4th step: Edit STEP 7 project
The description of this step is based on the included sample program.
S Copy the sample program for the FC 56 to the STEP 7 project which you just
set up.
S Continue as shown below based on the number of MOBY channels (number of
SLGs).
– Declare UDT 10 in DB 56 and related MOBY command/s (UDT 50) in DB 57.
– Display DB 56 in the "data view" of the editor, and adjust the "input
parameters" in the "Aktualwert" column. For simple commissioning of MOBY,
all you have to do is adjust the parameters ASM_address and ASM_channel
to the HW Config addresses. General requirement: All MOBY channels
(SLGs) use the same command (DB 57) and the same data (DB 58).
These two variables
must be adjusted for
each channel.
The pointer to command_DB can retain the
default value for initial commissioning.
Figure 8-4 Editing DB 56
S Edit OB 1, and program a cyclic FC 56 call for each channel. Declare a flag for
the command start for each MOBY channel.
S Set the variable init_run in the parameter DB in OB 100 for each MOBY
channel.
