Software Specifications

Items Details
Operation Mode Normal Mode Modes when operated normally
Safe Mode Modes when recovering from disasters or maintaining the device
Logging Function The logging function is configured with collected data and event logs.
Collected data: The data collected from measurement devices are
saved in the internal memory.
Event Log: Log of EQ100-E monitoring alarm, device alarm, and
internal events are saved in the internal memory as event log.
Setup Function The setup file needed for EQ100-E can be created using EQ-Manager
included in the accessory software.
The setup file can be written in EQ100-E from EQ-Manager, a web
screen, or the SD card in which the setup file is stored.
Synchronization with
EQ Server
EQ100-E synchronizes time with the EQ Server (PC used as a server).
Synchronization with
SNTP Server
EQ100-E synchronizes time with the SNTP server.
Network Connection LAN connection port: The connectable functions/devices are as follows:
A host system (EQ server, EQ-Manager, SMTP server, SNTP server,
FTP server, and FTP client), a personal computer (web browser), and
measurement device
Sub-LAN connection port: Connectable functions/devices are as
follows: Measurement devices, personal computers (web browser)
Web Function (Japanese, English, and
Chinese languages are supported)
You can confirm operating condition, operate the EQ100-E, view simple
graphs, and perform maintenance through a web browser on a
computer connected to the LAN or sub-LAN connection port. The
operation channel cannot be displayed as a graph.
Taking Out Internal Data File The following four methods are available:
(1) Collecting by EQ Server The EQ server collects the collected data and event logs stored in the
EQ100-E internal memory via the network.
(2) Operations on Web
UI Screen
The collected data or event logs stored in the EQ100-E internal memory
is downloaded to the personal computer by operations on the Web UI
(3) SD Card Output Any of the following operations outputs the collected data and log files
stored in the EQ100-E internal memory to an SD card.
• Pressing the SD card save button on the EQ100-E front side
• Web UI operations: SD card data output operations
If the SD card output setting is configured as "Yes" by EQ-Manager, the
collected data stored in the EQ100-E internal memory is saved on an
SD card once a day.
(4) FTP Transfer FTP server and FTP client functions are available.
• FTP server function: Acquires the collected data files stored in the
EQ100-E internal memory via an FTP client and the collected data on
an SD card attached to EQ100-E or an event log.
• FTP client function: Sends collected data files stored in the EQ100-E
internal memory to the FTP server from EQ100-E.
Function Alarm is set off when collected data exceeds the upper or lower limit.
Output to a general-purpose output terminal is available as well.
Email Notification Function: Monitoring Alarm Email
Log to Internal Memory Monitoring alarm occurrence is saved into the internal memory.
The event log can be checked on the Web UI screen and outputted as
an event log file.
Status Indication The monitoring alarm indicator is turned ON.
Device Alarm
Function Detects a device failure, setup/status failure, device failure,
communication failure, or monitoring process failure.
Email Notification Function: Device alarm notification email
Status Indication Lighting, blinking, blinking in long cycles, temporary lighting of the
device alarm indicator lamp
Log to Internal Memory An occurred device alarm is saved into the internal memory. It can be
outputted as an event log file.
Contact Output Function An alarm can be outputted through the general-purpose output terminal
when the monitoring condition is met.
Function • Monitoring alarm notification email: Sent upon a monitoring alarm
• Device alarm notification email: Sent upon an occurrence of a device
failure or an abnormality of setup/status, device, communications, or
monitoring process of EQ100-E.
• Periodic alarm: An e-mail with the main text is written by the user is
sent at a specified time.
• Test email: Sent by Web UI operations to check the email notification
settings or the state of communications with the SMTP server.
Note: The SMTP function with email transmission authentication
• POP before SMTP
• POP before SMTP(APOP)
Communication Test Communications with connected measurement devices are
continuously performed to check stability of the communications with
measurement devices. Collected data are not saved.
Clock Setting The time is configured for the built-in clock of the EQ100-E.
The general-purpose output terminals of the main unit are operated ON
or OFF.
FTP Test Transfer FTP transfer from the EQ100 to the FTP server is tested.
Firmware Update The firmware of the EQ100-E is updated. The firmware can be updated
by any of the following methods:
• By Web UI operations, the firmware is transferred from the PC to
EQ100-E to update.
• By inserting an SD card containing the firmware to EQ100-E to update
the firmware.

*1. The maximum number of measurement channels of EQ100-E is 500, including all sensors (measurement devices) and
      operation channels.
*2. One slave device of wireless sensor is calculated as one device regardless of the number of master devices connected
      with LAN and the number of connected relay devices.
*3. No. of connected KM-N1-FLK devices = No. of measurement circuits (No. of the measurement circuits set on the power
      sensor main unit), No. of connected KM1 devices = No. of units (No. of master and slave devices)
*4. For RS-485 connection, either CompWay/F or ModbusRTU can be selected for each communication port.
