1 Setup
This chapter describes the setup procedure required to use the communication functions
and the communication specifications of the UPM100 universal power monitor.
Hereafter, the UPM100 universal power monitor is simply referred to as the UPM100.
1.1 Setup Procedure
Set up the communication functions on the UPM100 as follows:
Set up the communication function parameters of the UPM100.
For the UPM100 with display function, set up the communication conditions using the
front panel keys.
For the UPM100 without display function, set up the communication conditions using
the front DIP switches. (See the user's manual of Model UPM100 Power Monitor
<Initial Setup Operations>.)
Connect a higher-level device and a UPM100.
(See the user's manual of Model UPM100 Power Monitor <Installation>.)
Create communication programs for the higher-level device to perform communication.
(See "4. PC Link Commnication" or "5. MODBUS Communication" for the communication
protocol. See "6. Functions and Usage of D Registers", "7. Functions and Usage of I
Relays" and "8. UPM01 Communication" for the data storing.)
010101E.EPS
To avoid an electric shock, be sure to turn off the power supply source to the
equipment involved before you start wiring.
Note
• In the case of PLC (MELSEC:Mitsubishi Electric Corporation’s sequencer), “B” is for (-), and “A”
is for (+).
• Do not share the grounding wire with another instrument. Doing so may result in a failure of the
instrument. Use crimp terminals at cable ends.
Note Create communication programs referring to the documentation of each higher-level device.
Higher-level devices : PCs, PLCs (sequencers), touch panels, and others.

3 Procedures for Setting UPM100/UPM101 Functions
To set the functions of the UPM100, use the protocols described in “4. PC Link
Communication,” “5. MODBUS Communication,” or “8. UPM01 Communication” according
to the instructions in this chapter.
For details of each function, refer to the standard manuals that come with the UPM100.
For set value ranges, initial values, and data backup for registers, refer to “6. Functions and
Usage of the D Register.” D Register numbers are explained in this chapter, but refer to
Chapter 6 also for reference numbers for MODBUS communications.
The UPM100 offers registers for floating-point data. To perform settings via communication
starting from larger digits, floating-point data is displayed by IEEE754 (single precision).
Note
• The UPM100 has data (D register) the unit of which is two words. When 2-word data need to
be written or read, writing or reading operations must be performed for the 2- word data at the
same time.
• Even if data written to the D register is out of the effective range, a normal response is returned.
The part of the written data within the effective range becomes effective on the UPM100 when
the equivalent setting change status is written for that data.
Chapter 3 Procedures for Setting UPM100/UPM101 Functions

3-2 IM 77C01H01-10EN
3.1 Basic Setting
3.1.1 Setting of VT Ratio
[Procedure]
1. Write a VT ratio to the two D registers in the table below. The data type is 4-byte floating
point.
2. After writing that value, write “1” to the setting change status register, D0072.
D Register Reference No. H No. Description Effective Range
D0043 40043 002A VT ratio (float, lower 2 bytes) 1 to 6000
D0044 40044 002B VT ratio (float, upper 2 bytes)
D0072 40072 0047 Setting change status If other than 1: Invalid
If 1: Writing is executed
Default VT ratio: 1 (4-byte floating-point data: 3F800000)
[Example]
To set the VT ratio to 10.0:
For station number 01, use PC link communication (without checksum) and the random write
command as shown below:
If 10.0 is converted into a 4-byte floating-point value, the value is 4120 0000.
[Command]
[STX] 01010WRW03D0043, 0000, D0044, 4120, D0072, 0001 [ETX] [CR]
[Response]
[STX] 0101OK [ETX] [CR]
Note
• When the VT ratio is changed, already integrated values of active energy, reactive energy,
apparent energy, optional electric energy, and regenerative energy will return to 0.
• Set the VT and CT ratios so that [Secondary rated power] x [VT ratio] x [CT ratio] is smaller than
10 GW.
