MODBUS OVERVIEW
Modbus for production monitoring.
Modbus is a long-established industrial communications protocol that can make selected machine or process values available to monitoring systems.
Where it can fit
Modbus TCP and Modbus RTU are found across many industrial devices. They can be useful when the required production values are available and the site permits the connection.
Meaning is more important than register count
Knowing a register address is not enough. Teams need to understand the engineering meaning, data type, scaling and production context of the value.
Assess each application
Network design, serial settings, polling requirements and the device’s own limitations differ by installation. These details should be validated as part of implementation rather than assumed from the protocol name alone.
COMMON QUESTIONS
Frequently asked questions.
Is Modbus the same as OPC UA?
No. They are different industrial communication technologies with different capabilities and data models.
Can Modbus be used on older equipment?
Sometimes. It depends on whether the controller or device exposes the required information through Modbus.
