Note
The screens of the user interface (see Figure 8-2 and description of each screen,
Table 8-1) contain display fields and input/output fields. These fields contain values
of configured variables.
S
The display fields are addressed to the DB-SS ("Control 2," DB1000) and are
read directly from the FM 353.
S
The input/output fields are addressed to the user DB No.: 1 (Control 1-CPU).
− Transmission of these values occurs from the OP 07 to the CPU into the
user DB. These values (if needed) must be transmitted to the FM 353 by
the user program.
− If certain values or control signals can be written only under the right condi-
tions (e.g. if axis is necessary on HOLD or selection of a certain operating
mode), then the user program must ensure, by analyzing the response sig-
nals, that these conditions are met.
