Transparent Communication Function 
 

 

 

With the transparent communication function, transparent data transmission and reception between 
computer and programmable controller and programmable controller and programmable controller is 
possible. 
 
Storage and extraction of the communication data at the programmable controller is carried out by 
reading from and writing to the ET-LAN unit’s shared memory communication buffer. The communication 
requests are performed by switching on and off bits in the I/O or shared memory handshake areas. 
 

 

 

 Key Point: 

- 

With transparent communication, either the computer or programmable controller specifies the IP 

address, and they open a mutual connection with the communication partner. After opening a 
connection, communication processing on the programmable controller side is done by the ladder 
program reading from and writing to the communication buffer of shared memory, and executing the 
communication requests. 

- 

With the transparent communication function and the MEWTOCOL communications function (computer 

link and data transfer), you can simultaneously use a maximum of eight connections with one ET-LAN 
unit.
