The following table covers the basic differences with respect to its applications in Solar Equipments.
RS485 MODBUS RTU SERIAL
Modbus RTU RS485: Remote Terminal Unit (RTU) Modbus over a serial RS485 connection Modbus TCP: Modbus over an Ethernet connection.
Our Modbus gateways are versatile enough to work in a variety of industrial environments, with the free software included with each device that is easy to configure. Modbus RS-485 & Modbus TCP/IP interfaces are widely used in the industry for connecting & monitoring various equipment. Each converter available in our offer is easy to mount on DIN rail (standard or with mounting brackets), immunity to electromagnetic interference and the possibility of installation in outdoor boxes and environments with a wide operating temperature range from -40☌ to 85☌.
We have prepared various industrial Modbus gateways for you, depending on the type of installation, the operating temperature range and the number of RS-232 and RS-485 ports on the Modbus RTU/ASCII side. Due to its versatility, the Modbus protocol is one of the most popular communication protocols in the industry. Modbus is used in industrial automation, among others for communication with control systems, air conditioning, heating, BMS and many others. This category includes Modbus gateways communicating in Modbus RTU/ASCII standard with RS-232 or RS-485 interface and Modbus TCP with Ethernet interface.
