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.
