Modbus Solutions | Modbus Router Firmware Modbus Router is an innovative application providing highly versatile Modbus master-to-master and master-to-slave connectivity. The Modbus Router application was designed to provide highly flexible and robust connectivity for PLCs, SCADA systems, HMIs, OPC servers and applications that require a wide range of Modbus connectivity options. Modbus Router provides functionality such as: • • • • • • • • • • • Master-to-master connectivity via the Shared Memory sub-system Private Modbus serial bus support designed to restrict access to private Modbus devices Connectivity from serial Modbus masters to Modbus/TCP networks The ability to connect multiple types of Modbus masters to Modbus slave device(s) Convert from one form of Modbus, such as Modbus/TCP, to Modbus/RTU or Modbus/ASCII Provide connectivity from a serial Modbus master to a remote Modbus slave device Eliminate Modbus device ID conflicts and solve device ID configuration problems Enable Modbus security by blocking write messages in Read-Only Mode Device ID to Modbus/TCP slave via configurable IP address and TCP/IP port Modbus Network Bridging support While standard gateways provide limited connectivity for only directly connected Modbus slave devices, Modbus Router provides connectivity from multiple Modbus master types to both local and remote Modbus slaves. Simple or complex Modbus networks are easily created by combining multiple DeviceMaster UP chassis running Modbus Router and/or Modbus/TCP firmware. Modbus Router was designed to greatly enhance system maintenance capabilities. Included are comprehensive local and remote slave device and port specific diagnostic web pages that display status, message response timing, timeout and other error counts, and overall message statistics. A serial log is also included to provide message level diagnosis. The DeviceMaster UP configures in just minutes via embedded web pages. The included PortVision DX remote management and configuration software makes it a simple task to detect and manage every DeviceMaster UP on the network, facilitating firmware updates, troubleshooting, and remote administration. Modbus Router firmware supports the following controllers: • • • Modbus/TCP masters Modbus/RTU and Modbus/ASCII serial masters Modbus/RTU and Modbus/ASCII over Ethernet TCP/IP masters Modbus Router firmware supports the following devices: • • • Modbus/TCP slaves Modbus/RTU and Modbus/ASCII serial slaves With additional gateways, both remote Modbus serial slaves and raw/ ASCII devices Modbus Router firmware is recommended in installations that require: • • • • • • • • • Local (directly attached) Modbus master and/or slave connectivity All Modbus (No local raw/ASCII device connectivity) Automatic Modbus protocol translations (if needed) Connectivity to remote Modbus slave(s) and/or raw/ASCII device(s) Connecting single or multiple Modbus masters to the slave device(s) Master-to-master connectivity Isolation of serial Modbus slaves (via Private Serial Bus connectivity) Write protection of serial M

Supported Interfaces: Any PLC, SCADA System, HMI, OPC Server or Application that requires Modbus communications over Modbus/TCP, Com ports or Ethernet TCP/IP connections. Modbus Router highlights: • All masters can communicate to all public slave devices • Supports up to 96 Modbus/TCP connections (any combination of master and slave connections) • Modbus/TCP masters – accepts requests on up to eight TCP/IP ports. (includes standard port 502 and seven configurable ports.) • Modbus/TCP slaves – via configurable IP address and TCP/IP Port(s) • Supports up to six Ethernet TCP/IP connections per Ethernet...
