6. MDC Configuration (config.csv)
6.1. Exporting/Importing the Config.csv File
The MDC function in the MDCL-705i module 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, and change the status of a channel by writing command to the register
assigned for the channel in the MDCL module.
Modbus RTU polling definition in config.csv is used to define Modbus RTU commands for reading data
from the slave devices. The Comma Separated Values (CSV) files can be viewed and edited in spreadsheet
applications like Microsoft Excel, or in any text editor, in which the comma character (,) typically separates
each field of text.
The file name
config.csv
cannot be changed, and the name and order of parameters in each line for a
polling definition cannot be changed, too. To avoid errors caused by manual editing, you can export the
config.csv file from
Modbus
page and modify it to meet your requirements.
