Alternative Cable Repeater (SALT)

The diagnostic alternative cable repeater (SALT) enables PROFIBUS communication over non-standard cable. Rotary switches allow setting the impedance. The user can verify the bus signals with the built in oscilloscope which is identical to the COMbricks SCOPE repeater module and accessible through the web server.

Introduction

PROFIBUS networks that have not been wired with proper cable or where it is mandatory to use existing twisted pair cable are not uncommon. This product is an excellent tool to modulate PROFIBUS signals on non-standard infrastructures. It can also be used to increase the idle line voltage on segments where interference causes communication disturbances. The large connectors allow specialty cable and more cable stress.

Applications

Alternative Cable Repeater (SALT)

The repeater channel and the integrated oscilloscope are directly connected with the ProfiTrace OE core in the Head Station. Scope images and busmonitor data are directly available in the web server. The data traffic is constantly monitored for glitches which are digitally filtered out. It is able to drive 31 devices and has increased signal strength.

2 Rotary switches, one for the middle resistor and one for the 2 pull-up resistors, manipulate the values of the termination network. The combination of both set the impedance and the level of the idle voltage. At the other end of the cable another SALT repeater or the T1-PEPPER has to be placed (termination at both ends of the cable).
