Modbus Slave 

1. 

 

Device setting 

Use a controller as Modbus Slave to input/output data with Modbus Master. 
Following is an example case when the product containing the CPSN-DO-08BL and CPSN-DI-08BL 
in the slots is used as Modbus Slave, and QModMaster is used as software of Modbus Master. 
QModMaster can be downloaded free through the URL below. 
http://sourceforge.net/projects/qmodmaster/ 
Connect the controller to QModMaster pre-installed CODESYS Developing PC.
