3.4 

Basic operation of the PLC  

 
In order to operate the filter it is absolutely important for the user to be familiar with the operation method of the PLC 
through its HMI display as described briefly in this chapter and in details in Amiad’s “HMI_AMF93_092010.doc” text book. 
It is also very important for the user to understand the system status terminology, especially it is important to distinguish 
between the following 3 terms:   

 

System Fault

 – a major malfunction of one (or more) of the system components that cussed the whole system to 

halt.   

 

System Alarm

 – a second level notification indicating a malfunction of one (or more) of the system components. 

In multiple filters installation this may indicate a malfunction that stopped one of the filters while the rest of the 
system filters continue to work. In a single filter installation such malfunction leads immediately to System Fault.    

 

System Attention

 –

 

a malfunction of one (or more) of the system components that was overcome automatically 

by the control system of the filter. For the user knowledge only.  

 

The electronic control system of the AMF² filter consists of two major components:  
 

1.

 

The  PLC  –  Siemens  S7-200  PLC;  this  component  contains  the  operational  algorithm  of  the  filter  and  is 
responsible  for  its  actual  operation.  It  is  important  for  the  user  to  understand  that  once  running  the  PLC 
software operates the filter independently; even without being connected to any user interface device. The PLC 
software contains internal default values for all the required operation parameters and once it is connected to 
power supply it operates the filter. 

 

2.

 

The HMI panel – This component serves as a user interface device connecting between the internal PLC software 
and the user and allowing data exchange between the PLC and the user. Amiad provides several HMI panels to 
be connected to the Siemens PLC; the selection of the appropriate panel depends on the specific filter, project 
or site requirements. This document describes the Amiad HMI software based on Siemens TP-177-B 6” panel.    

 
3.4.1. Basic operation of the panel  
 
The  TP-177-B  panel  is  a  touch  screen  panel;  it  contains  no  keyboard  and  its  operation  is  done  by  touching  graphical 
elements appearing on it screen.
