AS 488/TM | M02.02 |
2.4 Installation of the Reloadable DP Driver Blocks (DPAE, DPAA, DPBE, DPBA)
In addition to the execution system and the standard blocks of the AS 488/TM, your memory card contains a
To do this, install your "Commissioning terminal" and transfer the blocks from your memory card to the user memory of your AS using the operation "LA:DP_TREIB.NL;". The loaded blocks must then be parameterized to the type numbers provided in their application, and activated. You activate the parameter settings in the AS input mode using the input instruction "BT,DP:@;".
Set the desired type numbers of the DP blocks in the parameterization display using the parameters 1, 3, 5 and 7. If this blocks already are existing in the AS, the existing type numbers were accepted. Your parameter settings are accepted using the parameterization input "P,9,1;", and the blocks are stored in the user memory of your AS. The activation procedure can be previously aborted using "P,11,1;". The reloaded file is then no longer present in your AS. However, you can carry out the installation procedure from the beginning.
If you already have installed DP driver blocks and you want to update your system software, you have to update the algorithm of the DP driver blocks!
After successful activation, the user structure and the driver blocks must be
Note: | The data structures of the DP driver for CP581TM (in AS230/235) and |
| AS 488/TM are identically, but the program algorithms have to be exchanged. |
| With transfering of old user structures to AS 488/TM, following steps have to be |
| done: |
| - Install matching driver programs: "BT,DP:@;" (see above). |
| - Input again the parameters BGNR and BADR in all block instancies, even if |
| there value doesn't change (the check has to be run through). |
Note: | DPAE driver and analogue input modules with NAMUR range of values for |
| wire breakage |
| The DPAE driver does not know the NAMUR range of values for wire breakage |
| (e.g. AE module 6ES7 331−7RD0). However, with correct configuration, the AE |
| modules can be made to return the S7 standard value, 7FFF (hex), if a wire |
| does actually break, this is then interpreted by the DPAE driver as a wire |
| breakage: in order to do this, the release of the wire breakage diagnosis should |
| be parameterised using COM PROFIBUS (further information can be found in |
| the S7 manual |
| no. |
