SMB30 to SMB194 and SMB566 to SMB749 (S7-200 SMART read/write special memory)
The S7
-200 SMART CPU performs these actions:
•
Reads configuration/control data from special memory
•
Writes new changes to the system data in special memory.
Read system status
from CPU
Write (send) control
commands to the
CPU
Your program can read an
d write all SM addresses in this range. The
normal usage of SM data varies according to the function of each a
d-
dress.
SM addresses provide a means to access system status data, configure
system options, and control system functions. In run mode,
continuous
scanning of your program provides for continuous access to special
system features.
