The radio allows the user to collect I/O without a remotely located PLC
or I/O data concentrator. The bused I/O is made accessible to the
network using the Modbus protocol. It can easily be integrated into new
or existing PLC, SCADA, or DCS systems, says the vendor. A multiple
master function has been added to the 900 MHz TWE radio family, which
can create redundancy and wireless failover connections if a master or
host radio is not accessible. Phoenix Contact Inc.www.phoenixcontact.com800.322.3225
