Parameter data for read access
Errors when exchanging parameter data are reported by the module in the error
flags TIMEOUT, BUF_OV and PRM_ERR.
When the last parameter has been transferred to the module (MORE_PRM =
FALSE), the entire parameter set is checked by the module and accepted if
correct. Otherwise, the module returns a parameterizing error (PRM_ERR =
TRUE).
