Taipei, Taiwan, 2010/07/28 - Korenix brings innovative applications to the industrial networking sector by releasing Comtrol’s latest Modbus Server firmware, which provides advanced connectivity for OPC servers and applications that require Modbus/RTU communication.
Through standard Ethernet TCP/IP, per each serial port it is possible to connect up to six master applications with different IP addresses by Modbus Server. This unique software accompanying with DeviceMaster series not only greatly enhance system maintenance capabilities, but also provide Modbus/RTU functionality required for building automation, factory, warehouse, and transportation applications.
Modbus/RTU multi-connections over Ethernet TCP/IP:
Without using standard Modbus gateway for Modbus/RTU to Modbus/TCP conversion, Modbus Server can be easily uploaded on most of your DeviceMaster devices to take advantage of Ethernet multi-connectivity features for Modbus RTU communication. It supports Modbus/RTU over Ethernet TCP/IP connections to the corresponding serial port via intelligent Modbus message routing for some specific applications.
The new firmware multi-connection functionality greatly benefits users:
• Supports up to six Ethernet TCP/IP connections to each serial port
o One TCP/IP connection can be created with the “Connect To” connection method.
o The “Listen” connection method accepts up to five or six connections, depending if the “Connect to “ connection is active.
• Combined with a serial port redirector, can support up to six COM port connections to each serial port.
• Supports up to 255 Modbus slave devices per port. Both valid (1-247) and reserved (248-255) device ids are supported.
Distinguished Performance & Message Diagnostics
To maintain the high-quality of system communication, Modbus Server is designed for comprehensive device and port specific diagnostic web pages that display status, message response timing, timeout and error counts as well as overall message statistics. It provides:
• Modbus/RTU specific message handling:
o CRC verification of all messages received on the TCP/IP and serial interfaces.
o Timing out of responses from slave Modbus/RTU devices.
o Broadcast message handling on connected port only.
• System monitoring to ensure gateway operation:
o Gateway busy.
o Application message timeouts.
• Advanced diagnostics web pages:
o Modbus device specific statistics, response timing and status.
o Up to 255 devices per serial port can be monitored simultaneously.
o Serial port specific statistics and status. Serial port message logging.
