 PLC INTERFACE (PROGRAMMABLE LOGIC CONTROLLER) 
 
Note: 
Reminder: The PLC (Programmable Logic Controller) function must 
be selected in the configuration menu (Interface: PLC).  
 
The role of the PLC interface option is to allow control of the measurement instrument by a 
system such as an industrial PLC. 
 
 
 
 The implementation of the safety loop is essential. The control of the device 
and therefore the generation of a dangerous voltage by PLC can be done from a point 
where visual inspection of the device is not possible.
