MAXIFLEX Ethernet NIM Model M1591B Ethernet TCP/IP Programmable Modbus Network Interface Module DATASHEET FEATURES • Integral Ethernet Port (10/100BaseT) Built in Modbus/TCP® Master and Slave protocols. Programmable for custom data mapping Easy configuration using free software utility. Integrates Maxiflex into any Modbus/TCP network. Communicate with 3rd Party Modbus/TCP Slave Devices Create additional/redundant Modbus/TCP connections to your SCADA/DCS system The Maxiflex M1591B Ethernet Modbus Network Interface Module (Ethernet NIM) is designed specifically to allow access from Modbus and Modbus/TCP Master or Slave devices to a Maxiflex system. The Ethernet NIM comes equipped with the Modbus over Ethernet and Modbus/TCP protocols (selectable in the configuration), for a wide range of applications. In addition, the Ethernet NIM supports the development of custom programs in the EziFORTH programming language. This allows extremely flexible data mapping and data format conversion and scaling between the Maxiflex system and the Modbus Device. All data is interchanged between the SCADA, DCS or PLC and the Maxiflex system CPU through a 4000 register Data Interchange Table in the Ethernet NIM. All system configuration data and dynamic data can be read and written through this convenient table interface. Using the supplied Omniset configuration utility, advanced polling schemes may be easily set up without the need for programming. All polling and communications processing is performed in the module, unloading the Maxiflex CPU module for the more important system tasks such as control and other SCADA communications. Communicate with any Modbus Master or Slave device over Ethernet. Communicate over wide area networks, integrating remote RTU’s into local systems. Exchange data over Ethernet with third party devices equipped with Modbus communications ports. Communicate with more than one SCADA system over independent Ethernet networks from a single Ethernet network Create redundant Ethernet communications paths to your SCADA system from a single Maxiflex system.
