Using the
Profibus
functionality the integrated Profibus DP master is
connected to Profibus via RS485 interface. At master operation there is
access to up to 125 DP slaves. For this the project engineering happens in
the hardware configurator from Siemens. Please regard there may be a
delimitation of the maximum number of configurable DP slaves by the use
of the Siemens SIMATIC manager.
For state display the CPU has a row of LEDs at its front side. Dependent
on the mode of operation these give information according to the following
pattern over the operating condition of the Profibus part:
RUN
green
ERR
red
DE
green
IF
red
Meaning
○ ○ ○ ○ Master has no project, this means the
interface is deactivated respectively PtP is
active.
● ○ ○ ○ Master has bus parameters and is in RUN
without slaves.
● ○
☼
○
Master is in "clear" state (safety state). The
inputs of the slaves may be read. The outputs
are disabled.
● ○ ● ○
Master is in "operate" state, this means data
exchange between master and slaves. The
outputs may be accessed.
● ●
☼
○
At least 1 slave is missing.
○ ○ ○ ●
Initialization error at faulty parameterization.
○ ● ○ ●
Waiting state for start command from CPU.
