MODBUS slave emulator in Serial Port Monitor
MODBUS Data Loggers for MODBUS RTU, TCP, ASCII
MODBUS RTU: This protocol uses a serial communication interface and is widely used for connecting devices in field environments. It is based on binary data representation and utilizes a master-slave architecture.
MODBUS TCP: This protocol operates over Ethernet and is used for communication between devices on a TCP/IP network. It allows for faster data exchange and is commonly used in industrial applications.
MODBUS RTU Data Logging
This logger can poll and read data from MODBUS RTU and MODBUS ASCII devices using the corresponding plugin. It can work fully automatically in the 24x7 mode. Read our tutorials!
MODBUS TCP Data Logging
This logger can poll and read data from MODBUS TCP devices using the MODBUS/TCP plugin. It was designed to operate in the 24x7 mode. Both loggers can export data to databases or log to a file, and many other formats.
MODBUS debug and emulation
MODBUS slave emulator in Serial Port Monitor
This convenient software utility has a plugin that can work as a MODBUS RTU/ASCII master and slave. Therefore, you may poll and emulate MODBUS devices.
Other utilities with MODBUS support
MODBUS Gateway
It is a software real-time bidirectional MODBUS TCP - MODBUS RTU protocol converter. It enables you to connect MODBUS TCP devices to systems or PLCs that can only work with MODBUS RTU. Protocol conversion is executed in real-time.
Datatag Link
You can connect a MODBUS device to SQL, MQTT, OPC, and send data in both directions. The program acts as a MODBUS master.
