1 green LED is provided to indicate when the interface has achieved the 
DATA_EXCHANGE state with the network master.  This serves as a convenient 
indicator that the master and drive are configured properly and are exchanging data. 
 
 
Isolation 

The network interface portion of the Profibus-DP board is fully optically-isolated for 
optimal noise-immunity characteristics. 
 
 
Network Connector 

The network interface is a standard DB9 connector with the following signals 
provided: 
 

3 

Profibus network “B” (positive) data line 

In/out 

4 

RTS signal – direction control for fiber optic network 
interface 

Out 

5 

DGND – power supply ground internally connected to the 
interface board’s isolated ground  

- 

6 

VP – power supply +5v internally connected to the 
interface board’s isolated P5. 

- 

8 

Profibus network “A” (negative) data line 

In/out 

1, 2, 7, 9 

No connection 

- 

 
In addition to the above signals, the metallic housing of the DB9 connector is 
connected to the shield section of the interface board.  The shield section contains a 
plated connection point where a ground wire can be attached to connect the network 
cable shield to ground.  Refer to section 3 of this document for more information 
related to grounding. 
 
 
Input/Output Data 

The interface’s cyclic data sizes are fixed at 8 bytes of output (control) data 
configured as 4 words, and 16 bytes of input (status) data configured as 7 words and 
2 bytes.  For detailed explanations of the format and usage of this data, refer to 
sections 9 and 10 of this document.
