1.1 Function Overview

In this manual, PW8001 is represented as the instrument.

This instrument functions as a Modbus/TCP server. You can control the instrument and acquire

measurement data by sending messages from a Modbus client instrument to this instrument.

PW8001

Modbus client

The instrument uses TCP/IP port 502 as a listening port for the Modbus/TCP communication.

In addition, the unit ID (server address) for the Modbus/TCP server of this instrument is 1. Any

messages with a unit ID other than this value cannot be accepted.

1.2 Function Code

The function codes supported by the instrument are as follows.

0x03

Reading the holding

Reading the input register Reads up to 125 sets of data continuously from the input

0x04

0x06

Reads up to 125 sets of data continuously from the

1.3 Specifying a Register

You can specify a register from the Modbus client instrument as follows.

1.3.1 When using a commercially available SCADA system, etc.

Specify the Ref No. (reference number) listed in “3.1 Register Map” and “4.1 Register Map”.

Example: Specify Ref No. “30021” to acquire Urms1 Float lower 2 bytes “Input register:0021”.

1.3.2 When using a communication program created by the customer

Specify the Hex No. (relative number) listed in 3.1 Register Map” or “4.1 Register Map”.

Example: Specify Hex No. “0014” to acquire Urms1 Float lower 2 bytes “Input register:0021”.

2.1 Register Overview

In this instrument, measurement data and settings data are assigned to the internal register for

Modbus/TCP.

When the client instrument sends messages to the instrument via Modbus/TCP communication

and the internal register of the instrument is read and written, measurement data can be acquired,

integration can be started, etc.

2.2.1 Input register non-assigned area

Any area with input register numbers skipped (register No. 0847 to 1000, etc.) is an area to which data

is not assigned. This area can be read with a Modbus message, however, the value is all NAN

(0x7FC00000). Access to the address beyond the suffix of the input register (register No. 8040)

generates an error.

Example: 0847 to 1000

HIOKI PW8001A968-00

Float is IEEE single-precision floating-point format (32-bit) data.

One Modbus register is fixed to 16 bits and the Float format data is divided and saved to two registers

with 16 bits each.

As all Float format data for this instrument is arranged in Little Endian order (in order of lower 16

bits and upper 16 bits), specify “Little” for the data order in which Float format data is handled on

the client side.

Example: When CH1 voltage RMS value Urms1 is 100 V, the reading of the register is as follows.

Input register: 0021 = “0x0000”

Input register: 0022 = “0x42C8”

Data when an error occurs is as follows.

0x7FC00000 (NAN)

3.3 Harmonic Measurement Items

The harmonic measurement items for the input register (register No.: 4001 to 4240) are all primary

measured data in the initial settings. By specifying the harmonic order in Harmonic Order (register No.:

0008) of the holding register, you can acquire the measured data of any order.

register harmonic order, see “4.2.8

Example: If you specify “100” for the harmonic order (register No.: 0008) for the holding register, the

harmonic measurement items (register No.: 4001 to 4240) for the input register are all 100th

measurement data.

HIOKI PW8001A968-00

3.5.1 Registration of optional output items

For the input register optional output items (register No.: 6001 to 8000), up to 1000 optional output

items can be assigned using the communications command :MODBus:ITEM.

register map under “3.1.8 Optional output items”.

output items is assigned to this area.

items”.

The optional output item registration is reset when the power is turned on again and “Pattern 1” of the

preset output items is set every time the instrument starts up. The registration information of the

optional output items cannot be saved in the settings file.

For the procedure to assign and preset output items using a communications command, see the

PW8001 Communications Command Instruction Manual.
