Introduction

MDC -211 -433 is a Modbus data concentrator developed by ICP DAS, with Ethernet, 433MHz Wireless, RS - 232 and RS -485 communication interfaces, can link the Modbus RTU devices to the Ethernet network. MDC -211 -433 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 -433 from Ethernet to access the data of multiple Modbus RTU devices at once. Through MDC -211 -433's Modbus data centralized management function, as well as the Ethernet network convenient link and the communication ability, it can quickly establish a stable remote monitoring system, simplify the complexity during the process of data acquisition operation, reduces the Ethernet network traffic load, and enhances the system efficiency.

MDC-211-WF

Wi-Fi Modbus Data Concentrator

Features:

• Compatible with IEEE 802.11 a/b/g standards
• Support Infrastructure and Limit -AP mode 
• Support WEP, WPA and WPA2 encryption mechanism 
• Support the Modbus TCP/RTU protocol 
• Compatible with WF -2000 I/O modules 
• Support Ethernet, RS -232/485 and Wi -Fi interfaces

Introduction

MDC -211 -WF is a Modbus Data Concentrator used to access data from disparate Modbus slave devices with a contiguous Modbus address table ranged by the concentrator. Up to 240 Modbus commands can be performed to read data from Modbus slave devices via Wi -Fi/RS -232/485, and up to 6 Modbus/TCP masters are allowed to get the polled data via the Ethernet. The Modbus/TCP masters directly read/write the data in the MDC -211 -WF instead of polling each Modbus slave device one by one. This way not only makes the data on the Wi -Fi/RS -232/485 sharable to multiple Modbus/ TCP master but also shorten the time to read/write data from/to multiple Modbus/RTU slave devices.

MDC-211-ZT

ZigBee Modbus Data Concentrator

Features:

• Fully Compliant with 2.4 G (IEEE802.15.4/ ZigBee Specifications)
• Upgrade ZigBee I/O modules with Ethernet communication ability
• Support the Modbus TCP/RTU protocol
• Support the MQTT v3.1 Client protocol
• Support I/O data logger (MicroSD) function
• Data pool for up to 9600 registers
• Modbus polling commands for up to 240 definitions
• Speed up the time for reading from ZT -2000 series modules
  Support ZigBee, Ethernet and RS 232/485 interfaces

Introduction

MDC -211 -ZT is a Modbus Data Concentrator used to centrally manage decentralized I/O data via the ZigBee wireless mesh network. It access data from disparate Modbus slave devices with a contiguous Modbus address table ranged by the concentrator. Up to 240 Modbus commands can be performed to read data from Modbus slave devices via ZigBee/RS -232/RS - 485, and up to 8 Modbus/TCP masters are allowed to get the polled data via the Ethernet. This way not only makes the data on the ZigBee/RS -232/RS -485 sharable to multiple Modbus/TCP master but also reduce the flow of ZigBee/Ethernet traffic load to improve the system performance. It is the best solution for users quickly establishing a remote monitoring system.
