After the communication settings are completed, define the input physical point variables and output physical point variables in ConMaker, and participate in the logical operations in the configuration program. Start writing how to handle the read and written data in the program.
We have written four custom function blocks in the program, which are:
IN_ BOOL: Implementation function: Read the switch value (one WORD) transmitted by the PLC, decompose it into 16 switch values through one bit decomposition.

OUT_ BOOL: Implementation function: Combine 16 switch values into a PLC recognizable data (one WORD), and then output it.
IN_ REAL: Implementation function: Read the analog quantity transmitted by PLC. At this time, the format of the analog quantity read is different from that of the DCS system. It is necessary to first exchange the high and low bits of the data. In order to ensure that the analog quantity read has one decimal place, we multiply the analog quantity data by 10 in the PLC, divide it by 10 in the DCS, and then output it.
OUT_ REAL: To achieve the function, first multiply the data by 10, then exchange the high and low bits of the data, and then send the data to the PLC.

Define the 62 Global variable that need to be communicated in the resource, add the program that calls the function block to read and write data, COM_ PRG1 COM_ PRG2 COM_ PRG3 realizes the input and output of communication variables analog and digital inputs, and then saves, compiles, uninstalls, and logs into the conversion 13 # station controller connected to the wind turbine. The data read and written after successful communication can be seen.
