Modbus to PA Built-in Module installation

M0307 has three Φ3 positioning holes. User can use 3 hexagonal prism with height 11mm to fix it to user board.

 

 

Modbus to PA Built-in Module Working principle

M0307 Modbus to PA built-in module is only one to one conversion module between Modbus and Profibus PA protocol. As a PA device, it can communicate with the Modbus device. Through configuration, it can achieve the interaction between Modbus device data and PA device data.

System connection chart

 

M0307 Modbus to PA built-in module contains 1 physical blocks, 1 transducer blocks, 16 function blocks, and

only 1 Modbus slave station.

The transducer block includes 4 analog input channels, 4 analog output channels, 4 discrete input channels

and 4 discrete output channels, totally 16 cyclic parameters. It also contains 10 floats, ten 32 bit integer, ten 16 bit

integer, ten 8 bit integer and two 32 byte string, totally 42 acyclic parameters.

The main function of the transducer block is to interact with the Modbus device.

 

 

Modbus to PA Built-in Module Working mode

M0307 can switch the two modes of operation by using the special function dial switch S2: configuration

mode and normal mode. ON is for configuration mode, and OFF is for normal mode.

Modbus to PA Built-in Module FAQ

Q: How do I configure cyclic input and output parameter?

A: M0307 Modbus to PA Module includes analog input, analog output, discrete input and discrete output parameters. The number of parameters are fixed as four, so this chapter will introduce how these parameters and Modbus slave station associates. These 4 parameters all have read and write, data type, register address, function code and other attributes, which can be configured through the Modbus configuration tool.

 

Q: Can you provided OEM service?

A: Yes, we can, such as communication board, we can also provided fieldbus development toolkit.
