The communication drivers for Modbus TCP and RTU/ASCII protocols are implemented as Modbus TCP and Modbus Serial devices. They provide high-performance polling, support a variety of data encoding formats, and they can operate in a shared channel mode.
Key Features
- Communication with Modbus TCP, RTU over TCP, RTU/ASCII as master or slave
- Data types: Boolean, Byte, Byte Array, Word, Word Array, Int, Int Array, DWord, DWord Array, DInt (32-bit signed integer), DInt Array, Float, Float Array, Double, Double Array, QWord, QWord Array, Long, Long Array, String
- Data areas: Internal Registers, Holding Registers, Input Coils, Output Coils
- Byte, word and dword order swapping
