Profibus circuit board
Function
Flashing red at different frequencies
Flashing green at 1 Hz,
0.5 s on, 0.5 s off
Flashing green at 2 Hz,
0.25 s on, 0.25 s off
This green LED lights if the bus connection is OK.
This red LED lights if the bus connection is interrupted. Check the external bus configuration.
A bus line must be terminated with a terminating resistor. Note that a terminating resistor can also
be present in the connector and select the switch position accordingly. Switch up = resistor On.
Only one terminating resistor is permitted at the end of a Profibus line.
You can set the Profibus address using the software as follows:
A value from 0 to 125 can be set under "P-INTERFACE/P-Fieldbus/P-Profibus/Modbus/P-Profibus/
BUS address".
If you specify the value 0, the address will be set by the hardware. In this case, set an address in
the range 0 to 99 using a screwdriver.
Flashing at 1 Hz, 0.5 s On, 0.5 s Off
Flashing at 2 Hz, 0.25 s On, 0.25 s Off
Flashing at 4 Hz, 0.12 s On, 0.12 s Off
Off
