Modbus Tcp User Parameters - ABB PCS100 AVC-20 User Manual

86 PCS100 AVC-20 User Manual
The Modbus TCP server responds to reads from the cached addresses in typically less than 3 milliseconds.
However, the latency in a parameter changing value (the time it takes for the cached values to be refreshed) is
typically around 3 seconds.

Modbus TCP User Parameters

The following table lists the user parameters available from the PCS100 AVC-20.
The address listed is the offset (raw) address. For 4xxxx address add 40001 to the offset address. Each address
refers to a 16-bit register.

Voltage (line-to-line RMS volts) = raw value
e.g., raw value = 480
Voltage = 480V
Frequency (Hz) = raw value / 32
e.g., raw value = 1920
Frequency = 60Hz
Current (RMS Amps) = raw value
e.g., raw value = 500
Current = 500A
Voltage (line-to-line RMS volts)
= raw value x 13 Supply Voltage / 8192
e.g., raw value = 7782
rated voltage = 480V
Voltage = 456V
Voltage (% of rated voltage)
= raw value x 100 / 8192
e.g., raw value = 8192
Voltage = 100%
Current (RMS Amps)
= raw value x 10 System Current / 8192
e.g., raw value = 5792
rated current = 500A
Current = 354A
Current (% of rated current)
= raw value x 100 / 8192
e.g., raw value = 4096
Current = 50%
