Therefore the PLC responds to 

192.168.0.34

 which is clearly the wrong address 

and the FieldServer will not see the response. 

 

Example: - Class A Addressing 

 

A FieldServer with IP address=192.168.1.81 and system_node_id=34 polls for 
data from a PLC with IP address =192.168.2.

33

 and Subnet mask = 255.255.0.0 

 
The PLC responds to 

192.168.2.

33

 

   255.0.0.0 
   192.x.x.y 
 

Where x is always set to zero and  
y is equal to 34 (The PLC obtains the node ID of 34 by 
inspecting the contents of the poll message.) 
 

Therefore the PLC responds to 

192.0.0.34

 which is clearly the wrong address 

and the FieldServer will not see the response. 

 

Thus, if the PLC is using Class A/B IP addressing then the 3

rd

 (Class B) or the 

2nd and 3rd (Class A) bytes of the address must be zero as must the 
FieldServer's if communications are to work. 
 
There are ways around this problem, we believe. The solution requires usage of 
the Omron PLC routing table. For more help consult with Omron's Tech Support.
