Omron has solved a tough data gathering issue in industrial automation with its WT30 wireless serial communications system. The company says it eliminates barriers to communicating with moving equipment, retrofitting networking on running devices and evading obstacles where wiring is impractical. It consists of one master and multiple slave I/O stations with expansion capability for up to 64 slaves (more than 1,000 I/O). The wireless serial master collects on/off data and provides an RS-232C (CompoWay/F) interface to a personal computer or PLC. The communication distance between a WT30 master and I/O slave without using a repeater is 60 meters minimum indoors and 300 meters outdoors.
