3.4.3 Assigning Parameters in DB1 for the FMA Services
The default settings of DB1 do not enable the FMA services. To activate the FMA services, set the
following parameters in DB1:
• The job number A-NR=200 (200 is reserved for FMA services)
• The location of a status byte (STB) for FB L2-SEND and FB L2-RECEIVE.
The status byte displays the status of the transmit or receive jobs and informs you of possible
errors. Section 5.4 explains in detail the structure and the evaluation of the STB. The STB
parameter settings provide you with access to all the FMA services described in section 3.6.2,
except MAC_EVENT. If you want to use MAC_EVENT, you must specifically activate this service
in DB1.
Figure 3-9 shows DB1 with parameter settings for all FMA services.
The procedures to set and modify parameters in DB1 and to transfer DB1 are described in detail in
section 1.4.
