Technical description

The senddata command sends the SEND DATA message to MD30 and parses the response.

The data interval is given as a parameter in milliseconds. If the parameter value is:

  • 0 = only one data set is sent as a response

  • 25 ... 5000 = message sending starts with the defined data interval

Only numeric values are counted as parameters.

Example 1

Data request with data interval 0.

Only one data set is sent as a response.

Example 3

Data request with data interval 10.

The data interval is not valid, which causes an invalid data error (error code = 4).

/> senddata 10
/> Unit ID: 1, Client ID: 0, ID: 0x20, Nb: 21, Len: 2, icd_version: D, Err: 4
