EC: WI-MOD-E-G Wireless Industrial Ethernet Modem
Network integration - Wireless products: The WI-MOD-E-G wireless industrial Ethernet modem from Weidmuller provides wireless Ethernet communications in process/automation applications connecting to PLCs, DCS/ SCADA, data loggers, or field instruments with an RS232/485 or Ethernet port/interface. This is a Control Engineering 2012 Engineers’ Choice honorable mention.
As industry embraces wireless connectivity as a primary connection method on networks and bus systems, Weidmuller’s new industrial Ethernet device (2.4 Ghz, Wi-Fi), created with the demands of the industrial marketplace in mind, can be easily dropped into any existing network. It is the ideal solution for wireless connections in process/automation applications connecting to PLCs, DCS/ SCADA, data loggers, or field instruments with an RS232/485 or Ethernet port/ interface. Built around the 802.11 b/g standard, the new WI-MOD-E-G wireless Ethernet modem has a throughput speed of up to 108 Mbps perfect for supporting vision and video applications. It features 400 mW of transmit power (up to 10 times that of consumer/commercial grade wireless devices), so it can broadcast much more information over greater distances or through obstructions.
The new modem can operate as a router/bridge, access point/client, and serial server (RS232/485). It has the ability to serve as a Wi-Fi device and handle serial communications simultaneously, over a very intuitive interface unique in the market today. By attaching an I/O expansion unit to the device, a user can send or receive up to 16 digital or 8 analog signals and Ethernet (Wi-Fi) at the same time. This modem readily provides stand-alone Modbus Master-Slave functionality within the network, and with other modules in the system with DHCP automatic IP addressing capability. Unit and data security is ensured with full WEP and WPA2 PSK (802.11i military standard) encryption, MAC address filtering, IP filtering, password login, and white/black list authentication. Weidmuller’s new modem addresses the potential wireless Ethernet device weaknesses that have existed in industrial automation. With increased broadcast power; the ability to move Ethernet and serial signals simultaneously; Class 1, Division 2 hazardous area approvals; and industry-leading throughput of 108 Mbps, it is a strong and capable solution to wireless Ethernet communications.
