MODBUS POLL LOGGING PC
Some customers would like the ability to view live data, alarms, and charts on the plant floor without a PC or be able to directly control the operation of the Modbus data loggers. We offer Novus Airgate devices from Novus that provide a range of up to 3000 feet using an industrial radio or a Cellular model that provides a virtually unlimited range.

This allows the system to be distributed over longer distances, between different buildings in a plant, on a campus or even across states.Ī relatively new option is Modbus via a wireless network. Several of the data loggers also provide support for Modbus over a TCP/IP network connection. This is a 2-wire serial interface that allows communication between devices up to 4000 feet apart.

If your application requires control or alarm outputs, we can also supply digital, relay, voltage or current output modules to interface with other devices.Ī key feature of the Modbus protocol is that it allows communications between devices using a number of different physical interconnections. It will also serve as the central repository for all of the data and provide the alarming functions if necessary.ĬAS offers a variety of Modbus I/O modules to measure temperature, voltage, current, digital state or pulse signals. This logger will manage the communications between the other Modbus devices, either reading or writing data. Typically, one logger will be designated as the system master. The Modbus communications standard provides a way to seamlessly tie all of these devices together to build a system that is customized to fit your exact needs. If you cannot find the Modbus data loggers or system that meets your I/O requirements or if you need a distributed system to monitor multiple points spread across a factory floor or several buildings, data logging systems can be configured using Modbus based devices.
