Connecting the VIBROCONTROL 18xx to a 

PLC/PC  

EN 

 

 

 

UNRESTRICTED DOCUMENT 

9.2 

RS-485 interface 

The VIBROCONTROL 18xx vibration monitor allows "Daisy-Chain" connection. Up to 254 devices 
can be addressed individually in an RS-485 chain of devices. 
We recommend not connecting more than 50 devices together. 
 

 

NOTE 

The RS-485 interface is used for internal communication of the devices. It is not possible to 
access a device directly via the RS-485 interface. To set up communication with a PC, a 
VIBROCONTROL 1803/04 is also needed (see also  
8.2 VIBROCONTROL 1803/1804 Communication Module  
Ethernet Bridge). 

  

 

To use the RS-485 interface, connect the yellow connector (marked: "RS-485") at the front of the 
VIBROCONTROL 18x0 enclosure to the RS-485 chain of devices using a two-wire twisted and 
shielded cable.  

 

The cable must be terminated with a 120-

Ω resistor at both ends, i.e. on the PC side and at the last 

device on the RS-485 chain of devices.  
 
The VIBROCONTROL 18xx vibration monitor has a built-in 120-

Ω terminating resistor which can 

be used for this purpose. 
To switch the terminating resistor on, use the small left/right sliding switch behind a small hole on 
the front of the VIBROCONTROL 18xx enclosure.
