+5V and GND_BUS are bus terminators. Some devices, such as the optical transceiver (RS485),
may need to obtain power through these pins.
On some devices, the transmission and receiving directions are determined by RTS. In normal
applications, only A-Line, B-Line, and the shield layer need to be used.

This indicator is on when the expansion card is
establishing a connection with the control board; it blinks
periodically after the expansion card is properly
connected to the control board (the period is 1s, on for 0.5s,
and off for the other 0.5s); and it is off when the expansion
card is disconnected from the control board.
This indicator is on when the communication card is
online and data exchange can be performed.
It is off when the communication card is not in the online
state.
This indicator is on when the communication card is
offline and data exchange cannot be performed.
It blinks when the communication card is not in the
offline state.
It blinks at the frequency of 1 Hz when a configuration
error occurs: The length of the user parameter data set
during the initialization of the communication card is
different from that during the network configuration.
It blinks at the frequency of 2 Hz when user parameter
indicator
data is incorrect: The length or content of the user
parameter data set during the initialization of the
communication card is different from that during the
network configuration.
It blinks at the frequency of 4 Hz when an error occurs in
the ASIC initialization of PROFIBUS communication.
It is off when the diagnosis function is disabled.
