Configuring Communication Protocols
Defines the maximum repetition rate in variations
per hour (equal or less than) for rapid voltage
changes. Voltage changes at higher rates are not
classified since they will be subject for flicker.
Defines the period of time for the short-term
flicker evaluation. The standard setting of 10
minutes can be temporarily changed in the device
for testing purposes.
Defines the highest harmonic order included in
the THD evaluation.
Defines the highest harmonic order for evaluation
of the harmonic voltages.
Enables the evaluation of the interharmonic
voltages
Defines the highest interharmonic order included
in the THD evaluation.
Interharmonics,
up to order
Defines the highest harmonic order for evaluation
of the interharmonic voltages.
Enables the evaluation of the mains signaling
voltages
Specifies the mains signaling frequency for the
compliance evaluation
Specifies the mains signaling frequency for the
compliance evaluation
Specifies the mains signaling frequency for the
compliance evaluation
Specifies the mains signaling frequency for the
compliance evaluation
Clearing EN50160 Evaluation Counters
To clear the present contents of the EN50160 evaluation
counters before starting your EN50160 evaluation, check the
On-line button, select Reset from the Monitor menu, and then
Click on the “Clear EN50160 Counters” button (for more
information, see Resetting Accumulators and Clearing Log
Files).
Configuring Communication Protocols
This section describes how to customize protocol options for
use with your application software.
Configuring Modbus
Modbus Point Mapping
The PM175 provides 120 user assignable registers in the
address range of 0 to 119. You can re-map any register
available in the meter to any assignable register so that
Modbus registers that reside at different locations may be
simply accessed using a single request by re-mapping them to
adjacent addresses.
