MC0307 Modbus to PA Embedded Core Module Working Principle:
MC0307 Modbus to PA embedded module is only support one-to-one Modbus and Profibus PA communication protocol conversion module. As a PA device, you can communicate with the Modbus device.Through the configuration, the interaction between Modbus device data and PA device data can be realized.

MC0307 Modbus to PA embedded module contains 1 physical block, 1 transformation block, 16 functional blocks, and only supports 1 Modbus slave station.
Among them, the transformation block mainly includes 6 analog input, 2 analog output, 4 discrete input and 4 discrete output, a total of 16 circular parameters, 10 floating point, 1032-bit integer, 1016-bit integer, 108-bitinteger and 232-byte strings, a total of 42 non-circular parameters.
The main function of a transform block is to interact with Modbus devices.
