration you have created as the active parameter set.
✧ Perform measurements, acquire the measurand limiting value indication and record the measured values
as defined in the task.
