Yokogawa Data Acquisition Wireless Network (DAWN) Mesh IO Radios M1115NL

Yokogawa's Network Solutions Group is pleased to present a quick overview of the DAWN M1115NL Wireless IO Radio. The M1115NL is an effective way to acquire sensor data for SCADA, DCS, HMI, PLC, and other control or data acquisition systems. IO can be directly wired the M1115NL as it supports 8 digital input/outputs (individually settable), 4 analog inputs (DC mA or DCV), and 2 analog outputs (mA). Four of the digital inputs can also be configured as pulse inputs with support to 50KHz. The M1115NL supports Modbus TCP (client and server) over Ethernet as well as Modbus RTU Master over RS485 for connecting to remote instruments or upper level systems. The M1115NL features web based configuration via a browser. The M1115NL supports 900MHz Frequency Hopping Spread Spectrum operation at 1W which gives it secure, powerful, noise resistant communications at up to 20 miles line of sight. The M1115NL is also a mesh radio that can operate as a repeater where radios on the same network can automatically re-route through each other to make it back to the host radio in case of interference or signal quality issues.

Wireless I/O

Data acquisition measurements (voltage, analog voltage, analog current, and themocouples) across large physical distances can prove challenging. Wireless I/O networking dramatically reduces thermocouple wire and CAT5 cabling, enabling remote monitoring.
