ModGate-Plus ModBus Converter LAN/WLAN RS232, RS422, RS485

Benefits of the ModGate-Plus Ethernet/WLAN to ModBus Converters

• Connects 1, 2, 4 or 8 ModBus serial lines to network running TCP/IP.
• Automatically adjusts as Master or Slave.
• Robust metal case.

ModGate-Plus ModBus Converter LAN/WLAN RS232, RS422, RS485

The ModGate-Plus are easy to use gateways from ModBus/TCP on Ethernet or WLAN to ModBus/RTU or ModBus/ASCII on the serial ports. ModGate-Plus connect one, two, four or eight ModBus serial lines to a network running TCP/IP. Metal case, wide temperature range and flexible DC power supply classify the ModGate-Plus as industrial-strength devices. They are based on a state-of-the-art RISC processor, to provide cost-effective design and low power consumption.

Using TCP/IP the ModGate-Plus operate without limitations on distance or OS platform, the gateways are usable via Internet and VPN connections. The serial port is configured for ModBus/ASCII or ModBus/RTU and physically set to RS232, RS422 or RS485 operation. The messages received on the network are sent to the serial line, messages from the serial port are sent via network. ModGate-Plus automatically adjusts as Master or Slave on the serial port. ModBus Master Multiplexing is implemented as an extension to the standard. Several masters connect to ModGate-Plus by ModBus/TCP, slaves on serial lines may answer requests from multiple masters.

The configuration of ModGate-Plus is done via browser. The user interface is based on Web 2.0 to provide an easy handling of the options. UPnP provides a simple and standard way to find the gateway in the network.

ModGate-Plus devices can be ordered with an embedded module for WLAN 802.11b/g/n (option 6689 or 6690). Plus the ModGate-Plus may be ordered as POE (Power over Ethernet) device, with additional power supply via Power-over-Ethernet 802.3af (Class 0).
