Note: At power on , OK LED is steady ON for approximately 5 seconds. Here it sends requests to device connected
on serial port .
If a device connected on serial port is not detected , OK LED blinks for 10 seconds and again steady for
approximately 5 seconds as Profibus Gateway (Gateway 500) sends requests to serial ports device.
This process is continued until a device connected on serial port is detected.
If that device is detected, Profibus port is initialised.
After successful Profibus initialisation, gateway 500 starts exectuting the project blocks.
At this point , Ok LED is steady ON. serial port and Profibus LED are blinking.
Now , if the gateway 500 detects that Profibus master is not present then it stops the block execution and
continuously waits for Profibus Master.
At this time OK LED is steady on and serial port and Profibus LEDs are off.
