Cautions for Your Safety
Read the manual carefully before installing, running and maintenance for proper operation.
Before using, master the knowledge of the equipment, safety information and all of other
notes.
This manual uses two safety flags to indicate different levels of danger.
WARNING
A handling error could cause serious physical injury to an
operator and in the worst case could even be fatal.
●Always take precautions to ensure the overall safety of your system, so that
the whole
system remains safe in the event of failure of this product or other external factor.
●Do not use this product in areas with inflammable gas. It could lead to an explosion.
●Exposing this product to excessive heat or open flames
could cause damage to the
lithium battery or other electronic parts.
●Do not open the secondary side of CT during power on the primary side current.
It might cause electric shock or CT breakdown.
CAUTION A handling error could cause serious physical injury to an operator
or damage to the equipment.
●
To prevent abnormal exothermic heat or smoke generation, use this product at the
values less than the maximum of the characteristics and performance that are assured
in these specifications.
●Do not dismantle or remodel the product. It could lead to abnormal exothermic heat or
smoke generation.
●Do not touch the terminal while turning on electricity. It could lead to an electric shock.
●Use the external devices to function the emergency stop and interlock circuit.
●Connect the wires or connectors securely. The loose connection might cause abnormal
exothermic heat or smoke generation.
●Do not allow foreign matters such as liquid, flammable mat
erials, metals to go into the
inside of the product. It might cause exothermic heat or smoke generation.
●Do not undertake construction (such as connection and disconnection) while the power
supply is on.
●Never remove the terminal block under applying current to load.
It might cause electric shock or CT breakdown.
●Do not use at secondary side circuit of inverter. It might cause exothermic
heat or
damage.

Chapter 1 Communications
1.1 Communication Procedures
Communication starts with command transmission from the host computer (hereafter Master) and ends
with the response of Eco-POWER METER (hereafter Slave).
• Response with data
When master sends reading command, slave responds with the
corresponding set value or current status.
• Acknowledgement
When master sends setting command, slave responds by sending
the acknowledgement.
• Negative acknowledgement
When master sends a non-existent command or value out of the setting
range, the slave returns negative acknowledgement.
• No response
Slave will not respond to master in the following cases.
• Global address “FF” (MEWTOCOL) is set.
• Broadcast address “00H” (Modbus protocol) is set.
• Communication error (framing error, parity error)
• CRC-16 discrepancy (Modbus RTU mode)
• CS discrepancy (DL/T645)
1.2 Communication timing
◆The minimum access time from the master is 1 sec. (Minimum time for update the data)
Eco-POWER METER may not response due to noise and so on, be sure to check that it receives the
response from Eco-POWER METER.
◆In order to improve the communication quality, we recommend to send the transmission again.
Communication timing of RS485
◇Eco-POWER METER (Slave) side
When Eco-POWER METER (Slave) starts transmission to RS485 communication line, it is arranged
so as to provide an idle status transmission period of about 1 to 99ms (setting available) before
sending the response to ensure the synchronization on the receiving side. After sending the response,
master can disconnect the transmitter from the communication line within transmission period 20ms.
◇Master side (Cautions of setting a program)
At communication, keep the following conditions.
1) Set the program so that the master can disconnect the transmitter from the communication line
within the transmission period of about 20ms after sending the command in preparation for
reception of the response from Eco-POWER METER (Slave).
2) To avoid collision of transmissions between the master and Eco-POWER METER (Slave), send a
next command after checking that the master received the response.

1.3 MEWTOCOL Communication
1.3.1 Overview of MEWTOCOL-COM (RS485)
◆Command and response functions
The computer sends commands (instructions) to Eco-POWER METER, and receives responses in
return. This enables the computer and Eco-POWER METER to converse with each other, so that
various kinds of information can be obtained and provided.
①Commands
Computer Eco-POWER METER
②Responses

Explanation
Header ％ 25H

Command ＃ 23H

message.

＄ 24H
Indicates that the data comprises a normal response
message.
Error

！ 21H

when an error occurs.
Terminator
CR
0DH
Indicates the end of a message.
◇Destination and source AD (H), (L)
Two-digit decimal 01 to 99 (ASCII codes)
Command messages contain a station number for Eco-POWER METER that receives the message.
When FF (ASCII code table) is used, however, the transmission is a global transmission (sent to all
stations at once).
Note) When a global transmission is sent, no response to the command message is returned.
◇Block check code Bcc (H), (L)
Two- digit hexadecimal 00 to FF (ASCII codes)
These are codes (horizontal parity) that are used to detect errors in the transmitted data.
If “**” is entered instead of “Bcc”, however, messages can be transmitted without the Bcc. In this case,
the Bcc is included with the response
◇Error code Err (H), (L)
Two- digit hexadecimal 00 to FF (ASCII codes)
These indicate the content if an error occurs.
◆Bcc (Block Check Code)
-The Bcc is a code that carries out an error check using horizontal parity, to improve the reliability of
the data being sent.
-The Bcc uses an exclusive OR from the header (%) to the final character of the text, and converts the
8- bit data into a 2-character ASCII code.
