Monitoring Environmental Conditions
A Modbus-based, wireless I/O network that monitors sensor data at each location, in addition to providing hard-wire control outputs based on sensor data met the customer’s needs. Using Banner’s Modbus MultiHop Wireless I/O system allows the customer to monitor each environmental variable independently. This information is transmitted through the wireless network to a local controller and then on to a central control room where additional networks of environmental and/or process data can be monitored simultaneously.
The MultiHop network consists of 25 wireless devices including sensors, controllers, and I/O devices. The Modbus MultiHop Master Radio collects and routes data from all the repeater and slave radios, communicates via Modbus RTU which is a universally accepted protocol for most HMI, PLC, or SCADA systems. The repeater and slave radios provides a junction for Modbus slave devices and has a built-in analog I/O, provides a location from its address within the Modbus MultiHop radio network, and extends the range of the network by providing a repeater station to extend distances and get around radio signal obstacles. The MultiHop network also includes the M12FTHQ3 Temperature and Humidity Sensor and CL50 Indicator Lights with Audible Alarm.
Create point-to-multi point networks that distribute I/O over large areas. Input and output types include discrete (dry contact, PNP/NPN), analog (0 to 10 V dc, 0 to 20 mA), temperature (thermocouple and RTD), and pulse counter.
Sure Cross® Temperature and Humidity Sensors work in a variety of environments to provide temperature and humidity measurements. Used with Sure Cross Wireless Radios, these sensors make it easy to monitor environmental conditions without costly wiring runs to monitoring points.
