The simplicity of these messages allows the basic 16-bit Modbus RTU register structure to be used to pack in floating points, tables, ASCII characters, and other data. Modbus RTU messages are a simple 16-bit structure with a Cyclic-Redundant Checksum (CRC). Widely used in building management systems and in industrial automation systems to connect electronic devices, Modbus RTU is a popular protocol due to its ease of use and reliability. As an open standard protocol, manufacturers can build it into equipment without paying royalties. Modbus RTU is a version of the Modbus open serial protocol. So, let's dive into the Modbus RTU protocol.

We're experts and it's important to us that you know how to get the most out of your network monitoring system. Here, at DPS, we've provided many different Modbus monitoring solutions throughout our 30+ years in the market. This way, you'll have an efficient remote monitoring system. If in your SCADA system, you have Modbus protocol connecting your remote equipment to your Remote Terminal Units (RTUs) and to your master station, then it's critical that you understand how this protocol works. In Supervisory Control and Data Acquisition ( SCADA) systems, Modbus is commonly used to communicate data and control commands. Modbus-enabled devices are very common among many manufacturers throughout many different industries.
No wonder, this protocol's unconnected messages, and simple request-response communication structure are now considered unusual among today's technologies. Modbus is, in fact, almost as old as the first PLC (Programmable Logic Controller), the Modicon 084. The Modbus protocol is, what many calls, the grandfather of industrial networking.
