CTI 2500 Installation and Operation Guide V2.8

4.4  Profibus DP I/O 

The CTI 2500 Controller supports I/O devices that comply with the Profibus DPV1 standard. The 
following Remote Base Controllers can be used to allow CTI 2500 modules or Siemens 
SIMATIC Series 505

®

 modules to be used on the Profibus network: 

•

  CTI 2500-RBC Profibus Remote Base Controller 

•

  Siemens SIMATIC

®

 505-6870 Profibus Remote Base controller.    

The CTI 2500 controller can communicate with up to 112 Profibus slave devices, reading and 
writing up to 244 bytes per slave. The controller supports modular slaves with up to 128 slots 
(firmware version 6.07 and above). Profibus network data rates up to 12Mb are supported.    

NOTE: 

The actual amount of data that can be exchanged with a slave is dependent on the capability of the slave. 

The total amount of data that can be exchanged is limited by the I/O capability of the controller model. 

Network data rates may be limited by the network configuration.   

4.4.1  Connecting the Profibus Network  

Cable Selection 

The Profibus network attaches to the Profibus DP connector on the front panel of the CTI 2500 
controller using shielded twisted pair cable. The following table specifies the characteristics of 
the cable.  
 

Characteristic 

Requirement 

Impedance 

135 – 165 ohm (3 – 20Mhz) 

Capacitance 

< 30pF/m 

Resistance 

<110 

Ώ/km

 

Conductor Area 

 0.34mm2 (22 AWG) 

Cable Diameter 

0.34 mm  

 
The following cables meet the Profibus DP cable specifications:  

•

  Belden 3079A  

•

  Belden 3079E (Hi-Flex) 

  
The cable incorporates two color coded wires (red and green) surrounded by a shield. One wire 
is used for Transmit/ (TX/RX +) and the other for Transmit/Receive (TX/RX -).  The 
color used to connect to TX/RX+ is arbitrary; however, the same color must be used throughout 
the system. Do not cross the TX/RX + and TX/RX – signals.
