Local Constants
| Constant Name | Resolution | Units | Value |
| TESTNORES_CNT_U08 | 1 | Cnt | 0U |
| TESTPASSD_CNT_U08 | 1 | Cnt | 1U |
| TESTFAILD_CNT_U08 | 1 | Cnt | 2U |
Note : These local constants are used in place of SIGQLFR_NORES (0U), SIGQLFR_PASSD (1U) and SIGQLFR_FAILD (2U) that are used by FDD because the datatype SigQlfr1 is not necessary for this purpose as well as it not possible to get them defined from RTE when no client call that uses this datatype as one of its arguments is defined by current design.
