 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.
