PROFI-8455 – PROFIBUS Remote I/O Unit
Introduction
This user guide introduces the user how to implement the PROFI-8455
into their applications in a quick and easy way. Therefore, it only provides
the basic instructions. For more detail information about the PROFI-8455,
please refer to the PROFI-8455 user manual in the ICP DAS product CD or

PROFI-8455 Hardware Structure
Power Input
PROFI-8455 Connector and Pin Assignment
The PROFIBUS connector is a standard 9-pin D-Sub connector, there are
only 4 pins used in PROFI-8455. The pins VP and GND support the 5 volt
power to active terminal resistor, and the A-Line and B-Line is the data bus.

Page 2: Status Indicator
Status Indicator PROFI-8455 provide three types of status indicators, they are PWR LED (yellow), ERR LED (red) and RUN LED (green). Status Indicator Meaning Recommend solution ERR ON & PROFI-8455 is offline Check the address setting of RUN OFF with no valid baud rate PROFI-8455 and DP-master. -
Page 3: Terminating Resistors
PROFIBUS device has to fit with an active terminal resistor at both first node and last node. The connection of active terminating resistors is shown in above circuit diagram. The PROFI-8455 doesn’ t have any terminating resistors inside. Therefore, users must add the terminator in external.

- Page 6 PROFI-8455 – Q&A 1. Q: How do I know the status of the PROFI-8455? A: You can observe the RUN LED in PROFI-8455 panel. If RUN LED is light, data is exchanging. Otherwise it must be error in the previous state.
- Page 7 If you want to use the high sampling module, I-8017H and I-87017 is the best choice. 6. Q: how can I use the additional function of I-87082? A: Please refer to the “Byte Order and Data Address” chapter in the PROFI-8455 user’ s manual.
