CHECK PC MC COMMUNICATION (0xE5)

Code: 0xE5
Description: This command is used to test the communication from the control system to the module.
Parameters (master -> slave):

• Data can be sent in one block in the following sequence:
  

  Data type	Value HEX	Value DEC
  Float	0x19 0x04 0x9E 0xBF	-1.2345
  Float	0xA4 0x70 0x3C 0x42	47.11
  Int32	0x11223344	287454020
  Int32	0xFFEEDDCC	-1122868
  Int16	0x0200	512
  Int16	0xAFFE	-20482

  
  

  The data must be fragmented.

• In order to transfer individual data packets for testing purposes, first transfer the test data and then the code indicating the content of the text data:
  • Send floating point value ,,-1.2345'' (0x19 0x04 0x9E 0xBF) with affixed parameter code (0x0101)
  • Send floating point value ,,47.11'' (0xA4 0x70 0x3C 0x42) with affixed parameter code (0x0202)
  • Send Int32 value ,,0x11223344'' (287454020) with affixed parameter code (0x0303)
  • Send Int32 value ,,0xFFEEDDCC'' (-1122868) with affixed parameter code (0x0404)
  • Send Int16 value ,,0x0200'' (512) with affixed parameter code (0x0505)
  • Send Int16 value ,,0xAFFE'' (-20482) with affixed parameter code (0x0606)

Response (slave -> master): ): If the respective test value has been interpreted correctly, the module responds with ,,OK (0x4F4B)''. When all test data is transmitted in one block, the module responds with ,,OK (0x4F4B)'' and an affixed byte specifying in bit code the data that could not be correctly interpreted (bit is set to ,,1'').

• Bit 1: first floating point value (-1.2345) not recognized
• Bit 2: second floating point value (47.11) not recognized
• Bit 3: first Int32 value (0x11223344) not recognized
• Bit 4: second Int32 value (0xFFEEDDCC) not recognized
• Bit 5: first Int16 value (512) not recognized
• Bit 6: second Int16 value (0xAFFE) not recognized

Example: See examples

Note: This command is used to check the integrated drivers. This command is not required for normal operation. It is possible to test the data exchange from the control system to the module, using individually defined values or predefined data packets that require fragmentation.

The code parameter is attached at the end of the response to ensure that the test data is sent to the position at which the real data is stored.
