MDC-211-ZT User Manual Warranty All products manufactured by ICP DAS are under warranty regarding defective materials for a period of one year, beginning from the date of delivery to the original purchaser. Warning ICP DAS assumes no liability for any damage resulting from the use of this product.
Wireless, RS-232 and RS-485 communication interfaces, can link the Modbus RTU devices to the Ethernet network. MDC-211-ZT can read the data of Modbus RTU device according to the user-defined command table, and integrate the data of different Modbus RTU devices into the format of the continuous address so that the remote monitor host can connect to MDC-211-ZT from Ethernet to access the data of multiple Modbus RTU devices at once.
Support Modbus TCP/RTU Slave The ZigBee, RS-485, RS-232 or Ethernet on the MDC-211-ZT can be set as Modbus Slave, so the control host can access multiple Modbus RTU devices via MDC-211-ZT at once.

Serial port communication parameters and the Modbus RTU commands that settings can also be edited in a *.csv file and import into the MDC-211-ZT from the Web UI, and then start to monitor the data of the remote Modbus RTU devices.
Antenna LED Indicator MicroSD Card Ethernet Port The MDC-211-ZT is equipped with a RJ45 port for Ethernet LAN connection. When 100BASE‐TX is operating, the 10/100M LED is lit orange. When 10BASE‐T is operating or the machine is not connected to the network, it is turned off. When an Ethernet link is detected and an Ethernet packet is received, the Link/Act LED is lit green.

Modbus Internal Register Address of MDC-211-ZT When MDC-211-ZT as Modbus Slave, the external controller can indirectly read the data of the Modbus RTU devices, for its corresponding Modbus Register information, refer to "2.6.2 Inquire Modbus Inner- register address of the corresponding relationship".
MDC-211-ZT Web interface. This section describes how to check the Modbus command status, real-time monitor the I/O channel status of Modbus RTU device, and inquire the relationship for the Modbus RTU device I/O and the MDC-211-ZT Internal Register address. 2.6.1. Check polling status of Modbus command Click "I/O Information"...

Figure 2.13. The "Remote" item in the mapping table represents the Register address of the Modbus RTU device; the "MDC-211-ZT" item represents the corresponding Internal Register address. The users can access Internal Register address in the “MDC-211-ZT" item via the Modbus protocol to control the entity Modbus RTU device.
2.6.3. Testing I/O Channel Status of Modbus RTU Device MDC-211-ZT can real-time control the I/O channel of Modbus RTU devices via the standard Modbus protocol, and also provide Web UI to real-time control the Modbus I/O channel status. As Figure 2.14, users only need to click "I/O Information" and select the Modbus RTU device want to control, the Web UI will display the pre-set Modbus command and real-time display that Modbus device I/O channel status.
3. Export and Import the System Settings The user can set up MDC-211-ZT via the Web UI, and also can export the configuration to a *.csv file in the local computer for backup.
