Traditionally, combustion control panels have been living in a hard-wired world. More often than not, the status of a burner system is communicated by indicator lights on a Flame Safeguard (FSG) terminal.
With the increased use of Programmable Logic Controllers (PLCs) controlling all aspects of a combustion system, customers are demanding more information from the FSG, as many operators manage their systems from a centralized control room.
While some customers have traded in their indicator lights for relays with dry contacts that feed back into their PLC, other customers are looking to simplify the communication between the FSG and PLC, while extracting more information on the operation of their burner system.
Here, we will go over some examples of technologies that are available today, and how you can get the information you need to where you need it.
More and more people are using Modbus to get data from their instruments and controllers back into their control systems for reporting, alarming and troubleshooting.
And while I can’t be there to help you set up your Modbus master, I can give you 13 rules and some general practice advice for communicating to any Modbus RTU device.
