LED status indicators for the EM DP01 PROFIBUS DP
The EM DP01 PROFIBUS DP module has four status LEDs on the front panel to indicate the
operational state of the DP port:
●
DIAG LED:
–
Dual color (red / green) LED indicates the operating state and fault status of the
EM DP01
–
Flashing red: Upon startup, until the EM DP01 is logged in by the CPU, or if there is a
fault in the EM DP01
–
Flashing green: While the EM DP01 is waiting on configuration and parameterization
from the S7-200 SMART CPU (immediately after login), or during a firmware update
–
ON green: No fault is present and the EM DP01 is configured
●
POWER LED:
–
ON green: If user 24 V DC is applied
–
OFF: No user 24 V DC
●
DP ERROR LED:
–
Flashing red: If there is an error in the I/O configuration or parameter information that
the DP master writes to the EM DP01
–
ON red: If DP communications are interrupted
–
OFF: No error or data exchange has never been established
●
DX MODE LED:
–
OFF: After the S7-200 SMART CPU is turned ON as long as DP communications are
not attempted, or if DP communications are interrupted
–
ON green: Once DP communications have been successfully initiated (the EM DP01
has entered Data Exchange Mode with the DP master); remains on until the EM DP01
exits Data Exchange Mode
Note
If DP communications are lost, which forces the EM DP01 to exit Data Exchange Mode, the
DX MODE LED turns OFF and the DP ERROR LED turns red. This condition persists until
the S7-200 SMART CPU is powered off or Data Exchange Mode is resumed.
