Supported Features

• Standard registers:

  • Coils: Available as a model output, a model input (controlled by the master) or both

  • Discrete inputs: Available as a model output

  • Input registers: Available as a model output. The supported data types are UINT16, INT16, UINT32, INT32 and FLOAT32.

  • Holding registers: Available as a model output, a model input (controlled by the master) or both. The supported data types are UINT16, INT16, UINT32, INT32 and FLOAT32.

• TCP and RTU modes

• Allows multiple slaves instantiation

• Configurable TCP port when operating over TCP mode

• Configurable serial port parameters when operating over RTU mode

• Supports reconnection with master device(s) if a connection is lost

• TCP mode supports connecting multiple masters to the same slave

• TCP mode supports having multiple slaves with the same IP address and TCP port combination; in this scenario, the slave ID is used as the differentiator

Limitations

• Modbus ASCII is not supported

• An OP3310 RS-232/422/485 PCIe serial card is needed in case it is required to communicate with multiple slaves on the same physical bus in RTU mode
