3.2.4 Data In (SPI: MISO)
Data is read in on the synchronous serial interface via this signal. The most significant bit of the
data is expected first.

In SPI mode this Pin serves as data transfer from Slave to Master.
3.2.5 Load In (SPI: MOSI)
This pin is the strobe signal for the input data of the synchronous serial interface.

In SPI mode this Pin serves as data transfer Master to Slave.
3.2.6 Clock (SPI: SCK)
This signal is the clock line for the synchronous serial interface. That signal is equally valid for
data input and data output.
3.2.7 -Reset In
• A reset generator is on board; with it in the normal case the reset input is not required. In this
case the reset input has to be connected with VCC, in order to avoid interferences (see chapter
3.6).
• If the customer’s application has to initiate a reset of the UNIGATE
®
FC, then the reset input
can also be connected with a reset output of the customer’s application instead of connecting it
with VCC. Here all specifications of the reset signal, mentioned in chapter 3.2 have to be kept.
The reset-impulse needs to last at least 10 µs.
3.2.8 Errror LED
A red LED can be connected to this line (siehe Kapitel 3.6). It can have the following conditions:
Off No error
Flash PROFINET user flash test
On Error
3.2.9 Ground
This pin is directly connected to earth line (drilling Ø 3 mm) of the UNIGATE
®
FC.
3.2.10 State-LED
A green LED can be connected to this line (see chapter 3.6). It shows the bus status and can
have the following conditions:
Off Bus not started
Flash 10Hz Error
Flash 2 Hz Bus started, waiting for connection / configuration mode
On connected
3.2.11 -Config Mode
If the pin has the level GND, then the FC starts in the configuration mode.
