1. Introduction
The MDCL-705i module is a Modbus Data Concentrator with data logger function, which can
concentrate data from several Modbus RTU slave devices through standard RS-485 interfaces, and
allows Modbus TCP masters to read/write data via Ethernet/LAN. The Modbus master can use one
Modbus command to get all data with the same type from various Modbus RTU slave devices via the
concentrator. In other words, through the help of a MDCL module, the Modbus RTU slave devices
can be accessed over Ethernet with better read and write performance.
Up to 250 Modbus RTU commands to read data from Modbus RTU slave devices can be performed in
the MDCL module and up to 8 Modbus TCP masters can connect the module to get the polled data.
The support for data logger allows users to pick-up up to 120 parameters for long-term logging.
Users can download data log files (CSV file) from the web interface or transfer the files to FTP server
for advanced analysis.
Features
HTML5 web-based user interface
HTML5 is the latest version of the HTML markup language. It is supported by most current
browsers including Mozilla Firefox, Apple Safari, Google Chrome and so on.
For the reason, the Web-based user interface of the MDCL-705i is accessible from a wide variety
of devices anywhere. Users can configure the module and monitor connection status of each
polling definition through their smart phones, tablets or desktops without a line of code.
Great Capability of Shared Memory
The MDCL-705i module can perform up to 250 polling definitions. And the internal shared
memory has four tables to store the polled AI, AO, DI and DO data. Each table can store up to
9600 registers.
Editing CSV files to Ease Hard Work of Managing Definitions and Logs
Built-in definition validation
Automatic data transfer via FTP (ongoing)
Editing and checking a lot of polling definitions or log channel settings is hard work and is easy
to make mistakes. Using CSV files to manage so many configurations with Excel makes it easy;
the CSV files can be imported or exported from the module via a simple mouse-click action.
One of the polling definitions may not be executed due to invalid parameters is given in the
imported config.csv file. The MDCL module provides the function of validating and displaying
invalid parameters with line information in config.csv file on its web interface.
Invalid parameters
The MDCL-705i can upload the data log files to an FTP server based on user’s daily task
schedule. Log files from different modules will be transferred to different folders on an FTP
server; the name of every log file will contain its creation time and date.
Supports NTP client
Support for Modbus TCP master and Modus RTU master
Support Data Logging
The MDCL-705i can be accessed by Modbus TCP Master and Modus RTU Master. Changing the
mode for a COM port from Master to Slave allows a connected Modus RTU Master to
read/write data from/to the Modbus RTU slave devices on the other COM ports.
NTP stands for Network Time Protocol and it is a networking protocol for clock synchronization
between computer systems. It is used to synchronize computer clock times in a network.
In order to ensure the data logged with correct timestamps, an NTP server can be set by IP
address or name on the MDCL-705i to synchronize the date and time information based on the
specified schedule.
Up to 120 parameters per record with ratio and offset conversion functions.
Selectable data logging time interval from 5 seconds to 60 minutes.
Built-in 32GB microSD card.
Log file time period varies from 1 to 24 hours.
Downloading log files via the web interface of the MDCL-705i.
Timestamp alignment
In general, we have to synchronize log data from multiple sensor signals measured in different parts.
They are likely to have slightly different sampling rates and clock times that require an offset. It is a
hard and complex task to calculate and align the timestamp of log data from different instruments or
locations. MDCL provides a very clever mechanism that allows users to quickly align the time and
perform more sophisticated analyses.
1. Support NTP time synchronization.
MDCL has a built-in Real Time Clock, and records data with timestamps. To increase the accuracy
of system time in the RTC, MDCL can be configured to execute automatic time correction from
the NTP server on the network, or manually set to synchronize its clock with the time of your
local PC or an NTP server.
2. Generate filename with creation date and time.
MDCL provides a consistent name format for log files that allows you to identify them. The file
name begins with a "T_" prefix followed by the creation date and time in MMDDHH format.
3. Shift log intervals based on clock times.
The log interval in MDCL is ranged from 5 seconds to 6 hours, it records data every interval
starting on the hour (00:00) where intervals are less than or equal to 1 hour; and beginning at
midnight where intervals are more than 1 hour.
Besides the first entry, the data will be recorded at 00:00, 15:00, 30:00 and 45:00 every hour
when the Logging Rate is set to a 15-minute interval.
If three MDCL modules are enabled to log data with different starting time, and the same Logging
Rate setting of 15 minutes is applied, the entries will seem to be logged at the same time point,
although they are recorded on different MDCL.

4. Create log file on the hour.
The time interval for creating a new log file in MDCL is synchronized to 24 hour time. Depending
on the setting of maximum logging period, a new log file would be created at every interval on
the hour starting at midnight (00:00:00).
For instance, setting the maximum logging period to 6 hour means that new files would be create
to record data at 00:00:00, 06:00:00, 12:00:00, 18:00:00, and repeat that schedule.
If three MDCL modules are enabled to log data with different starting time and the same
Maximum Logging Period of 6 hour is applied, the log files will seem to start logging at the same
time among these devices, except the first time.
In conclusion, when you retrieve a large amount of files from multiple MDCL modules with the same
Logging Rate and Maximum Logging Period settings, you can easily complete the data synchroniza-
tion by modifying the prefix “T_”in the file name based on where these files were collected from.
