JSONer Zpět

JSONer library for serialize and deserialize JSON for B&R PLC.

Usage

There are 2 Function for user:

• JSON_serialize: create JSON string from variable
  • pVarName: PV name with program name, if it's not global var.
  • pUserVarName: ADR of string with variable name - only used with array.
  • pOut: ADR of buffer.
  • sizeOut: size of output buffer.
  • size: IN/OUT variable for check output size.
• JSON_deserialize: parse JSON string into PV
  • pVarName: PV name with program name, if it's not global var.
  • pUserVarName: ADR of string with variable name - only used with array. Internally <> 0 and name is not used. Set to 0, if PV is STRUCT.
  • pIn: ADR of JSON string.
  • sizeIn: size of input string - for internal check.

Output is ENUM JSONer_Status_e: JSONer_Ok is 0 and another states are Errors.

Just call the function to generate values.

Limitation / Known bugs

• Array must start with index 0 and be positive. Dimension can be only one.
• ENUMS not supported. Use UDINT.
• WSTRING is not implemented, but have place in program.
• Input STRING are not modified, only copied to output. That's mean, that $n are not transfered to \n etc.
• Speed and memory usage?
