The PROFINET field devices, communication modules and the MC-PND communication card are
provided with LED status displays for diagnostics.
Furthermore, the »PLC Designer« provides a function library for diagnosing PROFINET.
Note!
Siemens »STEP7«: "Node blinking test"
SIEMENS »STEP7« provides a "node blinking test" which permits an optical verification
of the physical connection between the Siemens S7-PLC and a PROFINET node (I/O
device).
Here, both LEDs are blinking simultaneously twice per second (2 Hz) at the RJ45 socket
of the I/O device.
In »STEP7« version 5.5, this function is defective and does no create the wanted result.
