SETPA – Block for remote array parameter setting

Block SymbolLicensing group: STANDARD
PIC

Function Description
The SETPA block is used for setting the array parameters of other blocks in the model remotely . The block operates in two modes, which are switched by the SETF parameter. For SETF = off the remote parameter cs is set to the value of the input vector signal arrRef at the start and every time when the input signal changes. If the SETF parameter is set to on, then the block works in one-shot write mode. In that case the remote parameter is set only when rising edge (off on) occurs at the SET input.

The name of the remote parameter is determined by the string parameter sc (string connection), which has the form <block_path:parameter_name>. The path to the block whose parameter should be read can contain hierarchic levels separated by dots followed by the block name. The path can be either relative or absolute:

  • Relative – starts at the level where the GETPA block is located. The string has to be prefixed with ’.’ in this case. Examples of relative paths: ".CNDR:yp", ".Lights.ATMT:touts".
  • Relative to task – starts at the root level of the task where the SETPA block is located. The string has to be prefixed with ’%’ in this case. Examples of paths: "%GAIN:k", "%Motor1.Position:ycn".
  • Absolute – complete sequence of hierarchic levels down to the block. For referring to blocks located in the driver task (see the IOTASK block for details on configuration) the ’&’ followed by the driver’s name is used at the beginning of the absolute path. Examples of absolute paths: "task1.inputs.ATMT:touts", "&EfaDrv.measurements.CNDR:yp".

The order and names of individual hierarchic levels are displayed in a tree structure in the REXYGEN Diagnostics program.
