Elpro's industrial 802.11 products now provide device server functionality with Modbus Master capability for both Ethernet Modbus TCP and serial Modbus RTU. This new capability provides significant benefits in scada applications that require a flexible I/O data transfer capability. Some of the key onboard features now enable the model 240U-E to act as a Modbus TCP client or server, act as a Modbus RTU serial master and also communicate Modbus TCP Ethernet to RTU Gateway.
The new Device Server feature allows users to:
* Connect to Modbus TCP and/or Modbus RTU slave devices without the need for a standalone master.
* Convert message between Modbus TCP and Modbus RTU.
* Simultaneously manage independent connections to both Modbus TCP and Modbus RTU devices at the same 802.11 unit.
Elpro's industrial 802.11 family comprises the 240U-E WiFi unit, 905U-E 900 MHz FH unit (for America), and 805 U-E 869 MHz unit (for Europe and southern Africa).
These units are designed for high-speed 802.11 wireless data networking in heavy industrial environments, providing Ethernet and serial connectivity simultaneously as a multiport Device Server, controlling communications to multiple devices.
Like all Elpro products, the 802.11 family carries an exclusive lifetime warranty.
